Ratings and reviews

This seems to be a pretty good app, I think really the biggest limitation is our phones camera, and the measuring apparatus. There are no ads :) . I do suggest adding a bit more UI to the screen where it measures the hz and rpm, give it an indicator of when its processing and when it has come to a result, or something like that anyway, maybe a reset button? Anyway, its cool and simple.

I needed to see how fast several ceiling fans were rotating before and after I replaced the capacitors which control their speed. This app worked perfectly. It's not pretty or flashy, but it works. I put my phone on a table beneath the ceiling fans and opened the app and measured for 15 seconds. It gave me accurate rpms and proved the new caps were working.

Scam app! Impossible to use this app. Ads fill half the screen and there's no button to start the app, only buttons on how to use, rate, and share. Don't waste your time!
