Great App, lacks Record Keeping

I recently got this app and love it. My only complaint is there doesnt appear to be any way to ask the app to automatically store usage stats for past months, meaning if I want a record of past months I will either need to go in and manually take a screen shot at the end of the billing cycle or I will have to manually reset the counter to zero and turn off the auto reset. This seems like it wouldnt be hard to fix. Please consider adding this feature in future updates.
