How can I track app usage? Is there a way to show usage stats for installed applications on my Android phone?  I'd like to know how much I use my apps and if there are any I can get rid of (because I don't use them).
This functionality is already inbuilt into Android.


Open your dailer
Enter *#*#4636#*#*
Select Usage statistics
Sort by Launch Count.


As far as I know these statistics get reset every time you reset your phone. Hope it helps.
