"My most indispensable app is my guitar tuner, Cleartune. None of the old visual or analog tuners are as precise. I've even taken it on stage with me!" - Rosanne Cash
"Cleartune and Clockwork are my most used apps." - Ezra Oklan (Nicole Atkins, Norah Jones, Antibalas Afrobeat Orchestra, Matt Beck (Matchbox 20), Chico Hamilton, Arnie Lawrence)

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.

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 the website but apparently it’s gone. Apparently the developers are just still trying to profit off of a dead app that doesn’t work and isn’t supported anymore.

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 work like it used to back in the day. I guess in the meantime I'll just delete it and find a replacement.
