I have over 200 apps on my iPhone 4 (32GB). No one needs that many apps, right? I want to organize my installed apps based on how frequently I use them, and/or how recently I last used them. I could probably take a qualitative, subjective stab at this myself, but I'd like to have some data, just so I don't toss an app that I may have used, but don't remember using. Yeah, I know that deleting isn't forever with apps-- but having geeky data makes me feel good.
So far, I have not found a way to do this. I've seen apps mentioned here on AskDifferent that purport to do such a thing, but have not tried any of them. For some reason, I seem to recall Googling this several months ago, and running across an article describing a way to glean usage information from the backup file(s) that iTunes creates. I can no longer find that article-- not sure if it's gone or if I'm just not using the same search terms as before.
Note that my iPhone is not jailbroken, nor do I wish to jail-break it. I'm not necessarily even interested in an iOS app that gets me this information; I'm simply interested in it any way that it can be had. If that is via Terminal on the desktop, that's fine.
Knowing this kind of usage information would also be objectively useful if I'm trying to implement some kind of app/folder organizational strategy. Otherwise, I'm left to my own intuition about how often I use things, which can be false, or in the least, inefficient.
