The quickest and most accurate tunwr

I’ve seen hundreds of tuners come and go. This is the quickest to recognize the notes by far.

I like everything about it except for

Can you please remove the “try our ear tuner” as please? I have paid to get rid of ads and this is an ad a d it really ruins the otherwise superbly simple abs effective app.

I’ll come back snd give you the other 3 stars once that button is gone. Add a menu button on the corner snd hide it there.

Thank you!

There are 2 Reasons why I rate this 1 star

First, the bar jumps around like crazy and it still does that when I’m in a quite room.
It gets pretty annoying.
Second, It doesn’t accurately work sometimes. One time I was gonna practice my guitar, and the b string was a little deep. Normally you would turn it higher so it would make a higher sound. Well, the app told me to go even deeper. It does work but it’s like a 25% chance it works like it should.
