Amazed This app is super awesome! I took a long shot and typed rpm calculator into Google Play with what I thought would be a slim chance of finding something useful for calculating platter speed but to my amazement, the was this app and it works absolutely spot on! If you're unsure how to use it, watch the promo video. Thanks dev, a truly useful app!
Gets the Job Done As another reviewer wrote, the app isn't perfect, but it's consistent. For example, my ideal 45rpm was reading between 45.3-6 (it synced almost perfectly with the .mp3 version of the song I used). It might not even be the app's fault; maybe it's just that the hardware between each phone is a little different. Life I said, though: it gets the job done.
Very Useful Works great, but could do with some instructions. eg 1. Place on turntable and run. When screen returns to zero, turn off turntable and the app will settle to the average RPM tested (hopefully 33.3, or whatever) 2. After a few moments of non movement the app will return to "0.0" and be ready to re-test or test other speeds on the turntable. At least that is how it seems to work to me.
Works and works well. I could hear that my vpi turntable speed was off. Happily found this app and tried it out. Seems to be pretty accurate. It's not accurate down to hundredths of a rotation and won't account for the drag of the needle on the record, but man it's just about the easiest and quickest way possible to get you back in the ballpark. Sure beats breakin out the strobe disc or a test record. Many thanks!
This seems to work well. I noticed that the Linn table in the video runs at 34+rpm. That would be consistant with my old Linn. My current table show 33.5rpm which is close enough as I don't have perfect pitch nor does anyone I know. It would be nice if it would log a period of time - like maybe about 5 or 10 minutes to see if there a fluctuations over time. Other wise great app.
Just put your phone on the turntable! Anyone confused by how to use it just read the title! Literally just lay your phone on the turntable and start it up (obviously don't move the tone arm). The display actually rotates to make it readable whilst spinning. Apparently I'm running at 31.7 and 43.5, although I'm wondering if that slight speed reduction is caused by the weight of my (quite heavy) phone? Obviously can't test the speed with a record playing to see if I can hear the difference.
