Just make it paid from the start if the free version is 5 questions per week. To put that in perspective, a single lesson consists of 5 questions so you won’t be making much progress. To respond to the developer response: I’m not referring to subscriptions when I say make it paid. Make a paid app. Am I really the only person sick of everyone asking for a monthly fee?
takes your textbook and gives you problems from exactly what you are learning in class. makes review so easy
I am currently a college student who is about to take calculus 2, and I have nothing but praise for this app. When I make a mistake I get direct and specific feedback, I have seen no bugs so far, and it has an incredibly comprehensive coverage of calculus topics. Thank you so much, keep up the good work!
