This calculator has amazing functionality, and the developer is a saint. Thank you! -- XTF87, 2025-02-04 ### ***** "Great Calculator" Excellent calculator with frequent updates; it’s been the one to get me through college -- melyyyyyyyyyyyyyyyyyy, 2025-01-21 ### ***** "Great interactive plotting (with no data collection'" I love this app. Now, I *was* completely unfamiliar with TI-83 calculators, and for someone like me, the interface can definitely be awkward and unintuitive. I can put up with that. What I love is GraphNCalc83's flexible, interactive control over plotting. It's a great tool for exploring mathematical ideas on an iPad or phone when these are the only devices available. When I bought it, the competitors either didn't do what I needed, or required me to agree to letting them collect data from my use of their app. GraphNCalc83 doesn't do that. I've been using it now on and off for a couple of years now. Well worth the price. -- Mxba99, 2024-12-22 ### ***** "Best calc for iPhone" Like many, I spent years in the past using TI-83+ at school, the TI-89 Titanium in more school. Decades later, when I found the built-in iOS calculator lacking, I tried all the ones in the App Store and this one is by far the best to me. Lets me do everything the best, even though I use it for basic purposes. It is so logically and beautifully implemented. It is capable for far more than I currently use it for, but the most important things are it can do everything the way a calculator should. Bravo, and, please, I beg of you to keep this maintained and available as far into the future as possible. Amazing. Feeling very grateful. -- Notasev, 2024-12-15 ### ***** "Excellent graphing calculator" This calculator is both versatile and easy to use. For anyone used to a popular stand alone calculator, this app is an easy transition, as well as being more convenient, since it is always with me. I have used a couple other competing apps, but this is the one I kept. I look forward to using the new math typesetting feature. With every new version, the calculator gets more powerful, while maintaining its ease of use! Thanks for building this app! The improvements continue and I continue to use the app even in retirement. -- Hcmath, 2024-11-26 ### ***** "Excellent replacement for my TI84" It’s great to be able to have this TI84 in my pocket at all times. -- JacksForge, 2024-10-12 ### ***** "Amazing!" I am an AP Calc, Stats, and Precal teacher and I teach with this from my iPad and recommend it to all my kids. Most valuable app I own! Plus you have to give the developer props for not doing this ridiculous subscription nonsense! -- Peppered_Beef_Jerky, 2024-10-10 ### ***** "Great Scientific Calculator" Very handy technical calculator. Graphics work great! -- Vince3141, 2024-10-10 ### ***** "Great app with a nostalgia factor" Very functional calculator app that does things my old graphing calculator wishes it could do. The appearance is tidy and based on the most familiar graphing calculator designs of the past 30 years. Don't mess with success! Thank you to the developer for creating a highly functional app with no micro transactions and no spyware. -- Fantasoap, 2024-10-06 ### ***** "Great for Nuclear Engineering" Straight up, this calculator emulator has been by my side any time I’ve had to run calculations. From statistics to finding the material properties of uranium dioxide at different temperatures, this app has been my go to. I’ve preferred this over desmos, wabbit.emu, and only ever pass it when I’m running python script. I really wish I could have a desktop version of this app, because it’s so good that I’ve instinctually come to pull my phone out whenever I need to do anything more that four function calculations I literally wouldn’t be able to do my job and do my part for society without this app. So in great sincerity, thank you -- Raven C. Corax, 2024-10-03 ### ***** "Helpful tool" It’s really helpful and functions are incredible. You can explore and make all type of serial numbers and give you the answer. Easy to stick with the app. -- Vickycortes, 2024-09-19 ### ***** "Best calc app out there" Does everything you need from the basics to graphing. This is my go to calculator on the iPad. Great app! -- notDaStig, 2024-09-14 ### ***** "A must for my college students" This calculator has everything (and more) for my intro to statistics college course. Most of my students use this app on their iPads and find it more user friendly and more powerful than any other apps out there. Thank you for this amazing tool!!! -- ProfCarter, 2024-09-12 ### ***** "Love this!" Very practical for my everyday use. Quite often I use the stats function to determine if data displays a linear, quadratic, etc. function. -- Brownmath, 2024-09-09 ### ***** "Exceptional" This is an exceptional calculator. Once you get familiar with the built-in functionality it is a powerful tool. Absolutely worth the cost. -- Spectrosmith, 2024-09-09 ### ***** "Better than a physical graphing calculator" I’ve used this app for over 6 years. I say it’s better than a physical graphing calculator because of the ease of using a touch screen to interact with the graphs. Zooming in and out is easy, finding intercepts is easy, as well as finding inflection points/ local maxes and minima. When I updated my phone, I was sad to see that it wasn’t working, but I just heard about the update and am so glad that I can continue to use it over the native calculator that Apple provides. I’d highly recommend it to any student! -- Person_007, 2024-08-07 ### ***** "Very good program" For work and school -- Lfh0823, 2024-08-05 ### ***** "SAVED ME IN STATS CLASS" This app literally got me through statistics! It was a stressful class but this app function definitely helped to ease the stress. Thank you for saving my butt lol! -- Thetruthteller100, 2024-08-05 ### ***** "Great Free Tool for Students" I have been using the this app throughout my college years. It’s suitable for my calculus and chemistry classes. Most importantly it’s free and ad free versus an expensive scientific calculator. Its comprehensive functionality makes it easy to use. Recommend for college students. -- DynamicPanda888, 2024-07-13 ### ***** "Updates" I appreciate getting free updates -- Math Nerd #2, 2024-07-11 [View all GraphNCalc83 reviews and detailed analytics on AppTail](https://apptail.io/ru/account/signup?utm_campaign=ai-crawl&utm_content=reviews) ## GraphNCalc83 Store Rankings | Chart | Country | Category | Rank | |-------|---------|----------|------| | Топ платных | Пакистан | Education | #201 | | Топ платных | Беларусь | Education | #400 | ## GraphNCalc83 Discovered Keywords -
