App project draft travel alarm

app name: travel alarm

feature: wake you up when you arrived destination.

motivation: I slept over in train to home and missed the station that I need to get off. So I need to go back to the opposite direction.

Target user: People who use public transportation and wants to concentrate to some work or sleep.

Algorithm: based on estimated arrival time, wake up user. Or based on GPS information, wake up when you arrived destination.(or close by) Using GPS will take up lot of battery, so mix it together or some other solution will needed.

Google map: interaction with google map is desirable. Other wise, put google map into app. Or user manually put destination and estimated arrival time.
