Latest update hard to see. Too small.
At the risk of sounding like an old man (39) the staff is now too small. Mostly the accidental within the staff are tough to make out clearly. This was never an issue before. I think you sacrificed function for style.
Also, since the latest update, the sound during ear training comes out the speaker of my phone even while plugged in to my headphones. No other app on my phone has this issue. No more private ear training on my daily commute to work.
Still a great app but may have slipped a bit backwards.
