DynaDraw is a dynamic drawing application based upon a program written in 1989 by Paul Haeberli. The program can be used to make a variety of drawing effects, but it is especially useful for calligraphy. The drawing works like a spring and mass system, as if your finger were pulling a weighted paintbrush attached to it with a spring. You can adjust the spring, mass and drag parameters to change the dynamic effect.

Great Calligraphy Practice App

The best practice board to work on my calligraphy. It's also a fun app to just doodle on while waiting in line or waiting for an appointment. Very fun for all ages. It's easy to adjust how you want your ink line to perform. Best app available for practicing your letters and numbers.

It's awesomely simple. Keep downloading it out over the years because no other apps do what this one does so well

Brought Back a Classic

I was excited to hear that DynaDraw has been brought to the iPad, and I was not disappointed. This update of the physics-based calligraphic drawing method works even better on a touch platform than it did using a mouse. The interface is lean and stays out of your way as you create your works of art. Also, you cannot argue with the price. Beautiful program, very enjoyable to use.
