★★★★★ Lee · Mar 11, 2023

Great for tuning various instruments. The decimal placement gives very good accuracy as well.

★☆☆☆☆ Tres Longwell · Sep 27, 2025

Not really audible below 100 HZ but what's worse the up and down fine tuner does nothing only the slider changes the pitch, and you cannot zero in on a frequency

★☆☆☆☆ Juan Carlos Kruz · May 19, 2026

Does not work at all. I was so excited to see it in action. Gemini has misled me again to another 4th world app that markets a false product. Yay🤦‍♂️
