Graphing calculator plus 84 83

Calculator which is great, could stand to give a brief tutorial for individuals who are new to ti based instruments. Otherwise it runs well and does what its intended. It however defeats itself by forcing you to buy premium for using features like t-tests. The options are all there, and are justified on premium. I just believe the exuberant features should be premium not half of the stats function.

This app so far seems perfect. I personally haven't used a graphing calculator before but it looks spot on to the ones I've seen. Like almost every other free app, there is a pro version but i don't see it stopping anything for me yet other than setting themes. Other than that, this app is perfect. I highly recommend

Really solid app. Some functions are locked behind a paywall, but the cost to remove is fair. Would appreciate an option to emulate the ti-84's graphing interface (I'm more used to it), but the app's own interface is a lot nicer to interact with. I'd like to be able to adjust the precision of the intersect function on the graphing tool.

Can't believe there aren't more bad reviews on this app. Every statistics function aside from one-sample are behind a paywall. Most basic TI-84 features are not available for free in general. What is available for free are easy enough formulas to do on a basic calculator, on paper or mentally. This makes the free app no better than the default phone calculator in terms of features.

I'm not sure if I fully qualify, as i'm not a mathmatician. It works pretty well, and is in developement. It is free, but will have Ads? I have a physical calc at home too. TI 84 something. Mostly good things, like conversions, big numbers, hopefully it goes well! Oh, I can't forget Premium is $2.99 for life from what I gathered. Seems reasonable :)

So I accidentally broke 2 of the actually Ti-84s, but this app is almost identical and a little more user-friendly sometimes. I don't have the premium version and some things like derivatives, integrals, and limits require premium, but I'd just use SymbolLab online for that. Most phone calculators suck (particularly iphones), but I prefer to use this app over the actual Texas Instruments for the vast majority of the time, and I've been using it for a year now. 1 con: No instant fraction setup

I needed a TI-84 for class and wasn't able to get my hands on one, so I downloaded this. It's functional. There are a lot of ads, which doesnt interfere too much. My one big complaint is that the interface is completely different from a real TI-84 and I can't follow the class instructions without several minutes of desperately tapping random buttons.

The best calculator app!!! It is extremely similar to the TI-84 and it does everything! It can graph, it has options for logarithmic, exponential, and trigonometric functions. It can convert back and forth between decimal and fraction. It also has many statistics options etc. Some extra features are color themes and fonts! I use the neon blue setting. I absolutely love this app and it was definitely worth it to buy the upgrade. 💙

AWESOME! Slightly, different function buttons than a TI-84 but 100% less costly. This app is fantastic if you need the calculator functions without the $150 price tag. Haven't encountered a calculation that it isn't programed to do, just gotta find the buttons for it (and that isn't hard). Ads don't get in the way or distract while using.

Genuinely a life saver for my college math course, it's free, has non-intrusive ads and in-app purchases, and has incredibly good quality of life features that analog calculators and other apps just don't have. It does everything the real deal does, with better processing power depending on your type of phone. If I could rate it higher than 5 stars, I would.

Trying too hard to be used friendly, it no longer is like a ti 84. When I go to polar form, it uses t for time, instead of theta as a ti 84 does. I try math > 9, it won't let me do a definite integral, because it will only do an indefinite, store that, input into y=, open a table input endpoints, and subtract answers from another. Really frustrating. Why can't you just do what a ti-84 does? It already works wonderfully.

Absolutely amazing. While the experience of pressing phone buttons doea not give as much sensory feedback as the real ti 84 calculator, the app takes every possible step to make a fully functional replacement to the calculator. In my use of this calculator, I've never had a problem with obtrusive ads, and I've never wished that I had the physical version. Although phone buttons are more clunky then physical ones, the 100 USD difference between this app and the physical calculator makes it up.

I don't recommend buying the full version. This is a calculator. However, if you were expecting it to feel like your handheld ti84, it lacks many nuances like copying your most recent result, you'll only be able to copy the equation. It has no idea that the 10^2 button doesn't mean add 1 and 0 to the end of a number and raise the whole thing to the power of 2 without specifically telling it. It can do what the 84 can, but doesn't feel like one.

Used it for a bit and I am very impressed. Just one thing. PLEASE PLEASE make the button on the bottom left not have an animation every time you come back to the app (or make it a setting). Its really annoying for people who have OCD or anxiety. Buttons that have animations like that are trying to get your attention. There's no reason for that if I already know what it does. Also have area under curve highlighted

This app is amazing. I tutor math students, many who have access to a graphing calculator in class, but not at home. The features on this calculator are unbelievable. I've used it for hours with one crash. Can be a little slow on complex definite integrals...and sometimes doesn't return a solution...even when one exists. But I'd give 6 stars if I could.

Incredible emulator (and more) in the free version. With the premium version, you ger more features like (more advanced) programming, but the free version comes with most, if not all, of what an ACTUAL 84+ CE comes with, and some nice bonus features. You also aren't *spammed* with ads. Overall a great app to have in general.

One critique/suggestion - give the option to input expressions purely in-line with parentheses etc as with the physical ti83. It is much faster for users who have no issue with order of operations. For instance, I graphed a complicated function, then wanted to graph the absolute value. For that I had to actually cut and paste it into the abs environment, instead of inserting abs( at the beginning and closing the parentheses at the end.
