User Reviews

Across reviews, most users report crashes, instability, and inaccurate tuning, with limited octaves and questionable pricing. A small number find it occasionally useful when it works, but the majority cite ads, pay-to-unlock models, and poor support. The top pain points are stability, tuning accuracy, and octave limitations, followed by confusing UI and restrictive orientation.

Pros

Helps me tune my piano since my piano tuner retired
One of the better tuners
Very resourceful

Cons

Crashes on launch or shortly after opening
Not accurate or reliable pitch detection
Limited octave range (often 1–2 octaves) unless you pay/unlock
Ads persist or charges occur despite claims of ad removal
Poor UI/UX and navigation (overlapping graphics, no clear instructions, vertical-only orientation)

Recent reviews

I purchased the app and it keeps telling me the octaves are locked. It also still shows ads, even though the ads are supposed to be removed. I contacted the developer and he kept telling me things to try to fix it and none of them worked. I do not recommend this app.
