Sounds like something that would be really useful, haven't seen one like that or heard of one though maybe someone else will know.

I think the best you can do is a battery log, seeing as third party apps can't run in the background. You'd have to check the battery log before and after you used an app to get an idea of which apps use a lot of battery.
