Location Based Alarm app for iPhone and iPad

Continued use of GPS running in the background can dramatically decrease battery life.
This is an amazing app that lets you mark your desired location on the map and the app will notify you when you are near the respective location. You can search your alarm location and set the specified location on the map or you can drag the marker to a new location and set it as a new alarm location . You can specify the radius in from the location in which you want to be notified. After setting these when you will be near the location within the desired radius , BAM ! the alarm will start ringing letting you know that you are near to your location.
