NabIT

Continued use of GPS running in the background can dramatically decrease battery life. If you have no location reminders turned on, NabIT does not run GPS in background.

NabIT lets you make a shopping list that sets off reminders when you are close to a store that has what you want or need.
-Nab things when you are on the go, and avoid making special trips
-NabIT will help you with directions if you are in an unfamiliar area
-Using NabIT is easy - make a list of items you need, like eggs and stores that sell it, and NabIT will remind you when you are nearby
