Works spectacularly well. Though it was slightly laggy, I was actually able to control a station in the game Artemis through my phone. Excellent. And free, for most things someone would want to use this for.

By far, the best ebook reader available for iOS. Very, very glad it was fixed for iOS 5.

An absolutely excellent app for organizing (in my case) schoolwork. It's folder and prioritization systems make it very easy to keep track of things, and it's one of the few apps I have that actually makes good use of badges and notifications.

Having this sort of feedback makes a huge difference when you're watching what you eat. Very easy to use, and very powerful -- particularly when integrated with the iOS health tracking suite.

This app used to work well. Now, half the time, I have no idea what it thinks it's doing. It'll log "turned off" for hours at a time, even when my phone is active. It will tell me my 20 minute bus ride took 4 hours. It seemed to improve at one point, after an update, but now it's worse than ever. It was so good when I first got it that I've kept it on my phone, hoping someone will fix it someday -- but I'm pretty much ready to give up.
