Great price but a there is a flaw
I am giving this 5 stars because compared to purchasing a ti-84 it is fantastic. A ti-84 is around $120 while this is only $6. We have ti-84s at our school and I prefer those because of the buttons being easier to use and press but they can do much about that because this is a touch screen phone. The one flaw I have found while using this is while zooming in closely to a line on the graph sometimes the line will move or extend a bit while I am zooming in then it will change positions when the zooming stops. I was graphing circles and just messing around with the app when I noticed this. I put y1=-sqrt(64-x^2) and y2=sqrt(64-x^2) and I noticed as I zoomed in to where they should presumably meet along the X axis they were messing up for me. Otherwise amazing app and I believe they actually have more features than a brand new ti-84.
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.
This calculator is loaded with everything and actively working for enhancements continually
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.
PERFECTLY DESIGNED AND IMPLEMENTED GRAPHING CALCULATOR!!! Best app ever, best graphing calculator ever -- bar NONE!!!! I cannot believe I have been hauling around my bulky "ti 84 plus c silver edition" (for 2 years) when I could have been using this app. i cannot believe I have taken five junior college math courses (int algebra, trig, precalc algebra, nature of math, finite math) and no one has told me about this app. I cannot believe I have suffered with not being able to easily see/know window mins/maxs and have labelled tick marks while looking at "graph." This app is what the physical ti graphing calculator SHOULD be doing, but cannot, because ti graphing calcs dont have a touchscreen like our smartphone!!!! With this app and the wolframalpha app, I can do anything. (Please make a CAS calculator, too!) I wish i could give the rating of INFINITE stars...
Best thing ever made for the iPhone!
I absolutely love this app! Ive had it for years and I still use it every day! I love all the new features! One complaint I do have about the newest update is that the older versions let you simply click your previous calculations and it would copy it right into the place where you are typing ! that saved me so much time especially when they are really long numbers. This new update isn’t letting me do it anymore ? Is there some way to turn it back on? If there is and you are reading this please let me know ! But if not I hope they add that part back in the future update, besides that this is the app MY iPhone was invented for ! It is amazing !
Great for a Stats class
I downloaded this for my Math 103 class and it worked fantastic. Colors, capabilities, zooming in and out, just limitless in my opinion . Although it was hard having to use an archaic piece of plastic in my proctored exam. I am so surprised that graphing calculators have not changed at all since 1998 and they are still so expensive. I’m hoping soon the colleges will adopt policies that allow us to use this technology such as this app. You would think that if were being video taped in a proctored exam that we could use this program and not the junky piece of plastic they provide.
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 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.
Love to use in classroom
As a trig/pre-calc teacher I love this app! I use notability on my ipad to project notes (SO much better than writing on the whiteboard) and can easily go back and forth between this and notability to show them graphs, how to enter things into their TI calculators etc. My graphing calculator is very old (I taught years ago then took a break to be home with my kids and recently started teaching again) and this is so much better than carrying it or buying a new one that has color. Thank you for creating this!!
I have been using this for two years. As a Math and Science teacher, I love the versatility and the fact that I always have my phone with me. I use a TI84 regularly and like this app better. The reason for two stars is the last update. I use the conversions tab an awful lot and it has stopped working. I can no longer choose my options. This gets fixed and I’ll definitely be a five star person. It was as simple as getting in dark mode. Easy fix and all is good!
A Really Useful App
I discovered the TI-83 Graphing Calculator a long time ago, and reached for it to do lengthy calculations frequently. When GrafNCalc83 came out I was very excited about it since I could now do the same calculations on my iPhone. But it was missing a convenient way to create Programs - until now. I can’t wait to create some programs that I use frequently. Many thanks to the author for maintaining this App AND for adding all the new features. If you use the TI-83, you’ll love this App, and you can leave your TI at home.
Awesome features and constant updates make this a must buy. The developer is super active, and responds to questions quickly. Many times I just need a graphing calculator and this is the only thing I ever go to. It’s literally a few bucks for more features than an actual graphing calculator. If you need something fast and easy, go with this. You won’t regret it. If you need any help, there’s instructions for each function and if that fails, the developer is fast to respond. Awesome app!
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. There is no drawback to this app. I wouldn’t go back to a real graphing calculator, though a graphing calculator has real buttons. I use this app all the time. For me it is worth the investment.
Better than a graphing calculator
This app is better than a graphing calculator due to the touchscreen capabilities. It is also much cheaper than a brand new TI-84 ($6 vs $120). As a HS math teacher, I allow my students to use their cell phones on many assignments. I recommend this app (and DESMOS) to any student that plans on using their cell phone to analyze math in and out of the classroom. I also love it since now I do not have to carry around a graphing calculator since I always have my cell phone with me when I teach and tutor.
Math Prof says : SUPERB TI-8x emulator for iPad and iPhone
I am a longtime math teacher who loves this app. As other reviewers have said, it is better...much better...than any of the TI-8x models on which it is based. Easier to use..better display...better graphing...better! Texas Instruments keeps trying to get us to upgrade to more expen$ive calculators with increasingly needless and unuseful "features". Why? This app turns your iPad/iPhone into a super-TI-8x calculator...at about 7% of the price! If you like and use the TI-83/84 models, this app is highly recommended.
