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 bought the premium service because I was very satisfied with the app initially. However, there is one glaring problem. Only some numbers can be seen with the full range of Result formats after you tap on the answer and click on “More”. For example I would like to see a number in Engineer or scientific notation, but one answer will not have these formats shown (after clicking on more) whereas others will. It’s a very irritating problem as the wide variety of results is really useful when available, but is really frustrating when it isn‘t.

Great calculator, has all the functions of a ti84 plus a few more. If it had touch bar integration and better copy and paste that would make it even better.
