There's a wide range of e-ink tablets and displays available. Many of the tablets run Android and are largely the same as any other Android device. The displays can be used with any OS, obviously. There are also e-ink phones (smart and otherwise), watches, and other devices. For text and graphics, you'd generally want to use a higher-quality, lower-refresh-rate mode. Which is to say that there's quite a bit of established UI/UX knowledge that wants a refresh. I've distilled a set of basic principles: persistence is free, pixels are cheap, paints are slow, colour is (mostly) nonexistent, and the more ambient light the better. Paginated-navigation (whole screen changes in one go), line-art, and dithered or halftoned images work relatively well, raster images not quite so much, though can be acceptable. <https://diaspora.glasswings.com/posts/638a8d10e041013afba8448a5b29e257 https://diaspora.glasswings.com/posts/638a8d10e041013afba844...> For a demonstration of a wide range of displays (the best ones are featured last) as of 2021, see: <https://yewtu.be/watch?v=KdrMjnYAap4 https://yewtu.be/watch?v=KdrMjnYAap4>
