Lichtwecker is a simple alarm clock which wakes with the backlight of a smartphone. Via a sequence of adjustable duration, during which the backlight lights up slowly, the awakening can be made more pleasant.

Attention: Consider the terms of usage ( http://cygery.com/apps/lichtwecker/en-eula.txt ). Never rely on getting waked by this application. Always use another alarm clock you can rely on.

Everybody reacts different on ambient lighting. Therefore you should test different settings to find out which suits you best. Generally it's recommended to use this alarm clock in a completely darkened room to avoid disturbing influence of other light sources. The smartphone's position and orientation also have an impact on the functionality. A too close position with the display lighting directly on the eyes might be adverse because you awake on the lowest brightness level. On the other hand, a too great distance might render the application useless (because of the inherent low luminosity of the backlight).

Permissions:
RECEIVE_BOOT_COMPLETED: For reactivation of the alarm after a reboot or to show a notification if the alarm was missed.

Excellent. A notification bar icon would be useful.

Best, best, best dawn simulator Does exactly what it should, let's the screen go completely black (I'm really sensitive to light when I sleep), and is free. Not a ton of frills, but everything it has is awesome.

Doesn't Work Wouldn't override the lock on my Nexus 7. Never could get it to work.

Love love love Simple and exactly what I was looking for. In hopes this will work to keep my 2 yr old in bed. "Stay put til the light comes on". That being said, this would earn 5 stars from me if there were options for the light colors. If I could pick a green light to show it would go with the "green means go" concepts they are learning. Or even a simple picture could appear like a sunshine or something.

Simple and complete I'm so glad to have found this app. So many of the free dawn simulators try to do everything, but this one keeps it simple. It also pops up over my locked screen, which is something the others I tried couldn't manage.

Easy and Effective Love how simple it is to set up, and it works beautifully on my Galaxy tablet. Lets me take my dawn light on travel, and give my 4 yo a gentle wake up without spending a fortune. As a free app it does everything it promised perfectly.
