Zen Tuner

As has already been noted , it will not do C on anything I have , think it may need tweaking on next upgrade ...

A beautifully minimal and accurate tuner with no ads or in app purchases. Thank you so much Jean-Pierre, much appreciated!

Seems to work very well for simple tuning tasks, but doesn’t like any C notes on my system. B - fine, C# - no problem, but C - needle shoots off the screen.

It does exactly what you need, no more no less. And a note to the writer of an earlier review she was having trouble getting the app to work. In my case, it worked fine on the pad forever, but I had to upgrade my iPhone to get it to work there, the retro download that was offered did not work. I would have titled this post “perfect” but that was used.

Just that.

It works!

Accurate, simple, free, add-less, and works exactly as expected! Helps me with my practice and doesn’t interrupt me! I couldn’t recommend an app more!

The frequency reading derived by this app is not accurate. Three other apps that I tested on my iMac and iPad derived the same tone frequency from my guitar and a test tone generator. This app is off by - 5.0 Hz. For example: a test tone of 80.9 Hz shows up as 82.4 Hz and a test tone of 181.6 Hz shows up as 185 Hz.

This App has issues. For one it doesn’t work. The App will open but freezes immediately and is not functional whatsoever.I’ve decided to uninstall this app .

A great tuner with a great developer! There was an issue with the tuner awhile back, but it’s all fixed now. Thanks, you rock!
