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

Fun little app

Originally tried out of curiosity... The fact that it is based on software from the 80s tickled my retro fancy. The dynamics do a great job smoothing out my handwriting. I wish some of the dedicated notebook apps on iOS made use of this.

Fun to do loose sketches with higher spring, lower weight settings.

The only reason I didn't give it 5 stars is the lack of ink color.. I'm nitpicking though.

Definitely worth grabbing.
