Hey so I know there a million and a half threads like this but:

I've been studying up on android dev in my rare free time and I really need a project to work on.

I'm pretty good at it (lots of programming experience) but I'm drawing a complete blank as to what I should make.

I was thinking of making a call blocking app because I get a ton of telemarketer calls and all the free apps have severe limitations but I'm not married to it.

I was wondering if anyone has any suggestions. Are there any apps that you would like to see on the market for free (maybe with ads because I'm horribly poor at the moment).

Any suggestions will be appreciated and only horrible ones will be mocked.

Thanks!
