Amazing app!
I’m an educator and the good this app has done for some of my students who can’t afford a calculator is inestimable
Yeee
It’s tuff
Why?
Everything is locked behind a paywall, Why even pretend it’s free?
72.4 times cos(58) is not 8.62 it’s 38.36
72.4 times cos(58) is not 8.62 it’s 38.36. I checked google and apple calculator
Wrong answers for exponential equations
When I entered “Ans^-10”, Ans being 1e-1000; The wrong answer this gave me “1e-10000” instead of the correct “1e10000”. I noticed this many more times before while calculating big numbers like that, before crashing.
Otherwise, this is a great calculator app, and I hope to see it get better!

Y’all took away ad free for early adopters.
Restore purchase doesn’t work either. What a shame. That deserves a 1 star.
has saved my life

Lagging past week
I love this app so much. I have a shortcut to it on my phone home screen, have told my friends to download it regardless of if they need a calculator app, etc. I have an average 30+ mins of screen time on this app alone for every calculation I need to do... until this past week. Out of seemingly nowhere, 5ish days ago, the entire app has been extremely slow. Like, type a number in and it shows up on the screen seconds later. Nothing else on my phone has been affected. Calculate84, I am one of your biggest fans, and if this issue is resolved I would love to update this review to the 5 stars you deserve.

literally can calc big numbers
great job
Was convenient, now slowed
The app was a great convenience when I downloaded it a couple years ago. But lately, the app feedback has been significantly when I’ve tried to type in numbers. It has become more of an inconvenience due to the delay, sometimes lack of response.
Really Useful
This calculator app is very useful for homework
Best calculator app
All functions of TI-84 for free. A lifesaver for broke high school and college students
Close enough
Easy to use but not like the actual calculator on some parts
Exactly what you pay for
It works exactly like how you expect it to. It’s literally a full fledged TI-84 calculator that’s on your phone. You have to pay the 30 dollars to actually use all of the features but that’s way cheaper than ones you can get at the store. This is a must have for anybody in school
Awesome!
This calculator is great I love how much it resembles the hand held version but I also really appreciate the little updates that allow you to edit your equations more easily than the hand held TI84 (or at least the one I have). This App is great I would highly recommend it.
5 Years in and Still my Go-to Calculator app
Way past school age at this point but I still use this for all my calculating needs.
A definite must-have for any smartphone user

If you are an iPhone user and need a calculator that is simple and easier to use with Trigonometry this is it !!!
Amazing
Works just like the real thing!
Be
This is the best calculator I’ve ever used. It’s great for decimals, fractions, numbers and so much more!
Weird
Kinda weird layout
