4 Eyes: It's a quick search tool for your iPhone. You know how in your desktop web browser you can program search shortcuts like 'wiki' for a wikipedia search or 'yt' for YouTube, 4eyes captures the same idea. You hit pre-programmed typing shortcuts to search the specific service you want to be searching. No more jumping into Google to click on a Wikipedia, IMDB or Amazon link. The keyboard stays open too so it's always quickfire status. $2
Photovine: Photovine is out of beta and it's more about connecting with people than sharing photos with your friends. The service lets you build a photo collection around an idea or theme using photos submitted by other members of the social network. These collections are called vines and include a caption or theme like mountain hiking. The vine will grow when users begin adding their own photos that contribute to this theme.
Amazon Student: The Amazon Student app will let you trade in the old ones for new swag. While the app won't give you cash for your old copy of Introduction to Forensic Anthropology (ugh), it will give you a price ballpark that you can feed into an Amazon Gift Card, as well as the ability to sell the book to other students signed up to the program. You can even trade-in the old movies and video games you got to distract you from your studies. Free
MiniMash: It takes what songs you have your iDevice, analyzes them, and lets you mash them together quick fast. Only the layout is way stripped down; it looks rather like if wanted to do a set on a Super Nintendo. All the heavy lifting is done in the background-tempo and pitch matching-so that you can create smooth transitions and mixes for most of what you throw at it. You can't scratch, but you do have some of the tools to do more creative, powerful things with your remixes. $2
TableDrum: TableDrum is a drumming app that lets you tap out beats without touching your iOS device. Instead of tapping your screen, you tap an object around you and the app will respond with a drum beat. The developers describe it as an augmented audio application that lets you sync the sound of an external object to a drumbeat. You can tap your finger, slam a door or bang some cans and sync these sounds to the app. $4
Snooze: It's an alarm app that donates a quarter to a non-profit organization (under the LetGive umbrella) every time you hit the snooze button. Think about that, from now on every time you're feeling lazy and can't get out of bed, you're actually helping somebody! The app doesn't force you to donate either, it just makes it a helluva lot easier. Snooze will asks you two times a month if you would like to donate your snooze hits to the non-profit of your choice. It's a great idea but the alarm feature can get buggy sometimes (which uh needs to be fixed) and it's impossible to change charities you want to donate to (or to pick your own).
Lark: It's a companion app to the Lark Un-Alarm Clock, the wristband that vibrates you awake. I've been using it for the past few weeks and it tracks how long you've slept, gives you a sleep quality rating, how many times you woke up, snazzy graphs and more. For numbers obsessed people who wish there were statistics to everything in life, this is absolutely awesome. $130 for the Lark Un-Alarm Clock
