Einschlafhilfe - Sleep Light

The app helps you fall asleep with a night light in special shades of red and orange, which stimulate melatonin production (sleep hormone). Over the set time, the light becomes darker and darker until it turns off.
In addition, sounds that resemble white noise can be played, which can also help you fall asleep. These include a waterfall, brook noise, rain etc.
The app should be operated on a tablet so that the light is sufficiently strong.
