User Reviews

Overall, users value the app for easy, on-device measurements that help tune turntable speed without extra gear, but frequent price and usability hurdles—limited trial, upgrade prompts, and occasional reliability issues—limit its appeal. The tool is appreciated by audiophiles for its focused features, yet the cost and inconsistent accuracy deter broad adoption.

Pros

Easy to use and intuitive interface.
Quick, hardware-free measurements with just a phone (no strobe needed).
Helpful design touches like the tape-roll measurement method and rotation lock.
Helps diagnose and correct turntable speed and pitch issues, improving playback.
Appeals to audiophiles with a focused, specialized feature set.

Cons

Price is too high; the $15 full version is considered overpriced.
Free trial is painfully short: only 10 tests before upgrading.
Aggressive upgrade prompts and intrusive popups disrupt the workflow.
Bugs after upgrading: history/results may not save or the app locks.
Questions about accuracy and calibration; measurements may be unreliable or incomplete.

Recent reviews

I’ve been using this app for years, and I’m absolutely loving it. Easy to use, and considering that it’s a phone app there’s nothing that comes close to it. I just wanted to express my gratitude to the man who developed this real audiophile-oriented app. Thank you very much 🙏🙏🙏

Replaced my Marantz TT 42 belt and it played slow. Had no idea what to do but read about this app and happened to have the teeniest flat head screwdriver and now the music sounds great.
