This app is absolutely brilliant. I can manipulate the music in so many ways, e.g. slow down the tempo, chose individual parts to sing against, get real time feedback for mastery of my part. My chorus often sings in 6 or 8 parts and being able to isolate my part in practice at home is invaluable. I loved the portability, I could practice anywhere - on my lunch break, outside on a nice day. Several members of my chorus also used it this summer when we had virtual rehearsals and now they are hooked as well. The support team was excellent when I had difficulties uploading some of the scores. So happy I found this!

I wanted to like this app but have been unable to get very far on it on my phone. The first few times I would get to the chosen song and it would crash or play a few notes and crash. After a number of tries I got to hear the entire song and move to step 2. At that point it just froze and eventually returned to the get started screen and cycles through step 1. I may keep trying to see if I can see how it actually works. I did get the metronome to work but very slow to change speed.

The Pixel-bug has now been fixed - Yay! Now, I am able to enjoy singing on this app! For purely acoustic singing (without Record turned on) , it is very helpful and enjoyable. But, the software seems to have trouble tracking my voice as I use the record function and starts to stick and sometimes freezes altogether. Also, it seems to pick up the second harmonic when I sing in head voice (not falsetto). It plots my notes in the soprano range but I'm definitely singing in the tenor range.

Hi! We just updated our response to your support ticket about this issue. We've rolled out a fix for the Pixel calibration bug and you should no longer have this issue after you update to the latest version of our app. It would be great to hear if this worked for you. Let us know!
