I love franglais
Please update the app 3/5
On the latest release of iOS for iPhone your app crashes when trying a 2-SampleTInt confidence interval function. Anytime I input my values the app crashes when I “scroll” down to the “Calculate” button. I tried this with lots of different data with the same results for T or Z 2 sample interval functions. I am a lifetime subscriber and paying customer and really rely on this app for school.
If you’re a student and study on your phone this is a must 5/5
Im always studying on the go and having a good calculator on me 24/7 has made it so much better
Love it 5/5

Lowkey been using this app since algebra 1 saved me through many late night homework assiments.
Ti 84 Calculator 5/5
Great calculator so so happy I found this app
Good simulator 5/5
Adapts to generic graphing calculator accurately and with adjustments to work more conveniently for touch screen. Pretty much all content present in the official old fashioned calculators is here, with good additions added on top. Works fairly well on my 64gb base iPhone 11 and 256gb iPad 9
This is so helpful! 5/5
This calculator is great to have on your phone. It never glitches. I use it all the time for my Algebra class!
Pretty good 4/5
Some times the answer is a bit off compared to a actual TI 84, and zoom stat doesn’t work. It doesn’t actually graph any points.
Love it but… 5/5
I love this app but does it work with iOS 16 because I updated my phone and now cant open it.
I love it 5/5
Thank you for making this wonderful app
So sweet 5/5
Ive been using this through my math classes for years to avoid spending $100+ on a calculator and its so amazing. recently they updated the app and wrote an honest message about how they were finally going broke, but they knew people couldnt always afford it and they wanted to keep things accessible, so they clarified they would be adding ads, and honestly thats all I ask of apps. Honesty and respect. I love that they just talked to their users like human beings and still care and arent making people pay for it. I will watch a million ads for you guys. thank you
Best calculator app by far 5/5
I love my TI-84 but I forget it all the time when I need to use it or it’s out of battery when I need it. However, I’m NEVER without my phone and this app is the best calculator app because it’s just a simulation of the same calculator that I love. It’s so intuitive if you own a TI-84 and are used to it and it functions just like it. OH AND IT’S FREE. So worth it saves me countless times in lectures or recitations when I need to whip out some quick maths.
The best calculator 5/5
I have this calculator for 4 years and ounce I heard they needed to start putting adds I gladly paid the $7 for no ads. This is the best app calculator and instead of paying $150 for the actual calculator it’s $7 and in your pocket all the time. This has saved me carrying the bulky calculator. I have yet to run in a problem and I use this app more than any other app on my phone. Overall perfect execution from the devs.

Works great, perfect to use for college algebra!!✅

Best calculator! 5/5
This has to be the best calculator and the best part is that it’s convenient and free to use!
Even simple addition was wrong. Dissatisfied. 1/5
Even simple addition was wrong. Dissatisfied.
Matrix issues 3/5
The matrix system doesn’t work properly - doesn’t save some of the numbers I log while typing, giving me some weird answers
a real graphing calculator!! 5/5
mostly works as a regular ti-84 would.

I LOVE IT AND USE IT EVERYDAY 5/5
By Bunker boy 🍤
Guys I literally use this app everyday for my homework. We are not able to take the school calculators home so this app comes in handy all the time. With out this app I would be no where.I would be lost and wouldn’t know where to go😿
I love it so much I can finally do homework yess🤩🤩🤩🤩🤩🥳🥳🤩🤩🤩🤩🤩🤩🤩🤩🥳🤩🥳🤩🥳🤩🥳🤩🥸🥸🤩🥳🥸🥳🥳🤩🥸
You all are doing a great job! 5/5
I’ve been using this app for years now, and i really appreciate all the work you’ve done. I’m happy to pay the money to become a member and remove ads, because you are doing important work for access to a usually very expensive calculator. I genuinely appreciate how easy it is to use, and it’s by far the best calculator app i’ve ever used. superior to any other free apps u could get, even with ads! Thank you to everyone at your team!
- a very grateful student
Plz don’t go away 5/5
I really like this because sometimes I need to do algebra homework and I don’t have this kind of calculator
So Awesome!! 5/5
I love this calculator so much, most of my teachers even let me use it in class, i always just borrow a real calculator when it comes to the test because yk, phones are cheating or whatever. But still 5/5 stars, love this app!!!!
THE MOST AMAZING CALC APP FOR IPHONE PERIOD 5/5
I mean it just works the way you want it to. It’s so good. One thing I would really love is to copy and paste previous answer. I’m having to store values and stuff but other than that it’s A++
Great when you forget 5/5
This does pretty much everything a regular TI-84 does. I use it as a teacher!
I use this app to work, not watch ads 1/5
I used to use this app all the time for general stuff, like school and some work at home, but now I can’t use it without getting an ad shoved down my throat every minute. Thanks for ruining this app, I’ll be uninstalling.
New idea 5/5
Add a delete button so I don’t have to keep typing out the same problem
Great Help 5/5
By Shrey's sexy revews
Useful in a pinch when I can’t find my calculator and It feels just like it. In fact I sometimes prefer using this over my Ti-84 CE.
saved me so many headaches 4/5
the apple calculator is useful but this one has EVERYTHING, its perfect
i wish you could delete single numbers instead of having to rewrite the whole expression, but it’s worth it
This app is perfect for my geometry class 5/5
Sketchy ads 2/5
By wild goose96
The app used to be really good before they added the random pop up ads that look like a cesspool of viruses. There’s also no warning and the ads are as deceptive as possible to try to trick you to click them. Wouldn’t recommend to younger kids.
Awesome! Saved me So much Money 5/5
By Tïttïe milkies
This app is awesome!! It’s just like a Ti-84 but I didn’t have to go out and buy one I can just use this for free! I just figured out how to do the echelon method on it so I’m very happy! :)
Simple random solutions doesn’t work 3/5
When I type my seed and then “sto” I click on “1:rand” and it doesn’t let me continue from there when I press enter.
The answers change when doing Pythagorea theorem (when input the same problem again)
This is a great companion to the TI-84 5/5
What a wonderful app. Easy to access and a great way to learn the functions of the TI-84 for homework and for training for the ACT or SAT.
By волынский партизан
In the last update, the author "forgot" to indicate that he introduced advertising.
Great app! 5/5
Super great app that has everything graphing calculators have. Thanks!
Missing a few things 1/5
Update: Think you gave many (me, at least) the impression that I would never see ads if I got the app before you monetized it. Anyhoo, no more bug reports, also will be deleting.
+1 on mathprof2’s 25APR comments. Also, it fails to graphically determine a maximum for the Box With Lid example from the TI-84 manual. Please fix those items & I’ll also change this to 5-stars. Still, overall, well done. Update: Appears you’ve fixed the graphical max bug, nice.
HUGE HELP 5/5
completely worth the price this is amazing for graphing functions
literally a ti-84 5/5
if you need a ti84 for school, work or anything else, you don’t need to spend $100 for a calculator. (if you have a lenient cell phone policy) I have yet to find something that the ti84 does that this app can’t. I highly recommend for high school/college students.
It's really good for school
Ads...why, oh why... 1/5
Hey, thanks for finally adding ads. It really adds to the experience. Not. Would've preferred you halt development if you're broke instead of forcing me to see ads if I want to continue using the app. Honestly ruins the entire experience for me. And no, I'm not willing to all of a sudden pay money for something I already had legitimate free access to, which was an ad free experience in the app. Truly a shame.
Calculator App Review 5/5
By loretta sunshine
Super easy to use - way cheaper than purchasing an actual graphing calculator. This app saved me for an accounting course!
