Please fix note recognition.
You always respond to iTunes app store reviews with a variation on "please contact us"
First, your response to me had an invalid email address (contact.yousician.com). So I changed it to firstname.lastname@example.org, and it's not valid either. So great job with the response.
Second, EVERYBODY complains about the poor chord/note recognition. Stop asking for device info. It's NOT other people's devices. It's the APP.

To the OP, FWIW I go directly into both my iPad and desktop app via an audio interface and don't normally have any issues with note recognition. Prior to using an audio interface that was however an issue for me too, so perhaps that's a solution for other users too.
I thought I'd respond to the comment, because in my opinion nobody at Yousician ever will! I don't even know if this forum is even monitored; I just flagged some obvious spam that had been up for weeks! I agree, I also provided feedback via the ITunes app store, and within a few days was told to "contact us" for help, despite not really needing any help, it just wasn't an especially positive review.
