best Ti 84 soft version calculator
Great app and it doesn’t make it so you need to buy anything.
Overall great. I started my new math term and couldn’t afford a real ti-84 so I downloaded this app and it’s great, so far I haven’t payed for anything and it’s just as good as the real thing. 5/5👍

Very much enjoy this calculator. I find this app. well done. I paid the developer. Bug fix request. When I enter negative 8(subtract 2) it should return an error. It does return 16.
Wow
I have a TI 89 and this virtual calculator is close to it. It’s nice to have on the iPhone. Plus all the material that comes with it. Very nicely done.
