Sunrise Alarm Clock: Wake up n

Sunrise is an alarm clock, that simulates the sunrise to ensure a soft and natural wake up. Confirmed by several studies, the advantage of a progressive light clock over traditional alarm clocks is the positive effect on stress level, drowsiness and well-being ( source: see below).
Especially early birds and shift workers benefit from this light clock. Test subjects reported that the steady increase of light gave them more energy throughout the day.
In order to optimize the wake up phase, several, thoroughly selected music titles are included to this app.

All features at a glance:
- Progressive increase of light to imitate sunrise
