Comments on Strobe Light – RPM for Android

★★☆☆☆ K F · Jun 10, 2026

Seems like a good idea, but it has so much advertising it is unusable. I will delete and just use the old strobe light.

★☆☆☆☆ TheTrueGamer100 · Dec 23, 2025

I understand that free apps have some form of advertising, that's ok, but this is obscene. Every 2ND time you touch the start button an obnoxious TikTok ad assaults you. Imagine trying to delicately skip (button is tiny, suspiciously so) when IN AN ENGINE BAY MEASURING TIMING. Advise finding an alternative (there are several on this store).

Didn't work for me, my phone was redme note14

★☆☆☆☆ Sebastian Ivulić · Jan 31, 2026

The app is utter trash. Full of adds and can't even start the app.

★☆☆☆☆ Alan Morris · Apr 20, 2026

Need a speed of 33.3rpm to set my phono. 33 is not accurate enough. Uninstalling.
