Top level calculator

This calculator is able to calculate nearly every equation I have encountered. I am happy that this new version still maintains the core calculating program on the device rather than solely relying on cloud computing - incase there isn't good wifi or cellular reception.
The other things I especially like are that this app enters and displays the equation in textbook form. Also the layout maintains the likeness and function of a standard scientific calculator which doesn't rely on typed in strings like many other CAS programs.
Couple things I would like to see are a more complete and updated manual and also making full use of the key size to make every number/function/shifted function more visible in poor lighting when in a hurry.
Overall this is probably the best easily usable CAS app available.

Demands a review

There are some interesting things that this app can do but overall it is weak. The documentation is poor and does not match the keyboard in places. The commands require a lot of keystrokes because the keys are not on the same page. That also confuses the syntax. There are only three functions and they can't be named or saved, so it is an exaggeration to call it programmable. The derivative function is pretty worthless since it only handles trivial expressions. Many other issues. I had fun playing with it but a "go to" calculator it is not.

Loving it!

Much, MUCH better than the standard calculator in the phone. It's a good idea to watch the tutorials, in my opinion. Otherwise, you might be sitting for minutes wondering why a function will be taken off the graph but still be on the side as you return to normal screen lol Awesome graphing calculator!
