It's not beautiful, but it sure is bright. Brightest Flashlight Free activates your Camera LED (if available) and, of course, your screen, turning your Android into an ultrabright "flashlight."
There's no interface really, and there are no other functions. On one hand, Brightest Flashlight is great because it performs exactly as advertised. On the other hand, however, we wish it had at least some dimming options, or perhaps a blinking S.O.S. feature. One thing it does have, though, is a timer, which can autokill the app after 2 minutes, 10 minutes, or never--your choice.
If you're planning on spelunking with your phone or just want to save cash with some DIY tanning, try Brightest Flashlight Free. Otherwise, you might be better served by a less battery-hungry flashlight app.
