Reviews: What People Think About Ncalc - Graphing Calculator 84
Buddy the Frog
Rating: 5/5
Out of what I know it lets me do almost everything on a normal expensive graphing calculator, but for free. Some things are locked unless I think until u buy the premium. But barely anything is locked. There are all of the buttons on a normal graphing calculator. You can click the same buttons to get the same outcome like a normal calculator. This makes it very less complicated than other calculator apps. Although, during some tests I am not allowed to use a phone which makes sense. I can only use a real calculator. That’s the one thing that I cannot use it for.

Overall this calculator works pretty well. However are no instructions on how to use it, so if you're familiar with a TI84 for instance, you can figure it out but its not identicial in operation. There is a 'help' section but if you click it, it says there is nothing there. Also the app continues to do a pop up asking for a 5 star review, so I'm leaving a 2 star as a result. I paid money for this app, I'm not going to be bugged about reviews after paying money. One minor issue is the alpha button's color does not match the alpha button key options above the keys. This is usually matching. My overall review is yes this app works, it'll get the job done, but if you want a computer version of the TI84, look elsewhere as some of the commands within this are complicated and there is no guidance.
Calculator unable to handle equation 14!/(3!11!). Gives the error message "error: syntax error" . Whereas my portable regular TI84 calculator can handle the problem without issue.

I have been generally impressed with the capability of this calculator, and it is my "go to" calculator for vector operations.
However, it has some serious and unexpected bugs. Some polar-rectangular conversions have unexplainable errors using particular angle values, and some list functions provide grossly wrong answers (wrong sign, wrong magnitude).
Update: The author responded with a work-around for the polar conversion issue. The multiplication of lists still gives unexpected results
