I developed this app to prevent slept in on a train. ( well, I guess it's possible only in Japan).
*** English Supported ***
This app will beep only from your headset/earphone. When the headset is plugged in, you can hear the alarm from the headset. When the headset is not plugged, the device will only vibrate. This app will give you relaxed asleep on the train. You don't have to worry about around you.
We will develop extra functions such as turn the alarm on by current location.
If you have any ideas, please mail us via Google Play.
