Cleartune is a chromatic instrument tuner and pitch pipe that allows you to quickly and accurately tune your instrument using the built-in mic in your device.

Cleartune features a unique "note wheel" interface allowing you to quickly find your pitch, paired with a highly responsive fine-tuning meter for the perfect tune.

With support for custom temperaments, transposition, notations such as solfège, and adjustable calibration, Cleartune packs more power than most pro tuners, yet is simple enough for everyone to use.

Cleartune can tune acoustic or electric guitar, bass, bowed strings, woodwinds, brass, piano, tympani and any other instrument that can sustain a tone.

Most electronic tuners cannot properly tune a violin. With a built in temperament for violin family instruments, Cleartune will have the 5ths singing perfectly.

Suddenly I can’t set it at low pitch

Suddenly I can no longer set this tuner to A-415. The historical temperaments still work but I need to be able to change the A to a lower pitch. I can change it but it immediately changes back to 440. If you fix it I will restore my five star rating. Right now it is useless to me.

“Laggy”, phrases, hard to use

The features are great, I love having the different kinds of intonation, but the app only works in fits and starts. As you tune, it doesn’t follow the pitch, then all of a sudden it catches up and overshoots it. It is very, very difficult to use this to actually tune an instrument, and I looked for …

Really well designed app. It really needs an update for bug fixes and for general smoothening of the UI.

App used to be amazing.. what happened?

This was once my favorite tuning app. Now it freezes on the regular and lags when I try to change tones with the tuning dial. How frustrating! What happened Cleartune developers? I'm using an iPhone Pro Max and this app acts like it's struggling. I wish the developers would fix the app to wo…

Great tuner needs some love from the dev

The was my first iPhone tuner and is still my favorite. No frills, just what you need. At some point however the mic level or something seems to have changed. I can’t tune my electric violin without needing to plug it in. Works great for ukulele. Also lately when manually selecting pitch using the p…
