The app should stop in low battery state

[Sergi Quiles Pérez]

This app spends a lot of energy because it keeps the screen on. So you should connect the device to the power charger while using it. In the case you forget to connect it the app could drain the device battery and if you have any alarm set up it won't sound.

In order to prevent this inconvenience I think the app should stop if the battery is below a fixed percentage, i.e. that one when battery icon is showed in red colour.

Thanks for your amazing app! :-)
