The man who brought you Instapaper and The Magazine has a new app out\u2014Bugshot, a $1 offering for iPhone and iPad that lets users quickly and easily annotate screenshots from their iOS device. Just draw an orange arrow or box around the item that needs attention, then share it via Twitter or Facebook. It\u2019s perfect for reporting bugs and errors in those other apps.\nDeus Ex: The Fall\nWant all the creepy conspiracy theorizing of The Da Vinci Code with all the blood and mayhem of most first-person shooter games? Deus Ex: The Fall, a $7 offering for iPhone and iPad, brings you just that. The newest update fine-tunes all sorts of features, making your enemies smarter, increasing your rewards for obtaining objectives, making weapons more accurate, and generally just kicking a little bit more butt.\nEarth From Space\nThis $7 app for iPad actually launched a few weeks back, but we just noticed it and it\u2019s the kind of thing we love: A seemingly endless supply of photos of Earth\u2014its clouds, its continents, its landmarks\u2014as seen from space. Everything\u2019s a little bit cooler when viewed from hundreds of miles above, isn\u2019t it?\nFox Soccer 2 Go\nThis is already one of the best soccer apps out there, letting users watch live and on-demand video of games from the best leagues in the world (though you do have to pay a subscription fee to do so).

Spendee lets you record transactions in real time so that you can see where your money\u2019s going. Users can either opt for the app\u2019s \u201csmart\u201d categories or create their own custom categories of expenses; they can also snap pictures of bills and receipts to better organize their files. Better yet it\u2019s secure, offering PIN code protection so only you know what you\u2019re doing with your money.\nSprinkle Islands\nThis $2 game for iPhone and iPad is a sequel to the popular Sprinkle game of a few years back. In this version, an interplanetary trash hauler accidentally scatters its cargo over the islands of Titan. Your job is to put out the resulting fires while conserving as much water as possible.\nUber\nUber, which lets you hail a ride from your iPhone, has been a hugely popular service in the cities where it\u2019s been allowed to thrive without hassle from authorities. The latest update will prove popular too, letting users agree to split the fare on a single ride. The upside? You can\u2019t get stuck with the bill anymore. The downside? You can\u2019t stick your friend with the bill anymore.\nOther apps of note\nIDrive now lets users back up files with a single touch \u2026 the UpTo calendar app has been relaunched with a redesigned user interface ... the WhatsApp messaging app (pictured) now allows unlimited messaging for $1 a year.
