Calculator works well 5/5
It runs as expected
Missing “quick” tabs/keys 1/5
The “x” and the “abs” do not show up in keys at the top in f(x) format (in the $5 pro version)
This calculator app is awesome!! Takes hours and total frustration out of my homework, wish we were allowed to use calculators when I was in high school! Well worth the 5 to download the pro one! Amazing tool.

I got the App. When I tried to use Solver, it indicated I needed the upgraded professional edition. I bought it. However, after bought it and getting the OPEN button, it won’t open. I have looked at it and after more than 20 minutes, it is still saying waiting as it is “loading”.
It’s difficult to figure out 1/5

I can’t find the blasted Zoom key, please help! Thank you.
Errors with financial NPV solver
Good ... but 3/5
By No nickname (lol)
When I try normalcdf it would give me an error.
There also no manual for it so it took me some time to understand on how to work it.
By Ayed Almudhafer
hi this calculator is very good
Decent for what I need 4/5
I’m a student in school and have been looking for a graphing calculator similar to the ones in school. I stumble upon this and pay and it works just fine. The menus like when you do 2nd y= is very hard to track but everything else is ok. I would recommend this. However I would like an *EASY* way to back out of the y= area as of right now I don’t think there is so I have to close and reopen the application.
Share function doesn’t work. Critical! 1/5
I purchased this version to support my online teaching efforts as our school has adopted a distance learning model with the COVID19 virus pandemic. Unfortunately, EVERY time is tap on “Share” in the graph display, the app crashes. I’m on an iPad Pro with the latest version of iOS. I hope this bug can be sorted quickly.
TI 84 Emulator pretty good 4/5
I have been having a little bit of trouble graphing quadratics, but otherwise this is a great calculator
You can only use the table once
Love but Graphing window could use some work 3/5
I love this app it works exactly like the ti 84 but with a touchscreen but the only problem is that I can’t change the scale in the window tab while creating a histogram. That’s a huge downer for me.
too confusing 1/5
i really don’t like this calculator, waste of miney
Helps me with my geo homework when I need a calculator
BEST APP EVER 5/5
For the price it’s well worth it because some calculators can cost up to $200 so well worth the 5 dollars in my book
Great product! 5/5
By El Grande Mo
Delightful to use on the 15 inch iPad.
Idk if I downloaded the same thing as everyone else LOL BUT THIS DOES NOT REPLACE A GRAPHING CALCULATOR ANOTHER 5$ lost to false advertising
Very difficult to use and cannot handle basic algebraic applications 1/5
I spent hours trying to figure out how to perform the most basic algebraic functions. I am unable to determine how to even input variables. The catalog was no help. Not recommended. Also note that Apple will not refund your money on this app even though it does not work properly.
Updated Icon? Great App! Amazing functionality! Download! 5/5
By wat did diddy do?
This is an amazing app with amazing functionality and help. UI Looks great on IOS 13, but can we get an updated icon? I’d love to display it loud and proud on my default home screen and the current icon looks like a 1st gen iPhone app icon.
Horrible App 1/5
Entering anything ... the basic delete key does not work. Hate this app. Tried for a refund. Apple refused to refund. What a total ripoff!!!!! Really.
Apple should be ashamed.
Contacted seller. Told me to use the broken, useless Apple system to get a refund.
Total ripoff and cluttered, useless app.
Good with errors 4/5
Product is fairly good, but does appear to have bugs. For example the rowreduce command on a 4x3 matrix crashes with a wrong dim error. But this was also a problem with the old ti-83 calculator
Waste of money! The apps button doesn’t work the way it’s suppose too to add in information.
School help 5/5
It helps a lot for school as at home I do not have a graphing calculator
It’s wonderful 4/5
This calculator app was absolutely stunning. The only reason it does not get five stars is because I had to pay five bucks.
By The King's Nomms
It has all the features of a ti83 and much more and it’s totally free. What more could you ask for?
Can’t simplify some algebraic expressions 3/5
Comes up with a syntax error when trying to solve/simplifying algebraic expressions. I can enter it exactly as it is on paper and it can’t solve it. For $5 I expected better.
By JackAndStuff #Youtuber
Don’t like it 1/5
I downloaded this app to use it for my math class. I tried to use normal cdf and an error sign popped up, I tried to use different way to do it but the error still popped up. I’m very mad about this because I had homework due today and I can’t do it with out that.
Joe math 5/5
By trash todjjx
I downloaded this for my son to use for his math homework because his fancy calculator was at school. It kept saying “error” and couldn’t calculate what he needed!!
Great for college! 5/5
Needed a ti 84 for college, and found this app! Much cheaper to buy this $5 app than the $100 calculator. Works great with iPadOS multitasking, and fully emulates theta 84
This saved me $130 for a t1-83/84 calculator for one statistics class. Takes a little bit to find some of the function such as combinations and permutations but couldn’t get through this class without it.
TI 84+ app 4/5
By frank samona
I am a math teacher and think that the app is very nice. Couple of thinks I am having problem with, I am having hard time in the mode to change to two decimals only, second is, under the TVM solver I cannot change the PMT from END to BEGIN. Any ideas?
Best ti-84 for iPhone
ITS SO AMAZING
This app doesn’t graph. Cost 5 dollars and it doesn’t graph anything. The enter button doesn’t work and you can’t put in an unknown variable
This app is so easy to use and i love it
So much to love for a good price. 5/5! It is a must buy. 5/5
By Darth Lightning
A couple of days ago I was struggling to complete homework for Math and when I had to work around it, my dad offered to buy this for me. I thanked him a ton and to this day, and hopefully for the rest of my life, I will cherish having this and be thankful this exists. It has all of the functions a graphing calculator has including converting a decimal of any kind to a fraction if possible, and a ton more things. I would recommend it to anybody who desperately needs a calculator for homework or work and it’s only 5 dollars and you will not regret buying this app.
By what the fuuuuck
Pretty close to the ti 84 4/5
I would like to see the solver function added and then it would be awesome
Good calculator app but not giving correct results 5/5
I tried to do y=x^2 and y=2x+3 graph it shows x^2 and y=x graph always doesn’t mater what I change. It might be a bug, I tried this with real ti-84ce it plots good. Don’t know how to trust other values if it fails for simple plot.
Premium was worth it but.... 3/5
Overall this is close as it can get to an actual graphing calculator but, Is there a way to get more apps in the calculator? Currently there is a few in there but the UI looks like it can fit more apps in there and to make the calculator more useful, more apps should be added for the user's choosing. Love the app saved me every time I can't find my real graphing calculator 😂😂😂 keep up the good work!!!
Dysfunctional Calculator 1/5
When I enter an equation it fails to graph, when I change the min and max values the graph disappears, I tried to change the scale and could not get it to change.
Buttons don’t respond sometimes
It’s like having the real thing ! 5/5
It saved me in a crunch.
I broke my calculator by accident on test day. This helped.
Not Satisfied 1/5
I am not satisfied with my purchase and I would like a refund as soon as possible
Not a fan 2/5
This is just too confusing, and not like the TI graphing calculator that I used. Currently I’m using the calculator for calculus, and the graphing is very frustrating. There also doesn’t seem to be a good manual available to understand the calculator better. I feel like I wasted my money. This is also not optimized for an iPad.
By The Loat
Good need this instead of buying it
