About Spread Planner

Spread Planner shows your week and your handwritten notes as a two-page spread. The developer points out that the Duo’s inner screen has nearly the proportions of A-series paper: open it and the week is on the left page and notes on the right, like an open A6 planner. Half open, the fold becomes the spine; closed, the cover shows just today’s page. There are no pictures of it on the Duo yet.
