Khan Academy: Trigonometry App Reviews

The app has been really helpful as my precalc textbook that I had to buy for class is terrible (thanks, Pearson). However, its really really annoying how the presenter clearly is talking based off bullet points or on the fly because he regularly interrupts himself and makes mistakes. When youre recording a video that can be redone easily it makes little sense not to edit out the errors. Again, very grateful for the free app but just some advice going forward.

No audio with this app on iPhone 6, ISO8. It’s useless without audio.

I was so excited to finally get help! Then... Im watching... Watching... Watching... No audio :(. So disappointed. My software on my iPhone 6 is up to date, too.

Keep it up brothers
