Good in a few places: But very expensive

Seems free. Makes you go through about four pages then make you’d pay for proper use of the app.
Quiz not helpful
I had already took calc1 and wanted to quiz myself as a refresher. My answers were correct but the app says failing under 80%. This is not helpful in that section.
Wrong
After going through the very first quiz and “failing” multiple times, I decided to go through it with a calculus calculator. All answers correct, yet I still wasn’t meeting the 80% minimum requirement. Hints popped up as completely blank white screens, and therefore stripped the app of all utility as I was unable to progress.

Other reviewer didn’t realize something…
There are two tabs at the bottom of the app. One is for quizzing, the other is for instruction. I suspect the other reviewer didn’t realize they were in the quiz portion. The app actually is very thoughtfully designed to teach calculus. You can see in the free sample version that this is the case. Give it a try, it’s great!
