Brightness Widget Galaxy and Supernova Timer, a totally free app by stanlm.
This widget is totally free, no ads, no internet access, just offering a fun way to control your phone's brightness and a quick-set little egg-timer.
What I didn't like about other brightness widgets or timers were they are kind of plain, boring, or take too many taps to set up, so this is killing two birds with one stone.
Here you set your phone's brightness by picking a star. The bigger the star the brighter your screen.
Following an astronomy theme, the grand hulking big stars are your blue hypergiants. Then you got your super giants, main sequences, dwarfs, and for auto-brightness there's the variable star.
A few interesting tidbits about these stars are included, and a fun interface for switching between brightnesses.
Supernova timer is just pick from the time options (5min, 10min, 15min, etc..) and get a notification alert when the time expires. That's it, simple.
Why is it free? Well, there's a lot of brightness widgets and timers out there, and those aren't really very special functions.. I'm just hoping to make space stuff more popular.
