Zen Tuner

Open source, simple, no ads. Perfect.

I like this app. The almost analog behaviour is refreshing after using tuners that display digital results with numbers. This has one simple line which moves fluidly like an analog amp meter or something. It doesn’t jump around or have flashing unreadable numbers like other tuners I’ve used.

I didn't notice and it's not clear from the product description that this app only supports tuning acoustic instruments. This is because it only uses the microphone, and doesn't allow selection of any other audio interface. So while it looks beautiful and may very well work well, I wanted an electric guitar / bass guitar tuner.

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!
