Upgrade to Solve Pro and plot graphs with a single touch!
Solve Pro is available as an in-app purchase for iPhone & iPad.

Solve Pro plots 2D and 3D functions using the x, y and θ variables. When you use these variables in an equation the output will change to Touch to Plot.

Plot 2D functions using the x variable.

cos(x)

sin(x)

x^2

abs(x)

x^2+2x+6

Plot polar equations by using the x and y variables.

2θ

sin(2θ)

Plot 3D functions by using the x and y variables.

cos(x)+sin(y)

x^2+y^2

Graph multiple functions by separating each equation with a comma.

sin(x),cos(x)

x,x^2,x^3

The T variable is used to create animated or time plots and can be used with both 2D and 3D functions.

cos(x+T)

sin(x+T)*x

cos(x+T)+sin(y+T)

I am totally humbled by Nicholas Prieve

This is amazing...

Wow! by Eli Kane

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!

Wow by kcmac1

Just discovered this gem. Great touch interface. Love the memory function using separate calculators. Ability to see equations and easily edit them very intuitive.

Awesome! by smart-music-fan

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.

Insane by A Google User

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!

Fantastic by xTricksterz

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.

Great! by mmonagha

Intuitive, innovative, and useful. Great app!

Awesome!! by Donniew84

I just love it!

Excellent by Hamster at Dawn

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!

Awesome!!! by llikeadodachacha

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!)
