Buddy the Frog,
This is great 🤩
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.
Toadsroberts,
Annoying pop ups requesting reviews, no help/instructions and operations changes between ti84
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.

Moon FLWR,
BEST online calculator!
I downloaded multiple calculators! I had a TI86 and didn’t have the right functions for my Statistics class. As the class continued the other calculators were still missing equations and functions. This one has all of them! I am so thankful I didn’t need to buy a $100 calculator for one silly class. I only paid $2.99 or $3.99! Totally worth it.
VaprRIZE,
Would rate 5, if not for one glaring problem
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.
campbell-j,
Great app
This is super helpful for someone like me that doesn’t own a calculator right now. It is literally a calculator just in ur phone. Super easy to use, there is a premium version but it isn’t necessary and it is amazing definitely download it right now
Garcij2,
Useful
If you want to practicaly have a ti-84 amount of functionality for 5 dollars this is it. This may sounds likea fake review but i cant get over the fact that this app does what a 200 dollar calculator i was "required" to buy can do. Thank you for this youre the best.
the uptimate nickname,
I mean, a graphing calculator that’s free…
For a free calculator app, it’s a whole lot better than the basic phone app. So far it hasn’t shoved ads down my throat, so that’s also pretty good. Overall $80 cheaper than getting a ti-84 plus u have a graphing calculator on your phone.
sthoppay,
Excellent with all and more functions than the Ti84
Have been using for two weeks. Quite impressed by the similarity between the actual Ti84 and this simulated app.
toobafan,
Beware serious bugs
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

TI84User,
Use a ti84 without taking your hands off the keyboard
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.
