User reviews

Not great

Tuner requires a brief cessation of sound to asses the next note. In other words as you
Play along normally, the tuner will not keep up to monitor your intunation as you play.

Just for trying…

…I paid 3,49 € and in the end it is not useable.
No settings for different tunings or anything else.
Notes below C2 on my piano are hard identified with my IPhone 12. Other apps did. a better job.
I can not recommend this app.
And I want my money back, haha. I never heard that worked…
