iOS (Jailbroken): Ever find yourself wondering exactly how much time you waste on Twitter on your iPhone every day? AppAnalytics is a jailbreak app that will tell you all the horrifying details.
AppAnalytics does exactly what you'd expect. It tracks when you use apps, how long you use them for, how many times you launch them, and breaks it down by month. It doesn't do much else, but it's put together well and works as described. If you're trying to save space on your iPhone or you just want to know how you're wasting time, AppAnalytics is a great way to track it all. You can find AppAnalytics in the Big Boss Repository in Cydia for 99¢.
