Proper calculator - works well
I tried a few calculators for the iPad which were frankly rubbish but this one is the business. The user interface is fine but could be slightly streamlined - but it’s worth the money.

Very helpful
A very useful app with both helpful and interesting features.
There is though something missing, the conversation of base numbers. Even if it's just Hex, Binary and Denary please add it!

Really useful all round calculator
Best calculator I have found for the iPad. It does the job and has advanced functionality for the odd occasions I need it. In my opinion it is much better than any traditional calculator as the different usage modes are separated out which means the keys are not overloaded with functions e.g. When I'm working with binary I am usually not interested in trig functionality. Also, love the graphing and root solving functionality for when I want to quickly check something.

Great calculator
For day to day and scientific & engineering needs this is A+++
2017-12-18
Bang on...!!!
Lots of features, does what it says on the tin! Great app...

Very good app!
2017-09-21
Calculator: great product
Finally delivers functionality I used to be get with my old physical scientific/programmable calculators. Great...
2017-09-02
Top Calculator
I use this app all the time. Had a few different "paid for" calculator apps, and this has been the best.
2017-08-02
Well Designed
Still familiarising with the app but it is well designed and intuitive.
2017-07-19
Works well
Great calculator but takes a bit of getting used to. Would recommend.
2017-03-16
Great
I love doing fractions with this calculator
2017-03-08
Cool calculator
Superb just wish my maths skills were as good
2017-02-16
Great scientific calculator
SUPERB!

Disobeys Volume (SOUND)
My iPad is on mute but it still makes sound. Fix it for ⭐⭐⭐⭐⭐. Gets the job done tho
2017-02-13
Best calculator ever!
This is easily the best calculator app for iPhone or iPad, and is well worth the asking price. This app does all I need and far more - i only just found out it does unit conversions, which is a huge bonus!
2017-02-02
Brilliant
An excellent calculator, the closest you'll get to a Casio on a phone, easy to use and with heaps of functions!
2017-01-03
Kev
Good calculator and converting app in one.
2016-12-30
Excellent
This is easily the best calculator app I've found for the iPhone. I don't use anything else now.
2016-12-21
Amazing
Very happy with this app
2016-12-19
Excellent
As a part time Maths degree student this is the perfect accomplice to digital copies of my study text - as good as the 'staple' Casio calculators. Could do with landscape view as an alternative to having to swipe for additional menus but overall excellent.
2016-11-08
It's good yeah
Do it. It's good.
2016-10-15
Very good calculator - FX83/85 equivalent
This calculator has similar functionality as a Casio Fx83/85 series of calculators but at a fraction of the price.
Only improvement needed is between switching screens. I have stopped using the swipe technique and the functions I want are always on the other screen. Being able to define which functions you have on each screen would address this.
2016-10-13
Good Calculator
I gave it four; but would have given it 5 if had more stat's applications. Nevertheles, I would recommend it to anyone who wants a good calculator on their phone or iPad.
2016-10-06
Excellent calculator
Excellent calculator,
Just a couple of thoughts
you need to be able to edit the x and y ranges for the graph and not keep then fixed, for example plotting sin(x) on the graph, the x range is -360 to 360 the y is -1 to 1 or even have an auto fit button, for most graphs people will know the x range that it is to be plotted over, calculate the results and then display. That way we don't have to change the graphs to 100sin(x) just to see them.
Also make use of the nice hires displays and have a thinner line or select line thickness and a landscape mode for the graph.
2016-10-05
Brilliant
Easy to use, glitch free and feature rich.
2016-09-17
Exactly what I wanted
As a mathematician I constantly need a good quantity calculator at hand.
This does exactly what I need.

Infinity calculator
Excellent calculator. iPhone version great too. Loads of different functions for every problem.

A complete calculator with lots of features that are easy to get to

Great Calculator
This calculator is brilliant and is very easy to use.
It is an inexpensive scientific calculator and contains every function you need.
2016-05-15
Great app
Great app for teaching and using as an emulator.
Could really use tables mode in algebra though.
2016-03-19
Excellent software
I threw the indefinite integral of Sin(x)*Ln(x)dx at it and it neatly brought out the complex numbers involved in the answer.
2016-03-17

Very useful calculator

Maths calculator
Good calculator
2015-09-06
Really good calculator app
I'm over 50, an engineer, I need a calculator like the one I used in my twenties akin to the Casio fx-991. This calculator app does the job, and some. Nice touch!
2015-06-28
Good, could be better
Great multipurpose calculator. Only knocked off a star because it was pestering me to rate every minute. Would also like to see some calculus functions introduced. Then I believe this app would be the best all round calculator.
2015-06-02
Best calculator around
This is the best and most complete calculator for iPhone well worth it!
2015-05-29
Best calculator app
Have been using for over a year and have been very impressed.
2015-05-24
I don't much care for being nagged to rate 30s into using an app…
…any developer which nags me to rate almost immediately gets an instant 1 star, no matter HOW good the app is (although who can tell after less than a minute…?!).
2015-04-26
Great app
10 years ago you'd have had to buy a vastly expensive graphical calculator to do a quarter of what this one does... Excellent and powerful.
2015-04-23
Glad I bought this
Really nice to use.
Love it.
2015-03-25
Excellent
As I said, excellent :)
2015-02-22
Does what it says on the tin
This is just a really nice app to use. I have a large expensive graphing calculator, computers with the language R installed for maths and stats but also an iPhone so when I just need a calculator, this app comes out.
2015-01-04
Great calculator!
I'm just starting to restudy high school maths at the higher level and this app seems to be just the ticket :)

Best Calculator
As a maths teacher I have looked at quite a few calculators. This is by far the best one as it has "write view" as standard.
