Strobo RPM Hz Light Free for Android
Doesn't work at all on Huawei P9 lite
Dose not work on CAT S60
Not working with Samsung galaxy edge 7
Thank God someone finally made this app.
Did not run at all
Doesnt do anything
Didn't do she it.
Useless
Garbage! No instructions on how to use it; though I did figure it out. It couldn't even read a simple 200 RPM drill press spindle. I got an error message when I pressed 'calibrate' and the message was in Portuguese. If you don't hold your finger just right when you press the lower buttons, you'll get the blasted ad being displayed at the time. How hard can it be to write a simple RPM counter? If I knew how to program Android phones I'd write my own; but I don't need that distraction from other projects.
This app work 1 out of 20 tries. On a fresh out of the box brand new phone.
Did nothing but turn on the LED on my galaxy s8.
Krap does not work
No abusive permissions. It works as described. I don't know about its accuracy but it gives you strobe lights in different ranges. The SOS function is useful; it would be nice if it was a widget.
I have to first press the flash button then wait for the LED to come on solid before pressing the green dot or it doesn't work.
I would like to see an option to flash the screen (and select the color(s) too!) instead of the camera flash, but it is a good app.
The calibrate feature needs refinement, and quick tutorial on launch will make it 5 star app
frequency does not work
Only strobes for a few seconds.
Crap
Screen appears with controls but no light ever works.

Don't work on nexus 6p....
Cool idea. Didn't work on Galaxy Note 4.
Tried to measure turntable speed with 60hz. Wasn't possible since no constant 60hz pulses. Not sure if app or phone is the problem. . Edit : after dev replied I tried again. Still no constant 60hz flashes. I assume it is the phone.
Great
Muito bom para uso industrial! Faz do celular uma ótima ferramenta de inspeção! Parabéns!

Works well enough once controls figured out to set my 78 rpm phonograph with a test against actual stroboscope was spot on. Much better than using an old style table lamp bulb for 60Hz. Tested on a Samsung galaxy grand prime. Only down side is screen controls are touchy.
