This simple app is designed to help you tune your cello by ear. Touch a string to let the note ring out as you tune up. You can also switch to a pure "tuning fork" tone, pitched an octave above.

Tap to the left of the strings to stop the tone.

What’s New

Version 1.4

Improved icon and text positioning for different screen sizes. You can now tap the left side of the screen to stop the sound.

I thought that with this app when I played my string it would tell me wether it was sharp or flat, but instead it just plays the pitch you need to get to. I don't know about anyone else, but I'm not good at tuning from just listening. Maybe this app will be good for others, but it just doesn't work for me.

Make one small modification

This app works perfectly. No glitches, adds. It's perfect!...except one small thing. This tuner is an entire note off. Instead of giving us a C, g, d and a, you are giving us a b, f, c, and g. I suggest that you make a small tweet to make this app even better:)
