The GeoProximity Alarm Application is like an Alarm Clock where the Alarm is triggered by where you are instead of the Time. You define a geographical alert zone, either circular, rectangular or a polygon. You can configure the alarm associated with the geographic alert zone, selection a sound to play, and if the device is configured to Vibrate it can vibrate, and optionally define SMS messages to be sent(only one SMS message is sent, but you can define multiple addressee with personnel messages which are combined). I am sorry but the SMS is in English only. If the App is placed in the background it will generate notifications which will open the App if you so choose.
