I was unable to print off a strobe disc, but I didn’t think that would matter much since I have a nice printed vinyl disc already. However, I was struggling to get my speed set. In the end, my deck was a bit too fast, but reading slow according to the app. I went back to my LED nightlight, and got it dialed in.

What I've been looking for

When I was a kid I had a strobe disc and a neon test light to measure turntable speed. Both lost over the years. This app fills that need quite well.

Not Helpful

Glad it was free because it did not seem to work. Not intuitive. No clear indication if speed was correct. I changed my tat speed drastically with visible change on the display. Glad I had a strobe on my table to set correctly again. Waste of a sheet of paper and time. Disappointing. 😞
