GraphNCalc83 Hodnocení aplikace

Very helpful

So close to the TI calculator, I only need my device most of the time.


My teacher recommended me get this app but when I heard it was 5.99 I was like wow it’s overpriced but yeah it’s overpriced but it’s pretty good

Don’t spend your money on this

I got this app purely so I could do math homework since my calculator wasn’t working, so I download the app and nothing works. The UI is absolutely horrendous, and the whole thing doesn’t work. I tried for hours to get this app to work, but it just doesn’t. It’s just horrible. Do not, under any circumstances, but this app.

Wow! Faster than my TI-84 Plus CE

This app does everything my TI-84 does a hundred times faster with more colors and way better resolution. Graphs draw with LABELED axis markers and you can instantly find intersections just by dragging your finger over the intersection point. It worked perfectly for my stats class last quarter and this new update is even better! I LOVE the new font size arrow keys and the math typesetting and the shading on the display makes it super easy to find your result. Thanks developer for another great free update👏👏👏


I have had this app since 2014. I bought it because the stats class I was in needed a specific function on a graphing calculator but I didn’t want to buy a brand new calculator. This has been my go-to calculator since. The only issue I have and it’s more pet peeve than anything, is that when you calculate a number and it won’t be a whole number the answer comes out as a fraction and then you have to punch in a few numbers to get a decimal. It’s annoying but other than that the calculator works just like a normal one for less money.

Well Worth the Money!

I am a high school mathematic teacher. I have tried many app calculators and this is the best second only to the TI nSpire CAS app. This one however is very intuitive and if you are used to the TI 83 or 84, this calculator will seem very familiar and has more features than the handheld calculators. I highly recommend it!

Great Calculator

Works just like my TI-84!!! Love it!!!

Amazing app

I have been using this app for chemistry, physics, and calculus. It’s a game changer when it comes to graphing since it’s touch screen.

Fantastic App!

Thank you so much for this, I can imagine how useful this will be for me in the future for my college years! The reason why I bought this is so I am able to help my friends out much more effectively when I am not at home (meaning I don’t have access to a calculator to check). I absolutely love this also because of the button layout and everything is exactly like my TI-84 Plus CE so I am able to use this to its full potential. Please keep this fantastic app running, you (the developer Ernest Brock) are amazing to say the least.


I love it. It has all the functions of an $80 calculator for 1/10 of the cost. Would definitely recommend!


It’s even better than real thing. Furthermore they keep adding useful features.

Great app for HS math class

I use this app when teaching my HS math classes. Students are able to follow along on their calculators. Great app!

Great functionality with regular updates

Couldn't ask for more from a small developer


This app is awesome. I cannot believe the range of function that is offered at the price point. As a science teacher, I appreciate having this app available on my phone alleviating the need to constantly have my TI-84 at hand.

Great App for teaching math classes

I teach several math classes in college and this is excellent for demonstrating TI-83 and 84 in class. So very close.

Love the new version

Everything I already loved plus beautifully formatted for the iPhone X screen. This has been a solid product for years.


As an educator, I use the TI in the classroom. I waited a long time for an emulator to come to iOS, and this one does an outstanding job.


I use this app daily for all of my engineering responsibilities! Excellent app and well worth the modest cost. Updates! The developer regularly updates the app. Thanks for making this awesome app!

Great App

I am a math professor and I use this app daily. It does many math computation and the program mode is fun to work with. An indispensable tool for me to have in my teaching😀

Great app - use it everyday!

The app developer provides free updates and the app itself works perfectly.

Best App I Have

I don’t normally write reviews but the developer here deserves it. This calculator is simply amazing! It uses the power of the iPhone with the simplistic design of the TI series. I’m not lying when I say I use this app daily. Well worth whatever I paid for it 4 years ago

He did it!

I don’t know how Mr. Brock does it but this calculator is great! It must be a labor of love because it has truly paid off. A faithful and very functional replica! Thanks so much!! Update 8/15/2018: Amazing app that continues to be improved.

Works perfectly

Great app.

Exceeds My Expectations

Works just like my TI-83. Haven’t found any issues, and utilize it for my electrical engineering needs.

How do I change the color back


Powerful and user friendly

This calculator is a must have. This one has everything.

Great for students

You obviously can’t use this app in place of a calculator on exams, but for homework and studying it’s a great tool!

Really good

Okay, it has arrived. A very decent TI-83 clone for the iOS. Looks to be very close to key-for-key to the actual hand held device. Many thoughtful enhancements to the UI, particularly in graphing. Everything I expect to be there in Stats looks to be there. I was particularly happy to see this app play nicely with other apps, like my drawing app, for multitasking. I can show, draw, calculate, all at once and that is so nice. Whoever wrote this app: A+.

My favorite paid app

This app saved me this semester. I haven’t been able to find my graphing calculator and I can’t afford to rent one, but thankfully my professor doesn’t mind me using my phone for this calculator during class.

Great App

I love this app and recommend it to all my students.

Thanks from a blind student

Hello, I’ve been using this app for 4(?) or possibly even 5 years now. It’s the best app I’ve ever downloaded. I don’t think I would have been able to get through Calc BC without it because I couldn’t see a regular Ti-83 well enough. If I could give it more stars, I would. Most of the time, it’s far better than Desmos. Being legally blind, and having the capabilities to do complex math is a life changer. Only thing that sorta bugs me is the splash screen and app icon because if a teacher is peaking over my shoulder they may believe me to be goofing off (happened a few times) because my original iPad Air takes forever to load it (I’ve been looking at an iPad Pro for the bigger screen but they are way too expensive. Well anyway, thanks to the developer for literally changing my life. I appreciate it.

Graphing calculator

This is actually the calculator that schools use. The ti-84 . I love this even though it’s 5 bucks. Worth every penny.


My TI-83 is temporarily down in action from battery acid, but after starting to use this app I haven’t even bothered cleaning it yet. Truly impressive quality control and replication of all the functions. Thank you to the developer!


this doesn’t seem to be the calculator i wanted please refund

Awesome - better than a real TI-84

Love this App - don’t need to haul another device with me. Now has fraction mode just like a TI84

Great customer service. Awesome application.

This app's developer is the best. I had a question after I purchased and he was on it in less than 2 hrs. He even comes out with improvements on occasion for free. It's awesome. This calculator is better than my ti84, and at a fraction of the cost you're getting it for a steal. If you have any need for an actual calculator unlike the bull one that comes with your phone; get this one. TL;DR This app is the best purchased app I've ever come across. A true hidden gem.

Great app

The only thing I think that could complete the experience is some haptic feedback. Outside of that, it’s a very well put together app!

Great App

The only calculator app I ever use. Very stable and easy to use.


I highly recommend this calculator. I'm always trying new calculators and this is, so far, the best.

Best calculator app ever

Best calculator app ever

Super good app

You might not be allowed to use this app on a test, but it is as functional as any standard graphing calculator out there. The developer has done a good job implementing all the features and even enhancing the experience with the phone touchscreen. It is not buggy or slow, and the design is well thought out. For me it was worth the investment.

Problem fixed

The problem I inquired about was fixed in literally a day. Can’t beat that! Awesome app.

The best TI 83 emulator

GraphNCalc83 is the best TI 83 emulator I have seen for iPhone. I am going even further, it is even better than the calculator itself!!


Very helpful and convenient! Has all functions of ti-84

Fantastic for chemistry!!!

Not only is this basically a ti-84 calculator, it's also an amazing tool for studying chemistry. It has an entire periodic table that you can select any element and it tells you pretty much every property about it. The molar mass calculator gives you not only the molar mass of any compound but also shows the % mass of each element. A must have

Great calculator!

I love this calculator! I’m a math teacher and have been using it for years. It looks and works just like the old TI-83 so there is no learning curve if you are used to the original. Because of the touch screen to make zooming and tracing easy the graphing is much better than the original and, obviously, much faster. The last update changed the display so that the lines of entries alternate colors, which I don’t happen to care for, but that is just a personal preference. The developer did (does) a fantastic job with this app.

found a bug

This is a simple app but the creators decided to update it so show answers as a mixed number instead of a decimal. This is ok, but a bug was generated in doing this. When I click to use an old answer the mixed number is being represented incorrectly. For example (as shown on app): 255/2 = 127 1/2 255-ans= 191 1/2 The answer should be 127 1/2!!! This is a huge ERROR Either go back to decimal form or fix this please. Edit: They fixed this bug! 👍

The Real Deal

I had a class that required the physical calculator so I was delighted to find a virtual version that I didn’t have to relearn how to use.

Great for higher math

Most useful calculator for IPhone. Works without flaw for everything I’ve done on it. As many functions as a TI-84 but much more affordable and accessible. Couldn’t do my homework without it.
