Read full descriptionHide full description
The AI Einkcase is an app designed for intelligent e-ink phone cases (E Ink Phone Case), allowing users to DIY the display content of the e-ink screen on the phone case. With this app, you can edit text and pictures to create your own back-cover wallpaper, or select wallpapers you like from the official theme library for display on the e-ink screen of your phone. When displaying pictures, the color e-ink screen image quality enhancement algorithm is used, making the details and edges clearer and the transitions more natural, resulting in a more perfect display of illustrations and portraits. Detailed features include: 1. Built-in many interesting and practical theme wallpapers, and irregularly update hot-topic pictures; 2. Provide a quick-function for DIY-exclusive back-cover pictures; 3. Personal QR code / schedule display; 4. Multiple filter / special-effect options; 5. Collection of personal pictures and creations.
