The Talking Machine Forum — For All Antique Phonographs & Recordings

I was looking for old techniques to calibrate my RPM's and started looking for a "strobe" app for my phone..
well instead I found an app that literally measures your turtable RPM's by using your smartphone built in sensors ..

worked for me.. thought Id share.

I've been using my Android handheld (Moto X 2nd gen) for a couple of years, to calibrate my various turntables.

The only issue is that the device needs to be used with some kind of non-sliding manner, or it will fly off your turntable!

Best,

RPM app is available for iPhone...
