## What is Cleartune?

"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.

### 1/5 — FREEZING After latest update

*2026-07-24, version 2.3*

Worked great for months unusable now even after reinstall and double checking microphone permissions WTF?

### 1/5 — Stopped working

*2026-07-16, version 2.3*

Unreliable

### 1/5 — Never works

*2026-06-10, version 2.3*

This tuner app never works. It’s like the mic is not connected most of the time, cannot pick up any sounds. I can run other tuner apps at the same time and they work fine so it’s not an issue with my iPhone

### 1/5 — Never has worked

*2026-05-23, version 2.3*

I have never had Cleartune work consistently since the release of the iPhone 12 and later. Waste of time and you may as well buy a real life guitar tuner rather than these digital/app based, poorly coded bits of trash.

### 1/5 — Too bad

*2026-05-11, version 2.3*

Spent $4 for this.  Worked the first day on iphone11, now is frozen.  It’s just a screen shot.

### 5/5 — Bağlama

This used to be a great tuner but no longer works on any of my IOS devices.

### 3/5 — Freezes a lot

*2026-01-29, version 2.3*

Works as a last resource. Not so reliable.

### 1/5 — No longer works

*2026-01-20, version 2.3*

This app no longer works. It’s almost 15 years old and hasn’t been updated in 5. Avoid.

### 1/5 — Terrible app

*2026-01-15, version 2.3*

Absolutely terrible doesn’t even react when i play a string
