Inkalot (formally Doodle-A-Lot) is a minimalistic, just enough, drawing app, made with an Apple Pencil in mind. It's easy to use and a lot of fun. You can export to the Files App, Photos App or Air Print. Exports are 8.5 x 11 @ 300 dpi (600 dpi option for newer iPads) in PNG format with transparency and 1-bit options. The ink is smooth, but like the real thing, it picks up that organic irregularity that exists with pen and paper. Record your drawing sessions for quick videos. Get out of your left brain and enjoy the simplicity!
