Some issues

Good concept. However, the tone stops playing after you listen to it for a little while as the marker keeps moving. Have seen this on multiple devices and others have experienced this as well. Also unable to find proper of saints for the Novus

The Transcription Sound does not Work

Great app! But the title says it all. Unfortunately, I am not hearing any noise when I play any chant on my iPhone SE.

Very useful!

This app is most useful for Gregorian Chant, especially if you deal with gregorio files any. You can produce the chants for the day and you can export the .gabc files for use in Latex if need be.
