Keep Me Awake

说明

This is not a watch face. This is written to satisfy a user request, a vibration occurs as soon as your heart rate drops below the threshold which will help you stay awake. (Use with care. It's obviously not a good idea to deprive yourself too long from falling asleep)</p><p></p><p>If you like this app you can support me with a coffee here: http://www.buymeacoffee.com/peterdd</p><p></p><p>
