Next up we have one for the iPhone readers that was created by William Jockusch.

The reason it is first in line for the iPhone users reading this is because it’s actually a really solid app AND it’s completely free. Yes, you’ve got to love free apps.

And the catch? There are ads on this app, just one really, so not so bad.

But if they are driving you crazy you can pay for the app, cost is 99 cents. So still an amazing deal either way.

This app graphs up to four equations at a time so that you can get your work done as fast as possible.

Some of the graphs it can generate are:

  • Graph up to four equations at once.
  • Graphs are labeled so you can find them easily.
  • You can drag the graph or pinch to zoom in or out.
  • Calculator can find roots and intersections.
  • Graph in polar coordinates.
  • Graph parametric equations
  • Can graph implicit functions, such as x^2+y^2-4=0. Most calculator apps can’t do this!

As you can see, for the iOS phone, I doubt you’ll get a better app at a better price than this.

You can go directly to the Apple App Store and grab yours now here…


Our next pick is for the Android users. And again, we have another free app. The Demos Graphing Calculator has over 5,000,000+ downloads and a 4.7 rating on the Google Play store.

So you know it’s a solidly built app.

Here’s a list of the app’s features:

  • Beautiful and intuitive interface with gesture based control and navigation
  • See instant results of your calculations as you enter them
  • Swipe up on the keypad to reveal scientific keypad
  • Swipe down on the display to see calculation history
  • Support for Samsung Multi Window
  • Show memory keys option
  • Swipe up on the scientific keypad to customize it
  • Create user-defined constants
  • Choose between simple and full keypad layout
  • Choose from a range of stylish themes
