True Note for Android

Does not produce correct frequency, at least with an Android 13.

This app is great to ensure that my 1975 Empire 598 III Troubadour turntable is spinning at the proper speed. Since there is already a strobe disc built-in to the center portion of the platter for both 45rpm and 33 1/3rpm, the 60hz strobe light setting within this app lets me adjust the rotational speed properly until it is locked-in completely for proper playback. Other apps will give you ballpark figures, but only a strobe will give you a proper reading every time. Highly recommend to turntable owners that already own strobe discs or platters.

This was the only app I found that actually helped me fix my turntable. It was straightforward and quick to use. I wish it included a 45 rpm strobe disc as well, but I was able to find one online.

I didn’t try their strobe disc, but the strobe matched up accurately with the one on my technics turntable. Pretty cool!

Thank you for this very simple and useful app. My turntable did not come with a built in strobe, but did include speed control. I purchased a stroboscopic disc but using it with household lamps was fine but not as simple as I would have hoped. After trying a few other strobe apps, which gave varied results, I have found this app works the best. Simple and effective, and appears to work on both 50 and 60 htz settings. Music sounds great. Thank you.
