It does everything I need in a 'fun' way that's intuitive to how I think and operate. I'll take it!

This app is not only comprehensive, it's also fun!
Best Calculator in app form!
by Joseph Coleman
This is the sleekest, powerful, calculator I have ever used! Well deserving of my 5 star rating!
Clean interface with useful features
After trying many different calculator apps, this is the first one that has actually replaced the default iPhone calculator for me. It is perhaps a bit more colorful than needed, but the extra colors pop out and make it a more pleasant app to use. The memory features in the app are amazing for people who do repeat calculations using the same numbers.
Wonderful design makes it feel easy to use

This is a great calculator, aesthetically and functionally. Having the answer appear as you enter numbers will be the future of all calculators.
I love this calculator
I work on a shipping dock and it saves me a lot of time and headache. I can have 4 different calculator in one place. I can see the different weights or counts and know where I am if I have to do a lot of weighing or counting on different pallets. I use it every day. I also use it while shopping and can add the price of my shopping list and calculate what things cost. I love this calculator.
What the iOS calc should be!
I love how it can keep track of all my numbers in a long equation, just like back in the days of the graphing calculator.
Just what you need
Does exactly what it should and nothing else. I like the multiple tab feature and easy number storage. Nice work!
by Pablo Enrique
Intuitive and a pleasure to use. Makes long, tedious calculations simple with the ability to store and retrieve previous answers in just a few swipes.
I am totally humbled

This is amazing...

Best graphing interface I have used so far on Android. Love the inclusion of graphing over time- really expands understanding of some functions, especially ones tied to physical phenomena. Outstanding and worth every penny. Thanks!
Just discovered this gem. Great touch interface. Love the memory function using separate calculators. Ability to see equations and easily edit them very intuitive.
This app is great. It easily graphs functions on the xy plane, and adding T as a variable to make the graph move is so fun. Its 3D graphing capability is great - quick, easy (it sets nice bounds on the z axis so you can see things clearly), and helpful for visualizing my Multivariable Calculus homework.
This is my go to calculator. I love that it has four screens so I can do different things without losing my place. It's also as much scientific calculator as I need.

It is stupid how excited I am about a calculator right now.

Wonderful. It's really easy to use. The concept of working with four calculators at the same time is really great. What a pitty most android users want everything for free. They will miss this masterpiece.

So well thought out! This calculator app is the first I have seen to really take advantage of a touch screen environment. The controls are intuitive and the graphing options make this seemingly simple app quite powerful. The best feature is that the app runs four calculators at once. A complicated function can be broken apart across several calculators and then reassembled by dragging the components into one equation... Amazingly useful!

This app is beautiful, I use on my iPad and I'm first to answer most of the problems in class. This app shreds TI's calculator OS.
Intuitive, innovative, and useful. Great app!
I just love it!

This is a very good calculator, it has all the functions you need for A levels and more. The graph drawing is so much fun since you can draw 3D graphs and even graphs that change with time. It also does it all instantly unlike conventional graphical calculators that can be painfully slow. Ten thumbs up!
Does just about everything my TI-84 Plus but quicker and much easier to manipulate the graphs. It loads instantly and the 3D function is awesome for higher level math classes (I'm in Calc 3 now and it's already come in hand!)
Plot 2D functions using the x variable.
Plot polar equations by using the x and y variables.
Plot 3D functions by using the x and y variables.
Graph multiple functions by separating each equation with a comma.
The T variable is used to create animated or time plots and can be used with both 2D and 3D functions.
