Leave a Review GraphNCalc83
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.
I don’t know how long ago I wrote the above paragraph, but it’s been several years at least. Since they asked, I’ll just say for the record that I’m still using it and I still think it is a great app.Show lessKtscopes
Purchased Back In College - Still Awesome Tool frequent updates
While studying statistics in college, I went to the library and forgot my calculator in my dorm room. I was of course working on an assignment that was due soon and couldn’t go back to my room. This app saved the day!
Fast forward to a few years later, I was tutoring someone and they didn’t have a calculator but were familiar with the TI-84’s layout and workflow. This app came in handy when helping them solve some equations.
One of the best $6 I spent in college and I would do it again today because it’s constantly updated and user friendly. Thank you to the developers for a great app!Show lessHutch1919
Excellent for Statistics!
I teach Statistics at a community college, and our syllabus and textbook require access to a TI-83/-84 Calculator. I've recommended this app to my iOS user students who cannot afford a physical TI. It's got color graphics, something the real TI-83 does not. Plus, it prompts the user right on the command line for the correct arguments needed for a particular Stats function; e.g., for normalcdf, the prompt calls for lower limit, upper limit, mean, standard deviation. Oh, and did I mention the app developer is just an email away and is extremely responsive? You will not regret installing this app on your iPad or iPhone.
It also offers more than one option for conversions between rectangular and polar forms of complex numbers, so essential to AC circuit analysis.Show lessnowradioguy
It just keeps getting better AND .......Most likely It’s all you need and want😃
I have said this before and I am saying it again be because this calculator just keeps getting better. Most likely it’s all you need!
Ohh yess....did I mention the chemistry and Environmental engineering utility! From personal experience this is an ample scientific calculator that can get you through graphing, and bio-statistics,and physics. You will never misplace it, as it is on your tablet and smart phone in a pinch. The programmers care about your user experience, readily offering tips and promptly answering troubleshooting/ how to use the functions. The built help menus are unparalleled. This is one app I won’t be deleting to free up space! Also I think the user interface is extremely intuitive and rich with extras that you simply don’t get with all the handheld calculators that it replaces. Lastly it actually works natively smooth as if it belongs in iOS on your device screen.Show lesshungryspider
Updated review
I have a new device and an updated calculator. I left a review before but now want to update. I enjoy the developer took the time to fix all the bugs and improved the calculator. Math classes get more complicated and it is always great to know with the growing costs of books, school supplies, travel expenses and all things expensive, I am grateful to know there is an awesome developer that takes the time to improve this wonderful application and send all the loyal product users updates at no additional cost. Other developers and book writers would just add pages to a book, or improvements and label it new edition and charge for a new improvement…or more money for fixing the bugs. Thank you for being such an amazing and devoted developer. I will always look forward to purchasing new items in the future. It is also great to be able to review and refresh my math skills on the newly improved Graphing Calculator. Stay awesome!Show lessBrainyWords
i 10/10 recommend this app
I bought this app last year on my phone for algebra because i was having a rough time and rona started so we didn’t have the classroom ones to work with. ever since it has been so helpful and i use it for geometry too. it’s a great app to have and it’s soooo much cheaper than buying an actual calculator like this but still works the same it’s just an app on your phone which also means if for some reason you need to use the calculator for something your going to be most likely to have your phone on you than a big calculator. if your thinking about getting this app DO IT you won’t regret it!Show lesscaylin5200
Affordable for $truggling $tudents
This is such a great app to use instead of a super expensive graphing calculator. I recommend it every year to my students. It’s fabulous for those on-the-spot study sessions at the coffee shop when you have forgotten your calculator. Many of my students have switched to it as their primary calculator. The functions are the same and the control over graph zooming is a simple pinch method. To identify mínima and máxima you just slide your finger over the graph until the color changes. no left and right bounding required. As an instructor, I use it with my iPad and OneNote during lecture. My lecture notes are projected to the overhead screen as I write them in OneNotes. When I need to demonstrate a concept on the calculator I slip it out by swiping left and a small version of the calculator is overlaid on my notes. When I am done, a swipe right allows me to return to only the notes screen. Students are able to watch my key strokes in real time.Show lessHatsemtup
Great!
I haven’t had a chance to evaluate the whole app yet (therefore only 4 stars—sorry!) but it seems to function so much like the ti calculators that if someone needs to switch between this and one of ti‘s graphing calcs, it wouldn’t result in much getting used to at all. That is a HUGE plus. Students can practice with this App and then be better prepared when they are limited to an actual calculator for school or taking the SAT or some other testing purposes. I find it absolutely excellent that students can have access to a calculator like this without having to pay over $100 for an insanely cost prohibitive calculator that is only really worth about $15-$20, if that. After 20 years in math education, I could say so much about that racket but will refrain.Show lessMaffTeacher
Wonderful, Powerful, and Free
This app is great!
I’m a student and often use a TI-84 Plus CE which costs 100$ plus. This application seems to have the vast majority or possibly all the same mathematical functionality as my TI calculator and is totally free. In addition the layout and design of the app seems to take some hints from TI and other purpose built graphing calculators. This made it easy for me to use coming from a TI calculator. The app also improves on many of the monotonous annoyances that come with using a conventional calculator. By this I mean things like scrolling through lists, finding intersections on graphs, moving your cursor etc. A lot of these are solved since you can simply touch what you want to interact with as opposed to clicking away with the arrow keys that are featured on most graphing calculators. Finally the app runs much faster than a normal graphing calculator while not requiring an internet connection like Desmos and other free graphing services out there.
Overall it’s a great app and I highly recommend it. If you need a capable phone calculator, I would give this app a shot, It’s free so you don’t really have anything to loose.
Sincerely,
A happily surprised student :)Show lessMic_AR
Awesome++
I have been looking for a truly powerful calculator for a long time. I've tried variations of the HP top of the line and several were very nice but as I said in one of the other reviews that calculator emulators are great for what they are but the idea is to serve your needs. If a calculator still retains all of the disadvantages of the original then it is not an advancement. This calculator not only provides all the capabilities of the HP that inspired it but also eliminates many of the physical calculator's cons. Ever had a calculator that did everything you needed and more but required a book and a lot of memory work to do any of the sophisticated things? This one does not have that drawback. There is context based help available at the touch of a button. Now you can actually use the full power of the calculator without it becoming a research project. To me, that essentially made the more advanced the calculator the less useful it became. Not so here. I applaud the developer. We don't need exact replicas of calculators, we need something to do a job with the least effort on our part. This is a giant step in that direction.
On top of that, the developer continues to add additional enhancements without resorting to “forever pay”. This is truly a rare gem.
Calculators are not sacred but my time is. Get this. You won't regret it. Now I can get on with my work!Show lessowndao
