Ratings and reviews

Works great and is easy to use, only 'bug' so far, clearing variables causes the app to ask to clear all matrices too which can cause problems if you double-click. Also the animated button on the lower left is distracting and the unit converter found there can be accessed via the CONV button so no need to duplicate it. The most complete and easy to use app of it's kind. Only minor tweaking would make it better.

So I accidentally broke 2 of the actually Ti-84s, but this app is almost identical and a little more user-friendly sometimes. I don't have the premium version and some things like derivatives, integrals, and limits require premium, but I'd just use SymbolLab online for that. Most phone calculators suck (particularly iphones), but I prefer to use this app over the actual Texas Instruments for the vast majority of the time, and I've been using it for a year now. 1 con: No instant fraction setup

I could afford a real TI-84 for my grade but I stumbled on this app. I was really happy that I had found it, but I was disappointed because it didn't have the ZTrig zoom option and the Yscl parameter for graphing. These two functions are exactly what I needed for my grade but they aren't there.
