Good but major un-functional low side of piano

This app is great, it is very very accurate with my piano but sadly the tuner cannot track anything lower than A2 of my piano. A little bit too for the high notes you only get to see like 1.5 secs of how much is out of tuned so you can’t really see it for sure. All I need out of all this is the A2 and lower fixed pls. I would pay if this is on the paid app. Plz fix and I will consider upgrading.

Developer Response ,

Thank you for the review. Please check our other app, Bass Tuner BT1 that is optimised for tuning low frequencies.

Great app but just a few changes need to be made

This app is great but I wish I could adjust to each instrument and know whether I am tune a concert pitch instrument our a Bb instrument. Because I am a trumpet player and when I play a G it shows that it is an F on the tuner, and no this is not an intonation problem because I can tunes and it will still be wrong. I guess what I am saying is please make it to where you can adjust to a different instrument.

Suggestion :)

It would be cool if you could deflect certain notes to where it actually doesn’t turn green, I would use this personally to practice free styling singing while in key and I would happily pay for that feature!
