iOS app on the App Store that sounds an alarm when you reach your destination. Everything runs on the device, with no tracking SDKs.

What I did and how it works
- You choose the destination, set the radius at which you want to be alerted and start the trip: the alarm rings on arrival.
- CoreLocation geofencing.
- AVAudioSession override to guarantee the audible alert.
Results
- ~80 % lower battery use compared with continuous GPS tracking (an estimate based on my own tests).
