Graphing calculator turned on its head!

Instead of typing functions, simply draw the graphs you want and let FuncDoodle work out their formulas. Tap on any line to see its function, then watch it move and wiggle as you slide the parameters. We hope you’ll agree that doodling function graphs in such a direct and free-flowing way makes FuncDoodle a smooth drawing app!

We invite you to surprise us with some cool math art as well as to share it with your friends and teachers. We are looking forward to featuring the coolest (and the cutest) at FuncDoodle.com!

After having fun with FuncDoodle, functions and graphs you encounter at school will no longer feel intimidating but familiar and easy to master. More and more teachers encourage their students to play creatively with graphing calculator apps and compose pictures out of function graphs. There are thousands of wonderful examples of such artwork on the Internet.

Of course, graphing calculators are not designed for this, so making an exciting drawing involves painstakingly typing out a function for each and every line. To our best knowledge, FuncDoodle is the first app that was designed especially to make doodling functions a joyful and engaging learning experience.

With this first version of the app, FuncDoodle can already recognise three classes of functions, which together allow for a wide range of expressive strokes:

• polynomial
• elliptic
• sine

* Note that the first two classes include most of the conic sections - i.e. circles, ellipses and parabolas.

As you can imagine, we are dying to hear from you!

FuncDoodle is a new kind of app and we are very excited to develop it further. We have a rather long list of novel features that we plan to introduce with the coming updates. But this is also the best time for us to learn from you, our early adopters! What would you like us to add, take away, or improve? We are eager to learn about the way you are using FuncDoodle and how you think we can make it even more useful and fun. Here are some of the specific questions that keep us awake at night:

• In what additional ways would you like to export your doodles? Export animated GIFs? Export to social networking sites or great graphing calculator apps like Desmos? Export to online t-shirt printing services (doodle on one side, functions on the other)?

• What additional shapes would you like FuncDoodle to learn? Spirals, hearts, flowers (in polar coordinates)? Solid shapes (as inequalities)?

• Would you be interested in sharing your doodles with a community of FuncDoodlers on our website? Should this be our first priority?

• What ages find FuncDoodle especially rewarding? (Our early testers ranged from 5 to 42!)

Have fun and keep in touch!

What's New

Version 1.2

Fixed the bug that caused FuncDoodle not to fill the entire screen on iOS 8. Sorry for not catching this sooner. We were deeply immersed in the development of a massive new version, which is coming soon!

A wonderful app with an enjoyable interface. It's a direct and intuitive approach to learning functions, with the added bonus of being a joy to play with.
