Wonderful
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!
Thank you

Best investment of my college career

Nice
Great for Review
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.
Summation missing.
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?
Don’t download this shi
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.
I feel scammed
So the app worked fine,
Until I paid the premium version which cause my app to never open again. There goes my 10$.

Astounding ! this is The Best of All Time !!
a Bohemian Rhapsody of Mathematics !!
This app is a scam
Paid $6 for full access as soon as I paid app stopped working. Scam. Save your money.
Excellent
The recent update is much appreciated. This is one of the finest math-review tools I use. In an instant math concepts can be researched and I find my forgotten knowledge refreshed, well done.
Animated Solutions Board is not functioning
Though this application has topics and concepts that are seemingly helpful, there are parts that don’t function as expected. I purchased the premium package sometime ago with an older iPhone... it worked.
I have had my iPhone X since they were first released, and the above referenced feature crashes when I attempt to launch it. I sent an email several days ago, but have not heard back from the support team. Hopefully, the app is still supported and is not one of those the developer allows to die on the vine!!
On a scale of 1-5 with 5 being highest:
Reliability - 1
Quality performance - 1
Customer Service - (-1) off the range
Information - 1
Value/Price - 1
Overall, one star until, and if it’s corrected!!

Poor
It’s good
But requested for payment after solving 3 questions

Glitchy and lacking
The first calculation I performed with this app crashed and didn’t even have the factorial (!) key. Still looking for a good one....
Definite thumbs up.
As a high school math teacher- who left the classroom to raise our daughter- I find this app to be very useful. I remain certified and tutor many students. The problems give me practice and refresh me on concepts that I’ve forgotten. Definite thumbs up.
Don’t go Premium
Every time I try to calculate a problem, it shows an error. It’s useful as a resource but that’s all.
Needs organization
Great for simplex problems, but needs a lot of organization. A lot of problems I have I can't input because the sustem doesn't allow it.
Amazing
Saved my life
