I like utilitarian apps, so this was right up my alley. It is undoubtedly the best strobe light app out there. The adjustable speed feature is really nice, and it is also very simple to use. The only problem I have, and the reason it got 4 stars, is that the light quit flashing when your phone goes to sleep. I used this to slow down traffic one night at the scene of an accident, and this was a real pain. Otherwise, love the app!!!

It works and works great, just what I needed. I would have given five stars if, like some others said, it would continue while having your phone screen off. But still a great app and for sure worth getting!

This strobe light works the best out of the ones I have tried. One thing I did to test the strobe effect is waved my hand behind the phone to see if I got the motion stutter effect and this was the only strobe that looked like a real strobe light was on.It would be nice if it had a music strobe feature (strobe music) and if on/off was a separate button from the strobe slider.

Good flash light and this is the only app I've seen that actually does a real strobe effect. Most apps to a slow flash even though they consider it fast. Turn out the lights and set the fast setting with this and you have a real strobe light. For free too. 5 stars.
