I made a free app to calibrate your turntable by simply playing a song
Hey there! I made a little app that lets you to calibrate your turntable by putting on any record and tapping a button. It's called Grooved and it uses your phone's microphone to see how fast your platter is going, almost like magic.

In plain words
Grooved is a free app that calibrates turntables by analyzing audio through a phone's microphone while a record plays. Users simply tap a button to measure platter speed without printing materials or placing their device on the turntable. Built for vinyl enthusiasts, the app contains no ads, subscriptions, or trackers and is available on iOS with an Android version in development.

I have never seen this technology being used before, all other apps require you to either print something and use the camera, or to place your phone on the spinning platter and use the accelerometer. You can grab it on the App Store, and I am working on an Android version I hope to release at some point in June. Would love to hear what you think about it! Ivan_
