Much like Type n Walk shows you what's on the other side of your phone while you text, MegaReader creates a transparent backdrop for ebooks. Let's read A Tree Grows In Brooklyn in front of a tree growing in Brooklyn!
It's the first heads-up display of its kind for an iOS ebook app, and works on any iOS device with a camera that runs version 4.0 or higher. You can only read DRM-free books, unfortunately, which means that MegaReader's stash of 1.8 million free books is primarily classics and indies. But! They're classics and indies you can read on the go without bumping into things. Which, for a two dollar app, isn't half bad.
$2, but still probably a bad idea in general.
Twimon: Kat, I choose you!
This Twitter app is so bonkers, I don't even know where to begin. *deep breath* Ok, so it has MONSTERS and like POKEMON, your monsters ATTACK your followers' monsters and...oh god, I miss the days of Twitter SMS.
The app itself is a free download, but you can pay for monster eggs inside the game for a buck each. It's your duty to raise your egg, nurturing it by tapping on it or tweeting. Once the monster pops out of the egg, it starts attacking areas within your location (via Google Maps, naturally), every five minutes. If your monster gets attacked though, be prepared for some tears and lost points.
Oh, and you can tweet inane commentary about your breakfast cereals.
Free with in app purchases.
Time Shutter: A free app that puts historical San Francisco in your pocket, in the form of a geo-enabled map, historic photos you can overlay on modern SF, and more. Free! History! It's cool!
OneNote: Microsoft is crrraaaazy about the cloud these days, and they're using OneNote Mobile, a free companion app to their popular lists and notes software, to get iPhone users on board. Naturally, it syncs seamlessly with Windows Live SkyDrive.
The OneNote iPhone app, free for a limited time, lets you make lists and take notes that can include text, photos, checkboxes and bullet points which can be organized into various color-coded sections. And thanks to Windows Live, OneNote possesses the one crucial note-taking feature: syncing. With a Windows Live ID, your notes get stored in the cloud, allowing you to get at 'em from the PC software, a web app, or the iOS or Windows Phone 7 apps. COOL! And perhaps this means we'll be seeing other Office apps in the App Store soon.
Trickle: A Giz App of the Day. Pretty simple: Designed for in-dock usage, Trickle shows you your Tweets one at a time, as they come. You can tap one of two buttons to retweet or favorite a tweet, and you can swipe back through your timeline manually, but that's about it. Perhaps not ideal for Twittermaniacs who follow people by the hundreds, but for monitoring a well-maintained list of followers (or even a single source) it's pretty clever. And better than staring at your battery crawl up while your iPhone's in the dock, in any event. $1
PBS: While Angry Birds may boost your self-esteem, it does not necessarily enrich your mind. The new iPhone app from PBS makes dozens of full episodes of shows like NOVA, Nature, and yes Antiques Roadshow available on your phone. Free.
Precorder: A Giz App of the Day. Precorder's a replacement for your iPhone's built in video-shooting app. It perpetually saves a few seconds of video before you actually hit the record button, so if you're filming a specific action, as opposed to a general scene, you can wait for the thing, whatever that may be, to happen and then add a few seconds of build-up after the fact. Say you're waiting for your dog to do something cute. You don't have to film him for minutes at a time and then whittle down the footage; you can just point your iPhone at him, wait for him to lick his balls, and then hit record. Precorder will back things up a and give you the previous 5 or 6 seconds of footage. $1.
Google Places: A Giz App of the Day. Once upon a time, Google tried to buy the restaurant-rating site Yelp. When that fell through, they decided they'd just build their own version. Google Places for iPhone, which includes Google's new restaurant recommendation engine, Hotpot, is a key piece of that puzzle, a polished resource for finding nearby restaurants, bars, and cafes when people are out and about. Places has been on Android for a minute now, natch, but the iPhone version opens the service up to tons more users (and soon, with the Verizon iPhone, tons and tons of more users). Free.
