Description
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 EULA ( http://cygery.com/wordpress/apps/legal/eula/lichtwecker/ ). 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.
Recent changes: v0.0.4: Bugfixes: - bug 0000006: Sliders for start/end brightness and alarm duration have no effect - bug 0000007: activation is just a black screen, no debug information (workaround implemented)

Comments on Lichtwecker (dawn simulator) for Android
★★★★★
Works This app works just fine for my purposes. I actually wake up when I need to, which is hard to do in the Pacific Northwest during the darkest,days of winter. I would love the ability to set and save different alarm presets. But that's the only thing that I think is missing. I'm not having the lock screen trouble that others are reporting.

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.
★★☆☆☆
Disappointing It didn't unlock my screen, so when I woke up and pressed the power button to unlock, I was blasted with the full brightness of the screen at the end of the alarm.
★★☆☆☆
Doesn't work I've never been able to get this to work on my sony xperia z3 compact. It says it's set but never goes off/starts, stating that alarm was deactivated due to the phone being active, which is never the case. I've tried all the different options (changing lighting settings, duration, start & end time, setting it to go off a few minutes time, & several hours time) & still nothing. Very disappointing.
