We're 2D Geometry, Inc.

We design and engineer everything ourselves — from the ink that meets your pencil to the way your notes sync — because the feeling of pen on paper deserves software made with the same care.

Our flagship is Pronotes, a notebook for iPad and iPhone, built for people who think best with something in their hand.

We're a small, independent studio, and we like it that way — it lets us obsess over the details that make a notebook feel effortless.
