Remind yourself to do something when you get somewhere!
1. Select a location from map (internet connection required for downloading google maps) and choose a name for it.
(you can add your favorite location to a list to access them later)
2. Choose a text for your reminder
3. Turn on your device's Location and turn on the Reminder service
Now the service will run in the background and remind you when you reach the desired location.
Note that if you turn off your device's location, the service will be shut down.
