Marco Arment, creator of Instapaper and The Magazine, has just released Bugshot for the iPhone and iPad. It’s a small, highly focused app that lets you quickly, easy mark up images with arrows and boxes. The intended purpose is to take screenshots and callout graphical glitches, typos, and any other visible errors, and then report them back to the developer and/or designer so they can get fixed. Here’s how Arment describes is on Marco.org:

Bugshot’s sole purpose is dealing with those screenshots better: being a home for them, making it easier to find them (rather than browsing your entire Camera Roll, interspersed with photos), and making it fast and easy to draw big orange annotations on them so it’s clear what needs attention.

In a double dose of irony, the Bugshot icon is itself the result of an early Core Graphics glitch, and the grid Arment superimposes on screenshots doesn’t properly fill the screen in landscape mode. The former isn’t going anywhere, but the latter will be fixed in the upcoming Bugshot 1.0.1 update.

Using Bugshot is straightforward. On launch, it accesses the camera roll and ingests all the screenshots you’ve taken on your iPhone or iPad, and it’ll actively monitor for new ones and add them while the app is running as well (in case you want to Bugshot the Bugshot). Scrolling performance in the photo picker still seems a bit rough, and there’s no status bar (or emulation, Twitterrific 5-style) to tap to get taken back to the top. However, the way it shows landscape screenshots in landscape is clever.

Tap the screenshot you want to annotate and it zooms up to fill the screen, including a delightful rotation if its in a different orientation. An iOS 7-style menu bar sits on top that you can use to cancel out, switch between arrow and box drawing modes, and share. You can show or hide it with a tap. When it’s shown, a clever grid overlay covers the screenshot so, if you get distracted and come back, you won’t mistakenly think you’re looking at the actual app and not just a sceenshot. While the screenshot zooms in to fill the screen, if you cancel out it doesn’t zoom back to its place on the image grid. It zooms generically back out to the center of the screen and fades away. It’s a small thing, but it breaks the symmetry of the animation and the spatiality of the app, especially considering it’s otherwise spot-on iOS 7 look and feel. That might be too much work to implement on the current iOS 6 version, however.

Once you have your screenshot, just tap and drag to draw arrows and boxes to your heart’s – or bug’s – content. You can touch, hold, and move arrows and boxes around. It’s non-destructive for as long as you’re still working on an image, so you can layer elements one on top of the other and later un-layer them. However, you can’t rotate or scale them. Once an element is drawn, it’s done. Unfortunately, you don’t seem to be able to undo or delete them either, so if you make frequent mistakes – like I do – you’re left to cancel the entire markup and start over. Maybe a shake-to-undo and toss-offscreen to delete function would work here? Also, bigger arrows and boxes come with thicker heads and lines, so if you want to connect something across the screen, you’re getting a fat element, not just a long one. At smaller sizes this type of scaling makes a ton of sense. At larger sizes, locking the thickness and simply extending the shape might work better lest they blot out the screen.

There’s no ability to add text to the markup yet, which is a traditional feature in apps like Bugshot. Hopefully that gets added in the future, but in the meantime you can add a note to the email or message you send with the bugshot.

Speaking of which, when you’re done marking up the screenshot, tap the action button to send the final image by Mail, Messages, Twitter, or Facebook, or save it to the Camera Roll, assign it to a Contact, Copy it to the clipboard, or Print it.

That’s it. In, (mark)up, out. Like Napkin for OS X and Skitch, the utility of Bugshot is in its speed.

Thanks to its look, Bugshot feels right at home on iOS 7 already (and performs, perhaps, even better there than it does on older versions). So if you’re working on a new app or update, or helping beta test one, Bugshot could come in really handy. Hell, if you have any picture you want to quickly, easily add orange/red arrows and boxes to, Bugshot should be your go to (insert your own celebrity candid jokes here).

Arment called Bugshot a “few days project” on Twitter. What Arment can achieve in a few days, in terms of functionality and polish, focus and restraint, is a testament to his skill in craft. If he has a few more days to spare, and can iron out

It’s that time again, the time of the week when the iMore team shares with you some of their most used apps from the past seven days. This week we’ve got a good spread, with a few games partnered by a couple of travel tools, a note taking app, a gaming tool and a great app for getting video from your iPhone to the TV. Let’s take a look!

Warhammer Quest – Joseph Keller

Warhammer Quest is a top-down, turn-based dungeon crawler taking place in the Warhammer Fantasy setting. You control a party of adventurers traversing dungeons and caves, fighting monsters and collecting loot along the way. You take a turn moving each of your adventurers, either advancing them through the area or attacking enemies. Once a party member attacks, they can’t move any more that turn. Move through the dungeon until it is clear to collect your reward. Each party member has different abilities to aid in the adventure. Warriors are great with swords, axes and hammers, while wizards use different spells to help allys and defeat enemies. Use the map view to travel to different dungeons and towns. Towns let you buy new items, along with selling those that you find on your travels. You can also find different quests in towns, as well as level up your party members after they gain enough experience. If you’re a fan of Warhammer Fantasy or dungeon crawlers in general, Warhammer Quest is worth a look.

Zumba Dance – Michelle Haag

I’ve wanted to try Zumba for a long time now, but classes are intimidating and I’ve never gotten around to buying the game for our Wii, so when I saw that Majestic Entertainment had released the Zumba game for iPad, I was super excited! For a fraction of the cost of the same game for Wii or Xbox 360, you can get Zumba on your iPad and take it with you wherever you go. Featuring superstar Zumba instructors Beto Perez, Gina Grant, and Kass Martin as well as chart topping hits and Zumba original tracks, you can follow along with pre-programmed classes or create your own workout with combinations of routines. Motion tracking technology ensures you get the most out of your workout, and you will stay motivated with the Progress Tracker that helps you create fitness goals and tracks your calorie burn. This game is suitable for everyone from beginners to advanced users of all ages. The basic game is $4.99 which will give you a taste of Zumba so you can decide if you like it and will stick with it. You can buy additional classes via in-app purchase.

Teenage Mutant Ninja Turtles – Rooftop Run – Chris Parsons

The Teenage Mutant Ninja Turtles are back and they’re totally awesome, dude! Well, that’s according to my 9 year old son who has taken to playing the rooftop run game starring them. Having played a bit of the game myself, I can say it’s certainly a bit of fun for adults and children alike though some adults may find the graphics a little on the subpar side. Kids however don’t really care about that stuff and in this case TMNT: Rooftop Run is a pretty decent pick for them and it’s available for free. Watch those in-app purchases though. The idea is to run across rooftops to collect coins and beat up bad guys but your bank account might end up with far fewer coins should someone grab that $50 level-up I saw available for purchase.

Air Video – Rene Ritchie

It’s that time of year again – the summer holidays where I end up visiting family members who still haven’t joined the HDTV age. That’s right, they’re still using the giant CRT screen with nothing by way of inputs other than coaxial cable, RCA jacks, and a dream. Since I pretty much live off streaming to Apple TV, and that requires HDMI, it’s difficult to share the movies and TV shows I want to share with them.

Enter Air Video. It’s an iOS app you buy and run on your iPhone, iPod touch, or iPad, as well as a server app you run on your computer. What Air Video does so well is take any video file you have on your computer, transcode it on the fly, and play it on your iPhone, iPod touch, or iPad. MKV, AVI, Xvid, X264, it really doesn’t care. It just plays them. If you have a modern HDTV with an Apple TV, it can AirPlay right to it, so you’re good to just load and go.

If you have an older TV, however, you need to get a little more creative. Here’s what I did: I took an old iPod touch, an old Apple Dock to video cable, loaded Air Video on the iPod touch, plugged the cable between the iPod touch and old TV, and that’s it.

Sure, you have to get up and manually choose what you want to play on the iPod touch – there’s no remote – but that’s a small price to pay for getting your new video on an old TV.

Air Video can even handle DRM’d iTunes video – which most of mine is now – by punting it to Safari on the iOS device. As long as you’re logged into your iTunes account, it almost always works great. Well, except for that retro 4:3 aspect ratio, but vacationers can’t be choosers…

Travel List – Richard Devine

I’d forget my head if it weren’t firmly attached to my shoulders, and so when I’m packing for a trip I need to keep track of what I need to pack, and what I have actually packed. Since I also lose pieces of paper with lists on, an iOS app is a much better solution for me. Travel List is an extremely simple app, that looks great, and helps you keep track of what you’re packing.

You create a list by trip, and then pre-built into the app is a huge list of items in different categories that you might need to pack. If it’s not there, not a problem, just add it in yourself into the relevant category or create a new one. You also get to add quantities of each item, set reminders for items and on the iPhone, add your trip itinerary too. It really does cover all the bases. Sometimes, it’s the simplest apps that do the best job, and Travel List is one of those.
