Palerta alerts you when your friends are nearby - smartly, without being annoying about it, and whilst respecting your privacy.
Install it, connect to Facebook - and that's it! Close the app, and forget about it, until you're notified of your friends nearby. Think of it a a service, not an app. But once you have this service, and you see how it works, you'll wonder how you ever lived without it.
Requires Android 2.2 (Froyo) or higher. Notifications take great advantage of the improvements in Android 4.1 (Jelly Bean), but they work fine on earlier versions too.
Palerta will have very little effect on your battery. You won't see it in your battery usage, and you won't see the background service running. It's incredibly lightweight. It uses a location library we wrote and then open-sourced that's being used in some very high-profile apps running and proven already on tens of millions of phones. Beta note: we have seen one or two reports of battery weirdness from custom non-standard Android builds - if you experience this please send the details to firstname.lastname@example.org
- No ability to manually add friends, only automatically. This feature will be completed very soon.
- some of the buttons look a bit weird in pre-4.0 devices. Lots of graphical and layout changes will be fixed soon.
