Comments on Stroboscope Engineer for Android

★★★★★ Zipra · Nov 17, 2021

Impressively accurate strobe light compared to other apps. Perfect to measure electric motor rpm. The only app I've found that can actually measure rpm.

★★★★★ Derrek Leiter · Feb 15, 2022

I am impressed that it can turn the phones led on and off fast enough to measure around 3krpm. Nice!

★★★★★ Zachary Varnum · Dec 7, 2022

Great little app! The strobe light on my turntable burned out and all the lights in my house are LED. I was able to use this app to adjust the speed.

★★★★★ Matt · Jan 26, 2024

Worked well to check my turntable with a strobe disc.

★★★★★ John Price · Aug 25, 2024

Great simple app that gets the job done (but not in sunlight). I used it to check the idle speed on my outboard. A bit of white duct tape on the flywheel and in twilight it worked well. Phone LED's are not bright enough to use in sunlight, and they aren't brief enough flashes to give a true photo grade strobe effect, but it got the job done. Ads are not obtrusive. An improvement would be a bigger frequency slider. It's hard to get the right spot when you are looking at the strobe device.

★★☆☆☆ Aaqil Khan · Oct 30, 2021

Tried it on motor and didn't give accurate speed measurements. I had to borrow an actual stroboscope to do the job.

★☆☆☆☆ little Jim · Jul 28, 2024

Newest version locks up my phone. Complete reboot required. I hate not being sble to revert to previous version of an app!

★☆☆☆☆ James Adams · Mar 22, 2025

Trash. Light doesn't stay on or goes full on when using it. I installed it and shortly uninstalled it.

★☆☆☆☆ Daniel Gunn · Jul 26, 2024

Does this app require reflector tape? I want to use it for checking RPM's on an output shaft on pumps, the range will be 400-1725 ×/-.
