FREEZING After latest update

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

Never works

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

Never has worked

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.

Too bad

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