If your turntable isn't running at the right speed, simply follow the manufacturer's instructions to adjust the speed, then check again with diese App until just right.  diese App lets you calibrate the speed of your turntable by simply playing a record.  It truly is that simple: pick a song, play it out loud, tap the button. diese App tells you if your turntable is running fast, slow, or perfectly.  I'm not gonna lie to you, if that's your situation then maybe diese App isn't going to be super helpful but hey, who knows maybe you want to double check.  Maybe you're the lucky owner of one of those turntables with the little strobe thingie that already lets you calibrate the speed visually.  I wish I had more to say about it, but the truth is that diese App is a very simple app that does one thing, and it does it very well.  On the other hand if, like me, you didn't think you'd ever need that feature and now realized how strangely complicated it is to get the right RPM set up without it, then this app is for you.  It uses your device's built-in microphone, so you don't need any additional equipment.  It's free, without ads nor limits, so you can keep checking and tweaking as long as you want to.  I hope you enjoy using it as much as I enjoyed making it for you.
