Accessibility Comments

There are many unlabeled buttons, and the thing seems to respond unpredictably.

VoiceOver Performance

VoiceOver reads most page elements.

Button Labeling

Few buttons are clearly labeled.


Some parts of the app are accessible with VoiceOver, but not enough to make it usable.

Other Comments

I never got it to work for me; I can't tell if it's VO giving me sass or if it's a poorly programmed app.
