[iPhone God App] It was found using the Spottizmo! actually

Spottizmo! is a battery friendly GPS logger application. It uses minimal power to run, allowing you to keep a record of where you've been while still using your phone normally.

Feature
- per day log view
- adjustable GPS accuracy
- import check-ins from foursquare/Facebook
- geotag photos
- wireless collaboration with iPad app Spottizmo! PhotoMapper
- export data to other apps
- send data via mail
- run in background

Notes
- In order to keep battery usage at a minimum, it only checks location intermittently, and as such, it isn't made to keep exact records of where you've been like other GPS applications. Use it instead to get a general idea.
- Excessive use of "HD Tracking" leads to dramatic battery consumption by GPS.
