Never fixes bugs
Okay, quick review videos but the bottom menu is in the way of selecting the videos at the bottom of the list. Another review listed this issue over two years ago and it has not been addressed.
Tremendously helpful!
This app certainly strengthens calculus concepts very quickly, as well as provides refreshment regarding precalculus preparatory concepts. If attendance to class wasn't mandatory, I'd feel comfortable using this app as a textbook companion to successfully complete my course.
It wants your email address - NO!
I'm not giving my personal info to an app that could do who knows what with it. If you don't want to give this information, you can't even get started. A big thumbs down.
Excellent App and Great Teacher
That app helped me a lot in learning calculus deeper , I hope you add more lessons for more advanced courses !
