Calculator ∞ app reviews

  • Homework helper 5/5

    By TimTimpani
    Fantastic for checking answers on my kid’s homework!
  • Great but confusing. 4/5

    By Dingus-Doofus
    I have had this for about a month, using it for advanced math but I can’t find pi, so I was wondering where it was. I would give it five stars if it wasn’t so hard to find, other than that I highly recommend this if you don’t have a scientific calculator.
  • I’ve tried a lot and this is my favorite by far 5/5

    By qwerty ytrewq
    Clean clear intuitive and shows past equations and can easily tweak old equations and get new answer
  • Good 5/5

    By islam dowidar
  • My primary calculator 5/5

    By 7m1234
    I use Calc Infinity as the primary calculator on my iPad. For only 99¢, it’s a really good deal!
  • Fantastic app 5/5

    By gregassa
    I’m loving it🤩🤩
  • strange implementation, help w/ many limitations 3/5

    By whatamesswithnicknames
    At first glance it looks as if this calculator has everything you need, next you realize that it differs a lot from conventional calculators. The symbols used are strangely inconsistent, just try and use the key X and the X2 (square) and compare what happens. Help is utterly incomplete and rarely explains more than what is obvious anyway. A split screen help ( showing the calculator or part of it, and help next to it ) would make a real difference. This app hasn’t seen any updates in a long time. Don’t waste money on it.
  • I can set this perfectly 5/5

    By SecretAnime
    I can tune this perfectly to what my instructor wants.
  • Nice 5/5

    By Jackson's Ghost
    It let’s me use my mathematics training without having to relearn everything. Very nice and most useful
  • Wow! 5/5

    By SuziQuay
    This is slick. I’m still learning to use the functions, but what I have had to solve in trig I’ve been able to do on this calculator by using intuition ( not the manual) that’s good.
  • Not giving me the answer 1/5

    By special steel
    I paid 3$ use this app and it is only giving me a hint not the answer
  • Great Software 5/5

    By Peter Sramka
    Powerful and easy to use.
  • Got a have it 5/5

    By Dhewik
    As a Machinist this app is amazing for fast calculations.
  • Favorite computational app 5/5

    By TechSpan
    As a scientist, I love this app. It is populated with algorithms useful to a scientist, allows recall of previous computations, supports a series of computations for tracking purposes, and has a look-up table for scientific constants. The app has replaced my scientific calculator, but not my more advanced computational software (I.e. MathCad, Mathematica or MatLab).
  • It great 4/5

    By Michelleedward
    Make sure your in algebra mode though when using x
  • Not worth the money 1/5

    By calvinbrodice
    There are many other calculator apps that cost the same or free that provide a vastly superior experience than this one does.
  • Excellent 5/5

    By DeMachiato
    Far and beyond my expectations for th price (I bought the Bundle $3.99) I couldn’t ask for more.
  • The calculator is wrong 1/5

    By Typhoon Actual
    I am revisiting my college algebra through a course at ASU on EdX. While working a problem I raised -2 to the 4th power and got -16. The correct answer is +16. After several tries and always getting the same wrong answer I tried the square function. -2 squared resulted in -4.
  • Missing history (Fixed) 4/5

    By Somps
    ***Update*** 2019-07-14 History is working correctly after update 2019-07-14 Works pretty good but when I went to look for history, there wasn’t any. I will update the app and check it again.
  • A calculator from the gods landed in the App Store! 5/5

    As if godly tech from god-like forces just falls from the skies, right into my hands every time I open the app. You have my sacred and hard-to-get approval. Call it a godly certification, if you will.
  • The calculator has a lot of functions. 5/5

    By Babrother
    It has a lot of training videos. I should be able to use it very easy.
  • Both editions are amazing 5/5

    By _Fonzii
    Started out with the free Calculator # and later upgraded to the full version. Both calculators are powerhouses of phone apps that are a must have for anyone who ever needs any kind of calculator on their device. The apps are very intuitive and extremely well made, and support a wide array of options making life so much easier. Highly recommend to everyone.
  • Contains advertising for Android version of the application. 2/5

    By RayReichard
    Any time you have to click a button to clear part of the screen (Android ad) it's annoying.
  • Lots of power No directions! 3/5

    By bloorg27
    The program itself seems really good, but there is no obvious help function or tutorials.
  • Great Calculator 5/5

    By #Ray$41
    A really useful scientific calculator that I use daily in my work. By accident I entered 0 to the 0 power and got 1 for an answer which is the wrong answer. Makes one wonder what other bad math is in this great app. I would give it a 5 if not for this error.
  • It’s getting slow 3/5

    By Camilo Calvo
    This calc was the best one on the appstore but I’ve seen it’s getting slower with every update
  • Awesome 5/5

    By GOATidiah
    Awesome no adds it’s perfect
  • It fine 3/5

    By beastmasterr69
    If u don’t really how to use it, use google calculator it kinda better, don’t waste ur 1$
  • I go to MIT and use this app DAILY 5/5

    By Polevata314
    The title pretty much says it all... This app has been invaluable to my studies, and it has a ton of useful features if you start to snoop around. Having explicit constants from all corners of physics, math, and chemistry is so helpful! One thing it's lacking is in graphing abilities. The graphing utility is very limited. That said, Desmos exists if you really wanna graph something beautifully. A final feature suggestion would be a single app mode with a timer. I use this so often, i haven't really needed a calculator since i got here. The one exception is during exams and tests. If it had something similar to what Desmos has where you can't exit the app, and you'll have proof you only used the calculator at the end of the exam, i could probably convince some professors to let me use it! Overall wonderful app that is a joy to use, and definitely worth well over whatever i spent on it back in high school!
  • Good but it needs a scroll function 4/5

    By Alor500
    Love this calculator BUT I wish you could look at all of your previous calculations...
  • Compares to no other 5/5

    By Wharffy
    After searching and using many algebraic calculator's, this is hands down the best and most intuitive calculator on the app store!
  • Excellent Set of Calculators 5/5

    By jegree
    The combination of calculating systems incorporated in this application allows efficient work in a variety of disciplines that is unparalleled.
  • Easy to Use and Efficient 5/5

    By bpcger34332
    The way this calculator allows you to enter calculation formulas in forward form (e.g., sin 45 instead of 45 sin; -1 instead of 1-), and how it understands notation shortcuts such as 4 pi = 4 times pi makes entering calculations much more efficient and much less error prone than traditional scientific calculators. You also see a scrolling display of your total calculation entry (instead of the display refreshing with each intermediate calculation value). This helps you to check that you entered a long calculation correctly. Highly recommended.
  • 👍👍 5/5

    I bought the bundle and they work great. I never have had a problem with any of the apps
  • Do not buy this app 1/5

    By Tung Ro
    Pls, remove Android Version adv in Main menu. I buy pro version but it still has adv in settings menu.
  • Good calc and converter 3/5

    By fr3dr3rik
    I found this app very useful, have a nice interface, a little complicated to use, but nice. The only thing that annoys me is the ad where developer offer same product for Android. Please remove that ad.
  • Nicely done, particularly “Conversions” 5/5

    By jamesgate
    Lots of calculator features in one package, Base mode (hex, octal etc) and Conversions (baking!) are very nice to have; many “Constants” too; use this daily.
  • iPad pro 11 1/5

    By A Hero.
    The new layout for iPad pro 11 feels out of proportion, It needs to be changed asap.
  • What I’ve been looking for. 5/5

    By TheDiamondSunset
    This calculator is well worth its money. It has so many useful features that it’s insane how little this costs. Also, this calculator has the one feature I’ve been looking for, and that is to be able to input a variable anywhere into an equation and it will solve instead of the long process of rearranging the equation to solve it. Also has a great converter, and other useful modes.
  • Complex Numbers 5/5

    By Vinhkan
    Well I’m new with calculator but it’s really making short work complex math. It will take rectangular and polar equations mixed and give the result. Also going from rectangular to polar is one key stroke. So far I’m liking this calculator a lot. More as I go along.
  • Best calculator ever! 5/5

    By Malbec03
    Calculator infinity has very cool features, you can do 10x10=y and the calculator responds y=100 even like, hard math problems it’s like everyone needs to download! I rated 5 stars because it’s just too amazing.
  • finally i found 5/5

    By Massage mania
    this is the only one that engineering student definetely will love. i have paid and looked around a lot, finally this works great. i do long complicated calculations, it is as good as my pro eng calculator. i love it thank u
  • 🙏🏻Please add The Functions Sec, Csc, Cot 4/5

    By Delta_Sqrt(-1)
    I know that it can be defined with cos, sin, tan, but sometimes it becomes tedious to be defining it like this when there are long trigonometric problems.
  • Yeah 4/5

    By farshinto
    Greater than a lot of things I have been working with.
  • Ad pop-up 2/5

    By adonisehiwario
    I don’t know why there’s an ad pop-up for a paid version of this calculator. Whenever I go to setting its displays this: Android version available. How the hell is that my business?Please do something urgently about it.
  • Piece of junk 1/5

    By DevoBillado
    Horrible calculator
  • No recent major updates. 5/5

    By iGonerose
    This is the best calculator app in the iOS market, but its missing updates recently. Just stability fixes... I wish there were better graphing options, for like cubic functions. And increase function limits to be plotted on graphs. Thank you developer for this beautiful app. Worth the penny.
  • Best calculator ever! 5/5

    By QueteQue
    I have used lots of scientific calculators but this is the best!
  • -1^2 is not -1 3/5

    By Unlock6789
    Please fix the fact that negatives to the power of even numbers come out as still negative, it really screws up a lot of my equations.
