Got a have it 5/5
As a Machinist this app is amazing for fast calculations.
Favorite computational app 5/5
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
Make sure your in algebra mode though when using x
Not worth the money 1/5
There are many other calculator apps that cost the same or free that provide a vastly superior experience than this one does.
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
History is working correctly after update
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
It has a lot of training videos. I should be able to use it very easy.
Both editions are amazing 5/5
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
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
The program itself seems really good, but there is no obvious help function or tutorials.
Great Calculator 4/5
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 no adds it’s perfect
Fantastic app 5/5
I like the app it is pretty convenient
It fine 3/5
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
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
Love this calculator BUT I wish you could look at all of your previous calculations...
Compares to no other 5/5
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
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
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.
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
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
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
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
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
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
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.
Greater than a lot of things I have been working with.
Ad pop-up 2/5
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
No recent major updates. 5/5
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
I have used lots of scientific calculators but this is the best!
-1^2 is not -1 3/5
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.
Circular button ( bottom left ) 1/5
By Benjamin Ayach
Every time i wanted to click on zero, i clicked on that button instead, please redesign it and change its place
Love it 5/5
Simply the best. I use it regularly to figure out bills and sells tax.
Great for viewing past calculations and easily editing them 5/5

Great for viewing past calculations and easily editing and recalculating them
Inequalities symbols 3/5
By Jon ios
Where are the inequalities buttons?
Infinity calculator 5/5
Too many buttons 2/5
By In PHX Az
Cluttered. Makes noises when entering. Prefer simpler keys mode for routine add subtract multiply & divide. At this point in life .... simpler is better. Apple .. why didn’t you include a 4 banger in iOS? .. they should have! No rocket science required.
By Some kid at midnight
This calculator has everything for school. Definitely worth the money. It even has an entire converting units section. This app has saved me so much time on work. Also has base converter, 2 variable equation solver, 3 variables equation solver, and graphing. True masterpiece for anyone who wants to have a calculator for everything. EZ school
How the heck do you work this thing? I’m stuck in a graph and have pushed every button available but I can’t get out of it.
Good scientific calculator! 5/5
By Stefan ✝️
The Calculator Infinity is a good choice for anyone needing a basic scientific calculator.
I love it 5/5
It is worth to pay for the app it have help me a lot in my maths classes
Nice Find 5/5
When your used to computations your way, this will do...
