Pinyin Chart - Learn Chinese

After upgrade to latest release, the Audi no longer works on iPad nor iPhone… disappointing. Been using this app for years!

can’t get it to make the sound. checked iphone volume settings, mute and unmute, uninstalled and reinstalled. bluetooth settings. nothing worked for app to make sound.

I imagine this could be a useful app, it's not very pretty though. Although it is very functional. I must admit that I do not completely understand the concept of the application. I am currently learning mandarin although I am very early on but I' not sure how I am supposed to use it, like I said I imagine this could be a very god resource. Finally I do think the app could look better, it's a little off-putting as it is, not very modern.
