Ratings and reviews

The name says it, it's really a Cool Flashlight, small in size, no ads, with just required features.

very poor app. you have to switch it on at least 10 times in a minutes as it switch off again and again...

This is the best flashlight I ever use. Small in size but very quick respond and no advertisement. I love it.
