### 5/5 — Wonderful

*2025-03-15, version 3.0*

I only write reviews when I am impressed with the app. I am extremely impressed with this calculator "plus". Excellent work. One quirk is having to add keys to the keyboard, however, I can deal with that. Thanks!

### 4/5 — Great for Review

*2020-06-26, version 3.0*

This app has been excellent at helping me remember calculus concepts that I might forget. Obviously, there are a few flaws, but it’s pretty good overall.

### 4/5 — Summation missing.

*2020-05-09, version 3.0*

I have had this app for a couple of years now and Appreciated it greatly until I tried to do a summation. This seems to be a serious flaw considering the manner in which calculus is taught. What is one to do, use an integral instead?

### 1/5 — Don’t download this shi

*2020-03-24, version 3.0*

It’ll ask u for your Apple ID. Don’t put your password in. And u gotta pay for the content that is really important.

### 1/5 — I feel scammed

*2019-11-13, version 3.0*

So the app worked fine,

Until I paid the premium version which cause my app to never open again. There goes my 10$.
