1. Then I asked for a refund (as I had the pro version) and no one even cared to reply or to send a refund.epic app!!! I recommend this app to all those who have difficulty in solving calculus problems.It makes us understand the problem and has step by step method of solving the problem I love this app😍The app got closed of nothing, I was trying to write the exercise then it closed, definitely i got annoyance because i bought the premium version.You can only use it to solve a few problems, then it tries to make you upgrade to the premium version to keep using it.This app is one of the greatest Mathematical app I encountered.

2. I bought the upgraded version to do a larger variety of derivatives - disappointed.How do I find the key for the mathematical constant 'e'? I looked for it in the menu "+keys" but it's nowhere to be found! I tried the alphabetical 'e' key but it doesn't seem to work! Please respond.Why if we are going to put the questions are said (incomplete) even the question are complete? By the way i'm thankful for more examples and explations, I've learned a lot❤ Hopefully you will going improve your application, so that the people are impress to this apps.Many of the buttons don't even work and make the app to crash.

3. The free version may already be better than spending money on a premium.It cannot solve the derivative of x to the power x.

4. I love this app and all versions, but I hate it when I have to spend money just to complete subscriptions, either annually or monthly.

5. All other programs can do it without going on-line.

6. I asked for support and got no reply.

7. Very helpful in my understanding of Integral Calculus.
