Last stop is a proximity alarm application. Proximity alarms means you get notifications based on your GPS location. They are different from regular alarms because they do not go off at a given time, they go off when you get within range of a particular location.

When you add an alarm you simply set a location, select a radius and then turn the alarm on. Your iPhone will work its magic, using various location services it will follow your location and check to see if and when you get within range of one of your alarms. As soon as you do an alarm goes off to let you know.
