Keep a NSUserDefaults value to count the run time of the app in your didFinishLaunchingWithOptions or applicationDidBecomeActive method:

int i = [[NSUserDefaults standardUserDefaults] integerForKey:@"usageCount"];
i = i+1;
[[NSUserDefaults standardUserDefaults] setInteger:i forKey:@"usageCount"];
[[NSUserDefaults standardUserDefaults] synchronize];

That really won't work because it doesn't deal with iOS loading and launching your app.

The best you should do is log a timestamp in main but again, this won't include the time it takes iOS to load and launch the app to the point that main is called.

Any timing you do will be from that point forward which may still be useful depending on your goal.
