Lightwell is a powerful creation tool for artists, designers, and developers. Build, prototype and publish your own native iOS app without writing code.
Been experimenting with earlier versions of Lightwell for a while now and love where the team has taken the platform. Its perfect for content creators looking to build and prototype interactive stories, learning modules, graphic novels, lightweight applications and games. You can tell right away it was designed with visual storytelling in mind. If you're an illustrator, animator or motion designer with tale to tell, check it out.
