Non-native speaker but probably tried 20 times? I had to force it to make it work.

I'm very very sure I can do the first tone.

Would love it if this thing did work reliably though. Also would be nice to have one Cantonese.

Hi, yes the classifier needs some improving. We expect that it would be much more difficult to make an accurate classifier for Cantonese, although we could make a website which presents Cantonese words/phrases and lets you see your (and the teacher's) pitch contour. Would that be of interest?
