Thanks to Philip for an outstanding app. Noticed en entire LP album was a little too high in pitch. Searched for an app to help me fix this issue and then after many tries RPM fixed it, wow thanks again!

App works fine for about 15 seconds then an upgrade screen covers the result.

Very handy app. Like that I can place it atop the record weight and get a reading.

horrid. “10 trial spins” and then eats them up when it’s not even accurate.

It was great up until you get locked out after 10 tries. Not worth my time or money to pay $15 for an upgrade, when the trial itself isn’t long enough.

This app is pretty good, as far as I can tell. It’s really easy to use and doesn’t require as much effort as a stroboscope; just put your phone on a roll of tape above your turntable’s spindle and go. However, it’s extremely limited on the free version, with only 10 tests for 33 RPM and, confusingly, no way to calibrate the app. Like another reviewer said, 10 tests is just enough to potentially get you into trouble if you don’t know what you’re doing. I have no qualms with paying for a good app, but 15 dollars for the full version is way too much for an app I’d rarely use. If you aren’t constantly adjusting the speed on turntables, just print out a stroboscope disk and get a stroboscope app. It takes a little more effort but it’s completely free.

Not accurate. Marketing gets in the way of measurements. Pay me first then do the crap u want to

This works as a ballpark figure for your turntable wow and flutter. Though I don’t know how it can measure these values without a 3khz reference tone. Also, speed is not accurate. It measured 33.44 rpm. My turntable is quartz locked at 33.3333… I used a strobe to verify the speed within .01% accuracy.

I noticed my record player was playing my vinyls about a pitch too low, downloaded this app and proceeded to fine tune it for 30 minutes. You can imagine why 10 trials is too short so I paid for the full version. It definitely got the job done and I will be using it forever, but around 15-20 trials would be much easier in my opinion.
