FX Calculus Problem Solver

Great…

Nice it was amazing

Assuredly, Thanks!

Best investment of my college career

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.

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?

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.

Paid $6 for full access as soon as I paid app stopped working. Scam. Save your money.

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.

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!!
