LogCase turns the back of your iPhone into a page of electronic paper (E-Paper). Choose an image and tap Cast. A few seconds later, it is on the back of your phone, and it stays there with no power and no glow, the way ink stays on paper. Leave it for a year, or change it before you leave the house. WHAT YOU CAN DO - Cast any photo from your library. Crop and adjust it, and see exactly how it will render on the panel before you send it. - Draw from the built-in gallery. A curated collection of artwork, including public domain works from museum holdings, organised so there is always something worth putting on. - Make something with Apple Intelligence. Describe the picture you want, and Image Playground creates it on your iPhone, already shaped and coloured to match your case. Requires a device that supports Apple Intelligence. - Keep your favourites private. Saved images stay on your iPhone rather than on our servers, and you can back them up to your own iCloud if you would like a copy elsewhere. - No battery and no charging. The display draws what it needs through the case for a few seconds while it redraws, then needs nothing at all. LogCase requires a LogCase e-paper phone case, available from brachistalog.com.
