Whirlometer

Needed to adjust my old Technics SL-5 direct drive player. The compact design does not allow to put the iphone on the deck. So taking short videos is perfect for a (rough) calibration. Of course it does not allow to check if the speed is stable but it gives a good measure of the average speed.

What a clever way to measure the speed. Much better than the gyroscope apps. Gold medal deserved!

I thought my Audio Texhnica LP60 was running a bit fast but it doesn’t have a strobe meter to check. This no frills app is pretty simple to use and verified that it was running too fast on 33 and 45RPM. After lots of tweaking with a screwdriver underneath the turntable, I checked with the app and against streaming versions of songs and I got it at the right speed. Hopefully I won’t need to check again for a long time. Well done, developers.

I tested this against a fancy strobe&disc combo. This worked perfectly and yeilded the same result. But without the extra hardware. Nice.

Took a little bit to figure out how it works. But found my table was a wee fast. I could hear it was off when I tried to play guitar along with a record. It said it was 33.7 rpm’s . After adjustment and checking with this app , it now says 33.3 rpms. And it does sound in tune with my guitar now. Great !

I took a chance on this app because I could hear that my records were off pitch. It took some getting used to how it works, but my records sound the way they should. Thanks to the developer!

I was going nuts using a digital recording as a reference with no avail. Thanks to this smart app the paper on my TT is perfectly tuned.

I was so surprised at how accurate this was. I’d normally use other apps that require putting your phone on the plate, but those usually cost money or scam you with in-app purchases. I’m go glad this app was free! I was able to get my player spinning at exactly 33.3 rpm, and I was also able to adjust my 45 rpm setting!

My TT was almost unusable, due to my records always playing faster and higher pitched. I was skeptical at first, but after using the app I found out that it was spinning at 34.8rpm! After a couple quick tweaks I got the speed dialed in to 33.3rpm and since then my TT has never seen so much use. Thank you to the brilliant devs who put this together!

TT was running too fast. Used this app to lock it in with no problem. Very accurate results.
