NavRules - Mintaka Innovations

NavRules
Mintaka Innovations
Genre: Navigation
Price: $15.99
Release Date: March 7, 2011

The best way to learn the Nautical Rules of the Road.

NavRules provides all the questions, answers, explanations and resources to help you master the Nautical Rules of the road. For all mariners, from kayakers to ship captains.

Product Description:

Based on the International and US Inland Navigation Rules along with the published edition of the USCG database of license exam questions, this App helps you master the Navigation Rules using a practice exam driven methodology.

Using NavRules you generate practice exams where you:
• control the number of questions,
• control the scope of the questions (international vs inland),
• specify a filter (a text string that must appear in the question),
• specify the rule the questions pertain to,
• identify whether the question has been previously answered or not, or answered incorrectly or not.
This gives you control over the tests that are generated so you can focus your learning experience.

After taking an exam you can review the results to see:
• which questions were answered correctly,
• for incorrect answers the correct answer,
• the rule the question pertains to so you can understand the context of the question.

Every practice exam you take tracks your results relative the the Navigation Rules Question Pool. By browsing the Question Pool you can see your progress on understanding each rule.

For each rule NavRules reposts:
• your coverage (number of questions you have answered) and,
• your proficiency (the percentage of questions you have answered correctly).

If you want to study a rule you can link directly to the questions related to that rule and choose the answers. In this "review" mode you get immediate feedback on whether your answer is correct (but these results are not recorded and do not impact your rule coverage or proficiency).

The Flash Card mode lets you see all the diagrams used in the tests and from each of them see the questions that reference that diagram.

The included Rule Book provides:
• index to US Inland, International and Canadian Rules,
• link to all illustrations used in the Navigation Rules,
• link to all vessel lights by vessel type,
• definitions,
• demarcation lines,
• special terminology,
• distress signals
• references.

Other features include:
• over 1200 answered and referenced questions on the Navigation Rules,
• complete copy of the Navigation Rules,
• custom design your practice tests by number, filter, and type so you can focus on what you need to learn,
• rules are clearly identified as Inland and International or both,
• all practice tests results are stored until manually deleted,
• Canadian Modifications to the Navigation Rules.

Tactical NAV - TacNav Systems LLC

Tactical NAV
TacNav Systems LLC
Genre: Navigation
Price: $8.99
Release Date: February 14, 2011

BACKGROUND:

Built from the ground up in the rugged mountains of eastern Afghanistan, Tactical NAV (also known as TACNAV-X) was developed by a U.S. Army Field Artillery officer with the vision of crafting a low-cost and highly accurate mobile navigation platform tailored for the U.S. military.

Tactical NAV’s journey began in the Pech and Korengal Valleys of Kunar Province, Afghanistan.

U.S. Army Capt. Jonathan J. Springer, a Field Artilleryman serving as a Fire Support Officer with the 101st Airborne Division (Air Assault), embarked on the development of this tactical navigation platform immediately following the memorial services for Spc. Blair D. Thompson and Spc. Jared C. Plunk, who were killed in action on June 25, 2010.

Despite initial rejections by the Department of Defense, Captain Springer remained steadfast in his mission to continue developing Tactical NAV — even to this day. His ultimate goals were (and still are) to make a positive difference for other soldiers and service members and to honor the men and women killed and wounded in battle.

He used his life savings to fund and develop TACNAV-X, all with the ultimate hope of saving military lives, and helping his fellow service members in accomplishing their missions at home and abroad.

Tactical NAV officially launched on the App Store on February 14, 2011.

BUILT FOR ACCURACY:

TACNAV-X’s performance accurately matches that of the AN/PSN-13 Defense Advanced GPS Receiver (DAGR).

MISSION:

Empower military service members with a highly accurate and powerful mobile navigation platform.

VISION:

Assist and support our nation’s service members with their mobile navigational needs and enable them to operate and win in both training and combat environments.

BOTTOM LINE:

Tactical NAV has successfully undergone evaluation against Nett Warrior, ATAK, BFT, and other military targeting and navigation systems. Its accuracy is within 1mm of officially approved DoD equipment.

IAPs & SUBSCRIPTIONS:

Currently, offline mapping mode is available as a monthly or yearly subscription, or as a one-time purchase. Drawing mode, previously an in-app purchase, is now included free for all users.

All revenue generated from these features contributes to further development and updates, and a portion of the proceeds are donated to charities that specifically benefit disabled veterans.

KEY FEATURES:

• A military-quality precision targeting platform
• Purpose-built for the individual Soldier
• Offline mapping capabilities (complete usage of the app with no emission of a cellular signal)
• WGS-84 standard (MGRS, UTM, BNG, and USNG coordinates)
• Tactical drawing mode (useful for mission planning, building overlays, targeting, etc.)
• Waypoint plotting functionality with military graphics (per FM 1-02.2)
• Compass “FastLock” function for capturing quick and precise azimuths
• Snap and save photographs onto the main map to increase situational awareness
• Location, waypoint, and photo-sharing capabilities (via email and text)
• One-button night mode function for low-light situations
• Apple Watch support included for free
• ‘Go to Grid’ feature for precision planning, drawing of overlays, and dropping waypoints
• iOS/iPadOS native code built for austere and contested environments

IMPORTANT NOTES:

The Department of Defense does not endorse Tactical NAV and TACNAV-X. The app should not replace a government-issued device during life-threatening or combat operations.

SUPPORT:

If you have any questions about the app, please contact Jonathan Springer directly at jon@tacnavx.com.

Holding Pattern Trainer - FLEMINGER MEDIA LLC

FLEMINGER MEDIA LLC
Genre: Navigation
Price: $4.99
Release Date: August 16, 2011

Save time and money on your instrument flight training by mastering IFR holding pattern entries at the comfort of your own mobile device.

Make IFR flight training easier!

Is the following scenario familiar? You receive a holding clearance from ATC, and only have a couple of minutes, sometimes only a few seconds, to choose the correct entry. By the time you've figured out what's going on, you've already passed the holding fix and don't know what to do next.

If this sounds familiar, then you need not to worry. Confusion during holding entries happens to practically almost every new instrument student. Even instrument-rated pilots occasionally have the same problem — when they don't get enough practice.

Holding Trainer solves this problem and as a result, cuts the time you have to spend on expensive flight and ground lessons. With Holding Trainer, you can practice on your own time and convenience, so that choosing the best holding entry in the air becomes a breeze.

Features:

-Entry Trainer - Drills you on choosing the best holding entry. Practice until choosing holding entries becomes second nature and impress your flight instructor with your skills.

-Holding calculator. Solve and visualize any holding scenario by entering your current bearing to the fix and a outbound or inbound holding radial.

-Holding tutorial - learn how to choose the best holding entry quickly and easily.

Holding Trainer for iOS is a complete rewrite based on my popular Flash-based desktop Holding Trainer app available on pilotscafe.com.

***Don't get "stuck" next time you receive a holding pattern clearance!***
----------------------------------
For only a fraction of the cost of one ground lesson with your flight instructor, you can practice this important instrument skill at your own pace and save hundreds of Dollars on figuring out holding entries in the air.

This is a great tool for anyone training towards their instrument checkride, CFII, proficiency check, or simply trying to improve their holding patterns.

ChalkLink, LLC
Genre: Navigation
Price: $1.99
Release Date: May 16, 2021

Welcome to the BetterMaps ZooMap app, Bronx Zoo version. Our custom interactive map plans the shortest route to your destination. Our mapping works even if you don't have a signal (web-based maps can't do that). Find animals, rides & attractions, food and more and our map will guide you to your destination. Get food (or a beer) and find the bathrooms when you're done (quickly!) Walk around knowing you don't have to remember where you parked (we do that for you - then bring you back to the car at the end of a long day). So have fun and get mapped. Free! - other zoos coming soon.

ZooMap is not affiliated with the Bronx Zoo but we are a New York company (located in Brooklyn), and we LOVE the Bronx Zoo. When our CEO saw people enter the zoo and rush to a poorly executed wall map or try to navigate using an outdated paper map (uh, save the planet much?) he knew we could help. Our goal is to increase your fun, while saving your time (and trees).

The BetterMaps ZooMap, Bronx Zoo version truly is the best way to explore the Bronx Zoo (more zoos are coming online very soon) without missing anything that you and/or the family want to see during your visit. The ZooMap digital guide brings you a whole new level of closeness to everything the Bronx Zoo has to offer. Once you have found what you are looking for, our custom algorithm shows you route overview, how away you are, and approximate time to walk there. Simply hit Go and just follow the blue line to get there. Our flashlight points you in the right direction (use your phone as a wayfinder). Veer off the path, no problem, our map adapts to your movements and reroutes instantly.

Tap onscreen icons, use the search bar or drop down menu to find animals, food, rides and attractions – even bathrooms and water fountains on those hot days. Soon you will be able to receive notifications concerning feeding times, ride closures or any other up to the minute information you need to have the best time possible in the zoo.

ZooMap Features

SAVE PARKING SPACE
-Upon arrival you can save your parking location and BetterMaps will bring you right back to where you parked at the end of the day – no more having to use your door lock fob to find your car beeping in the distance.

GET TO KNOW THE ANIMALS
-Use our menus to learn about the animals, species and where they are from.

GET DIRECTIONS VIRTUALLY ANYWHERE IN THE ZOO
-Find Animals, Exhibits, Rides, Restaurant and shopping, then click the MapMe walker icon. You will see how far and approximate time to walk there. Click Go and our live map will bring you to your destination. Veer off course and BetterMaps will adapt in real time.

BE IN THE KNOW
-Receive notifications updating you on ride and animal closures
-Receive discounts from surrounding businesses

FOR BUSINESS OWNERS: MALLS, ZOOS, PARKS, MUNICIPALITIES, AMUSEMENT
BetterMaps takes maps to a whole new level – the micro-level. We create maps for smaller spaces, such as zoos, amusement parks, cemeteries and even municipalities and outdoor malls. Use Google or Apple Maps to get you there, use BetterMaps to get around. check out our website: www.bettermaps.app

But we do more than just help you visitors navigate, we provide communications as well – send out the latest news and updates, tell your visitors what’s going on before they arrive.

Seasonal Spring

Price: $3.99
Release Date: November 2, 2013

Featured by Apple in “Best New Apps”!

Plan your next trip, mark places you want to go, and remember your favorite spots. Across town or across the world, you’ll never forget another place with Pinbox!

Add pins where you are, where you’ve been, or where you want to go. Pinbox makes it easy to quickly record and organize your important places into distinct maps for every activity, occasion, or geographic region.

Unlike other apps, Pinbox doesn’t force you to save all your places on a single map. You can make one map for your favorite local restaurants - make another map for your next business trip or vacation - and make another map for errands you need to run this weekend. The possibilities are endless!

Pinbox is about you and your places. It’s not a social network. You don’t have to create an account or enter your Facebook details to use the app. Your maps aren’t cluttered with random places bookmarked by strangers. Pinbox is simply the best app for privately bookmarking places that are important to YOU!

FEATURES

• Simple, easy-to-use interface
• Drop a pin for each place you want to remember
• Add photos, notes, and other details to each pin
• Choose from seven different pin colors
• Organize your pins into separate maps
• See your location in relation to your pins
• Send maps to other Pinbox users
• Send pins to Apple Maps, Google Maps, Waze, or Transit for directions
• Display maps in Standard, Hybrid, or Satellite
• Save up to 5,000 pins total

EXAMPLES OF MAPS YOU MIGHT CREATE

• Travel planning
• Favorite restaurants or restaurants to try
• Customer locations/sales calls
• Friends and family locations
• Real Estate listings
• Favorite hiking/biking trails
• Secret fishing spots
• Dog-friendly places
• Parking spots
• Favorite stores
• Multi-stop errands
• Potential photoshoot locations
• The list goes on and on and on…

Still not convinced? Here are a few of our favorite reviews…

“Pinbox is one of those simple apps that does one thing so well it feels frictionless”.
-- Stephen Grassie

“The interface is gorgeous - I would say that it looks like something Apple designed”.
-- Macaddict

“I have been using this to keep track of all the places the kids and I go so they can see how spread out our world is and they can see where all we have gone. Will use it forever”.
-- 1Cool Daddy

“This app is extremely useful and so simple to use. A lifesaver for keeping track of locations”.
-- Davies Photo

“I love this app. It is exactly what it claims to be. I have wanted this app since the smartphone was invented. So simple, and so many uses”.
-- T1Man

Using Pinbox on an iPod Touch or an iPad:
Like other map apps, Pinbox uses GPS to determine your location. iPods and Wi-Fi-only iPads do not have a GPS receiver. On these devices, Pinbox provides your approximate location using information based on your proximity to known Wi-Fi networks (when on and available). The more accurate the available information, the smaller the circle identifying your position on the map. This feature is not available in all areas. Known Wi-Fi networks are predominantly in urban areas. An internet connection is required to load maps, look up addresses, and search. Although Pinbox can be installed on iPads, it’s not formatted for the larger iPad screen - it runs doubled like all other iPhone apps.

Pinbox is the result of a collaboration between Scott D. Smith and Paul Burd. We sincerely hope you like it!

Tide Graph - Brainware LLC

Tide Graph
Brainware LLC
Genre: Navigation
Price: $1.99
Release Date: February 12, 2019

- Provided over 10 billion predictions
- Supports iOS 11+, Watch OS 4.3+, iPhone 7+

Tide Graph uses the harmonic predictions from thousands of US coastal stations and presents them in a fun and interactive graph. And now, in version 2.0 you also get an intuitive graph that shows sunrise, sunset, moonrise, moonset, and moon phase at a glance. Save recent locations, find locations using GPS location, and save graphs for later.

Tides have a great influence on the lives of boaters, fishermen, surfers, coastal communities, marine life, and vacationers just to name a few. Directly or indirectly, the great flow of our massive ocean bodies of water impact the daily lives of everyone on this planet.

The cyclical movement of the Earth's tides are caused by a combination of the gravitational forces of the sun and moon as well as the shape of the costal region. Unlike simple tide clocks that you can buy in novelty stores, more accurate tide predictions use special data gathered by instruments located at each tide station. The data from these measurements are used to determine the harmonic components which then feed into the mathematical algorithms which predict tides for the future. The end results are tested for accuracy and adjustments are made as necessary.

Tide Graph has US owned Tide Stations Only. An internet connection is required to get the latest tide graph. - See TideGraph.com for a complete list of stations.

Tap on screen icons, use the search bar or open main menu to find animals, food, rides and attractions – even bathrooms and water fountains on those hot days.

This is a must have for recreational boaters in Florida and snowbirds cruising south for the winter down the ICW. Boating in FL can be frustrating due to no wake zones and limited bridge openings. Limited bridge openings could mean waits of up to an hour or more. This tool will help you to stay informed and plan accordingly.

The app covers all of the waterways in Florida, including the Intracoastal Waterway (ICW), bays, inlets and canals. Also covers key areas such as the Okeechobee Waterway, New River, and more.

Genre: Navigation
Price: $0.99
Release Date: August 9, 2022

The app uses photon accumulation in low-light conditions, so the number of frames per second may be quite low. This behavior is not lag or a bug, but a necessary process that works around the physical limits of a standard smartphone camera.

The final image quality also depends heavily on your specific smartphone model and the amount of available ambient light.

For the app to work correctly, it needs at least a minimal light source, such as a starry sky or moonlight outdoors. In complete darkness, such as an enclosed room without windows, the app will not be able to create an image. Conversely, in daylight or bright light, the screen will turn completely white because the sensor is oversaturated.

Release Date: August 2, 2010

This app puts the Mayan Dreamspell Calendar in your pocket! "13:20:Sync makes it so much easier to understand and integrate the calendar into every day life. Highly recommend it."

The Mayan People have described, in breathtaking precision, the cycles of both the universe and nature around us. They created a harmonic calendar that is synchronized to all those cycles. Following these cycles can help you get a stronger connection with nature around you and become conscious of your essence.

This app provides a simple way to sync along those cycles, to raise our frequency and give us a new lens to view both our day-to-day and planetary events.

- Did you ever realize that our (Gregorian) calendar is not a harmonic calendar?
- Did you know that the moon has 13 (not 12!) orbits around the earth in 1 year?
- Why do we live with this irregular calendar?
- Are you interested in Astrology?

-> All this, and more, is explained carefully in this app. (over 15.000 words on 37 pages) Please note that these text are in English language only.

In the New Time, synchronicity is the norm.

"This app is great, and allows easy manipulation of dates. I spent years in books doing in hours what I can now do in seconds."

For the ones who are already familiar with the Mayan Calendar this app is a handy tool to navigate the cycles, and calculate the Combined Kin for any given combination. Furthermore this app can be of great assistance to teach other people about the 13:20 cycles and is used in teachings around the world.

EZ Celestial Navigation - EZ Celestial LLC

EZ Celestial Navigation
EZ Celestial LLC
Genre: Navigation
Price: $29.99
Release Date: March 3, 2021

Celestial navigation has never been easier! With ezAlmanacOne and a sextant you will be finding your fix like a pro in no time!

ezAlmanacOne is an evolution of the iPad version of ezAlmanac with the modern user interface used in the Windows 10 version of ezAlmanac. All of the features of ezAlmanac plus new features including:

- Universal app runs on iPad, iPhone, iPod touch, and the new MacBook with M1 processor.
- Supports all device orientations. All screens support zoom and pan.
- Make bearing observations to perform compass checks.
- Archive saved observations and restore observation data from an archive.
- Includes quick start guide, usage examples, and other documentation to learn celestial navigation.
- Print/Output Nautical Almanac pages, observation reports, and other app documentation.

ezAlmanacOne will help you perform celestial navigation exactly as it has been done for hundreds of years. It produces all Nautical Almanac (1960-2059) and Pub. 229 tables exactly as you are used to seeing them in the printed form. All tables can be accessed directly for manual usage if you choose to do so. Since they are produced by the software they support zooming and panning, and you can highlight in the tables to easily find the correct value to use.

Most users, however, will prefer to let ezAlmanacOne do all of the work. Simply enter the basic sight parameters, make and enter your observations, and ezAlmanacOne will do the rest. It performs all of the steps to correct your observation, find GP of the object, do the sight reduction, and plot the LOP. No steps are skipped and all details are shown. Click where the LOPs cross in the plot and you have found your fix!

Besides finding your fix, ezAlmanacOne is one of the best tools available to perform compass checks from a bearing observation of one of the navigational bodies. The compass check function supports checking up to 5 devices from a single bearing observation. ezAlmanacOne will also create a report of your compass check that can be saved as a PDF file or printed for the ships records.

Celestial navigation instructors love ezAlmanacOne because it does celestial navigation exactly as they teach it. Values obtained from the Nautical Almanac and Pub. 229 are clearly identified with an icon of the book. When you press the book icon you are taken to the page that has that value with the row, column and value highlighted. Even when ezAlmanacOne is doing all the work, it can teach you how to do it manually using the books.

For manual celestial navigation you can generate and print Nautical Almanac pages to use as a backup on a passage. You can even print the sight reduction forms and plotting sheets you will need.

ezAlmanacOne performs all astronomical calculations using the NOVAS 3.1 software from the US Naval Observatory (USNO) and a JPL ephemeris that covers the years 1960 through 2059. It also implements WMM-2020, the latest World Magnetic Model software available from NOAA, to compute magnetic declination. Since all calculations are performed in the software, ezAlmanacOne is fully functional with no dependency on the internet.

BlindSquare - MIPsoft Oy

BlindSquare
MIPsoft Oy
Genre: Navigation
Price: $39.99
Release Date: May 21, 2012

BlindSquare is pioneering accessible navigation both indoors and outdoors. Know where you are, know where you're going, travel with confidence.

BlindSquare is a new solution that combines the latest technology to help the blind with their daily lives. It has been developed in collaboration with blind people and carefully field tested. You need either an iPhone or an iPad to get started. It also supports some additional accessories to enhance the experience.

How does it work?

BlindSquare uses GPS and the compass to locate you. It then gathers information about the surrounding environment from FourSquare. BlindSquare has some unique algorithms to decide what information is the most relevant and then speaks it to you with high quality speech synthesis.
“What's the most popular café within 200 meters radius? Where is the post office or the library?”

You can control BlindSquare also through voice commands. The Voice Command feature is a premium service requiring purchase of credits for continuous use. Voice Command Credits are available as an in-app purchase on the App Store.

Using BlindSquare as a GPS solution:

When you start the app, it will start telling you the interesting places and street crossings around you. By changing the radius, you can limit the area you are interested in. You can also search by search term or by category. You can select an interesting place from the search results and perform the following tasks:

1) Get contact info (address, phone number)
2) Open twitter feed or restaurant menu (if provided)
3) Make a phone call
4) Start tracking the place (BlindSquare will assist you by repeating the distance and the clock face direction)
5) Start your favourite navigator for turn-by-turn instructions (TomTom, Navigon or Apple Maps)

BlindSquare is aware of when you travel by car, bus or train and starts to report interesting places in front of you (for example, the next stops) and street crossings when you are passing them.

You can also save your own private places to iCloud so they will be found with your every device.

Using BlindSquare as a Foursquare client:

If you like to play Foursquare, you can do the following with BlindSquare:

1) Get a list of nearby FourSquare venues
2) When you are in a place, you can check in by shaking your device
3) Do a check in with commenting and twitter/facebook sharing
4) Correct the location of the place

BlindSquare supports the following languages: English, Arabic, Bulgarian, Croatian, Czech, Danish, Dutch, Estonian, Finnish, French, German, Greek, Hebrew, Hungarian, Italian, Japanese, Korean (South Korea), Norwegian, Polish, Portugues, Romanian, Russian, Spanish, Swedish and Turkish.

VoiceOver usage is supported but it also includes higher quality additional speech synthesis by Acapela Text-To-Speech from Acapela Group.

Instructions in English: https://www.blindsquare.com/user-guide/ and https://www.blindsquare.com/faq/

Please note: This app retrieves data in real time from Foursquare and Open Street Map. Use of a flat rate data plan is highly recommended.

Continued use of GPS running in the background can dramatically decrease battery life.

Having only been released in May 2012, BlindSquare has already received several prizes and awards:

- GSMA: Global Mobile Awards 2013, Best Mobile Health Product or Service
- Apps4Finland 2012
- OpenCities App Challenge 2012
- The Finnish Information Processing Association: Best Product 2012

Please note: To use BlindSquare, your iCloud account has to be active so BlindSquare can access it to save your settings and places.

Continued use of GPS running in the background can dramatically decrease battery life.

Pro Compass for Watch - Craig Hunter

Pro Compass for Watch
Craig Hunter
Genre: Navigation
Price: $1.99
Release Date: September 27, 2019

The legendary iOS compass app is now available for Apple Watch! Pro Compass replicates the look and feel of classic pocket compass hardware in use since the 1800s. The app uses advanced graphics technologies (normally reserved for games) to render 3D floating compass hardware for realistic operation.

Pro Compass offers true and magnetic compass modes using a damped rosette-style compass ring. Local sun and moon position are shown on the compass ring and continually updated. Pro Compass also displays location and altitude, and contains a built-in two-axis inclinometer that drives two independent bubble levels and a bullseye level.

New in Pro Compass for Watch version 2 is a map screen and waypoint manager. You can add waypoints on the map or at your current location, and view waypoints on the compass ring to visualize their bearing from your current location.

Pro Compass has settings for compass mode (true or magnetic, degrees or mils), distance/altitude units (feet or meters), and position format (decimal degrees, degrees-minutes-seconds, MGRS, USNG, UTM, UTM-B, and Maidenhead Locator System). The app has six color schemes, including two night vision modes - midnight red and luminescent green.

Pro Compass for Watch is recommended for Apple Watch Series 5 and later (including Ultra). Apple Watch Series 4 and older do not have a compass sensor and will not show compass data. On older devices, the app uses the device's gyro sensor to measure rotation. You can twist the watch's digital crown to adjust and calibrate the gyro to the sun position, moon position, or a known bearing. Using these references, the "gyro compass" is able to give bearing. The calibration can be repeated as often as desired to give accurate results.

Accuracy note: Pro Compass reports accuracy from the magnetometer sensor in your watch. To improve results, operate Pro Compass away from magnets, electronics, or sources of electro-magnetic interference, including car dashboards, aircraft cockpits, metal structures, and other devices.

Developer note: like all our apps, we plan to continually improve and evolve Pro Compass for Watch. Please contact us with feature requests, suggestions, and general feedback. We'd love to hear what you're doing with the app!

Rate Of Climb Industries
Genre: Navigation
Price: $3.99
Release Date: May 28, 2015

Instant and location accurate Density Altitude calculator/instrument app for iPhone and iPad that also finds relative air density (RAD), altimeter setting, relative humidity, specific humidity (grains/lb) and more. Super useful for pilots, especially in the backcountry. Many other uses for engine tuning, racing, sports, etc.

* Seamlessly integrates weather data, GPS and your phone's onboard barometer to quickly and accurately calculate your density altitude, altimeter setting, relative air density, and more.

* Takes humidity into account in all calculations, making it more accurate than the typical dry bulb approximation formula used by AWOS/ASOS, etc.

* Works anywhere. Great without cellular connection as well, which makes it all the more useful in the backcountry and far away from ASOS/AWOS stations.

* Location Search: Find atmospheric data (Density Altitude, etc.) at any point on Earth, from anywhere!

Data Sensed and Calculated (all calculated with humidity):

* Density Altitude
* GPS Altitude
* Temperature
* Altimeter Setting
* Absolute Pressure
* Dew Point
* Relative Humidity
* Specific Humidity (grains/pound)
* Air Density
* Relative Air Density (RAD)
* Dyno Correction

The quickest way to get your Density Altitude! On the iPhone 6/6+ and newer iPads, it will use the built-in barometer and GPS. If you're in cell range, you don't need to supply any data. If you're out of cell range, all you need to supply is the outside air temperature. Designed not to need an internet connection, so it will work anytime and anywhere you need it.

Great tool for pilots, drag racers, engine tuners, golfers, or anyone who needs to conveniently find their Density Altitude, Altimeter Setting, Relative Aid Density (RAD), Specific Humidity or Absolute Pressure.

5 Stars by Rawd
"Great My 79 Firebird speedo only goes to 140 kmh. ;). This worked perfectly."

5 Stars
"Within 1 mile per hour +/- Great Job!"

SpeedBox was one of the very early Speedometer Apps for the iPhone. Take advantage of my experience and the refined algorithms that can get a much greater accuracy from the iPhone then a lot of other apps. I regularly update my application to make it even more accurate and usable.

Users have already used our application to verify the accuracy of their car's speedometer or they tried measuring the speed they achieved while skiing. Can you come up with more ideas? How about measuring the speed of the airplane you travel with?

USAGE NOTES
========================
The "GPS strength" indicator in the top left corner should display a green dot. You can tap this indicator to display the current GPS accuracy.

Please allow the application up to a minute to find enough satellites to work correctly.

If you get a message to enable GSP, please go to ”Settings > General > Location Services“ on your iPhone and check if the little switch is set to "On" for Speed Box as well as for "Location Services" in general.

ATTENTION iPod touch users! Unfortunately this app doesn't work very well on the iPod touch and the iPad WiFI (without 3G) since these devices are missing a GPS!

FEEDBACK
========================
