User reviews

Doesn’t seem to recognize any sound input?

I’d love to actually evaluate this app, but it seems to fail on the most fundamental level of recognizing input sound, which leaves it pretty useless as a tuner. Would love some developer feedback and I’d happily update my review.

Response from developer

Thank you for letting us know, and we're sorry for the trouble. We've identified an issue affecting sound input and are preparing an app update with a fix. Once the update is available on the App Store, please update the app and try again. Thank you for your patience!
