Alarm Me is a location based alarm that can be used in a number of different ways. It can tell you when you have reached a certain location such as a train station or a bus stop, remind you when you are near a supermarket to pick up some milk or be used as an alarm clock to wake you at different times based on where you are.
To save battery power and unwanted alarms you can set alarms to only trigger at certain times and not to trigger at all if you arrive somewhere first. For example you can set an alarm to sound if you arrive at your train station between 10 pm and midnight on a weekday but to turn off if you arrive home before that.
Some sample uses:-
To alert you just before you arrive at your train station or bus stop.
To remind you to pick up bread or milk when you are near a supermarket.
As an alarm clock that will ring at different time depending on where you are.
To remind you you should be somewhere else (e.g. if you are still at home when you should be picking the kids up from school)
