ptAlert

An app that wakes you up when you have reached your destination.

When you are traveling with public transport, you often would like to continue sleeping.
But you are afraid that you will not wake up when you have reached your destination.
But now you can use ptAlert, and sleep easily. 
Using the map functionality, add a destination to the ptAlert app. 
Start the alert, and ptAlert wakes you up when you are near to your destination.
ptAlert uses various sounds, but can also vibrate your phone without sound.
