Terrible

I like the UI but most of the time this app won’t work, even in very quiet environments it won’t pick a note at all. Waste of money.

Used to be amazing

This used to be the single best tuner in the App Store. Alas, no longer. Now the latency and delays are so high that it's mostly unusable on modern iOS. The lack of any update in 6 years is causing it to show its age. Farewell, Cleartune! We made beautiful music together!

Lovely no frills app

I just use it to tune a guitar, and sometimes ukulele. It does what I want it to do, no distractions, no in-app purchases. Perfect!

Freezes

It freezes continuously despite deleting it.
