It’s really useful 5/5
By Christian casas
The is useful for algebra because some kids can’t pay over 100$ for a calculator
No surprises 5/5
No ads or anything else other than a good graphing calculator. The only thing it doesn't have is CAS, but if you weren't planning on using that, this app has everything you need.
Best graphing calculator on the iPhone 4/5
I think that it does a very good job. I like being able to have the graphing calculator on my phone, it does the minimum so if you want it to do a specific action that isn’t that basic you might have to pay. All around I use this app a lot when I need it.
Best Scientific Calculator 5/5
By Bing Brigantic
This is by far the best scientific calculator in IOS. The keys and function works just like the real ti 84. To me it's better and very convenient because you can get this app for free and use it anytime you want on your phone. Best Calculator hands down!
Doesn't have everything that a TI-84 should have
Not free 1/5
The one thing I got this app for, graphing a slope, isn’t free. It’s funny how it’s called a graphing calculator app but you can’t graph a slope. Do not waste your time on this app.
Great App 5/5
By shadow spinner
My graphing calculator died in FST so I found this app to use instead. It does everything that a normal graphing calculator does and I would highly recommended it.
You’re the best 👍👍 5/5
Thanks for free ads
Just like TI-84!!! 5/5
This is exactly like the TI-84 but virtual! It is absolutely free with no ads. The same buttons and functions with a light and dark skin. Couldn’t ask for anything better!!!!!

Total rip off!!! I can do everything on my pre calc. On my iPhone!!!!! Waste of time!!
Inaccurate trig functions 4/5
By bill bob and mando
Graph of sine and cosine function was inaccurate. Their cycles are too long.
This is stupid. All the good stuff isn’t free. Y’all must not be catching onto the trend of human society. No one likes stuff that costs money.
This is literally exactly what you need for algebra this is perfect
I need the diagnostics. Math is too hard and buying a $100 dollar calculator, some kids can’t afford that so they do a math app. I think you should upgrade the app to where we can turn diagnostics on and off.
I need the ability to use the diagnostics
Is was good 5/5
This is a very good. 1/100👍🏼
Does what it does 5/5
Close enough to a ti83 and is totally operable, won’t make your phone self destruct. More than what you can ask for for free.
Very useful 5/5
By Progidy Gamer
It’s a useful app because I don’t have to pay over a hundred dollars to get it and it’s on my phone which is a big plus
Free, great, reminds me of cal in high school 5/5
I like the app and use it for finance calculations in an MBA program
Just like the school calculator!
NOT FREE 1/5
You can do things like 1+1 and it’s free. However, everything else is locked and you have to pay for it!!
You can graph a function but then you have to pay to find a maximum or a root. The app is completely useless without showing me the points I want to know.
Guys don’t waste your time on this.. it’s not free at all 👎
My Students Will Love this!!! 5/5
By Us fam
This is the closest free calculator to the TI84plus calculator. I teach math at a HS. I will recommend this app to my students now instead of Desmos.
With the free version of this app you can only graph up to two equations at a time. You must pay for pro version to graph more at a time. I just delete what was in it and graph a new one. Works great.
No adds!!! In the free version!!! Thank you!!!
I will spread the word about this calculator!!! Keep up the good work!!!
It’s ok 3/5
By Nerd 1.0.1
This app is ok because it has things parts that are free and parts that aren’t. But you would have to download another app that cost about 4.99, but otherwise it’s fine.
Free alternative to the heavy calculator 5/5
I often had my calculator with me all the time! But it isn’t necessary anymore!!!
I got this one! It has all common functions (even including complex and statistics), matrix calculation also works on basic operations! That’s by far the BEST choice you can get for the zero cost!!!
A big thank to developers, i hope you guys’ll carryon well!!!
