I've submitted an big update for TrackMyPhone. Update includes:
- Brand new display name, app icon, and splash screen
- Much improved tracking. Tracks more often and more accurately, while not destroying battery life
- Will no longer submit duplicate location requests (will not update unless new location is more than 100 meters, looking at user customized options)
- New settings page to clean up the screen
- Retina display graphics
- Map within the app to view current location or the last 10 locations (all locations viewable on web interface)
- Ability to turn on a passkey lock. When enabled, app will prompt for this key to "unlock" the app any time it is accessed. For iPhone 4 users, if an incorrect passkey is entered, the front camera takes a picture of the "culprit" and the photo is uploaded to the server as well as emailed to the address associated with the account.
Should hopefully be approved any day now. The design team that made the icon is also working on a matching web UI, so the whole web interface component of the app is getting a makeover as well.
I'll have promo codes for v1.1 once it goes live.
