**SPACE INK+ — English Description** SPACE INK+ is a companion app built exclusively for SPACE INK e-ink phone cases. No Bluetooth, no network pairing — just bring your phone close to the device and "print" your images onto the e-ink screen in one tap. **Core Features** · **NFC One-Tap Casting** Tap the back of your phone against the e-ink device. It automatically detects and connects — no tedious pairing, and your picture transfers in seconds. · **Multiple Image Sources** Pick photos from your album, snap a new shot with your camera, or browse featured artwork on the home page to refresh your e-ink display. · **True-to-Life E-Ink Color** Built-in 4-color, 6-color, and grayscale dithering engines automatically match the best color mode for each e-ink model. What you preview is exactly what gets printed — switch freely between "Original" and "Preview Effect" to confirm the result before casting. · **One-Tap Save & Share** Save any image you like back to your album anytime for re-casting or sharing with friends. · **Store & Artwork Center** The home page is continuously updated with curated patterns and artwork, and the store offers e-ink devices and accessories — your styling options go way beyond the case. **How to Use** 1. Open SPACE INK+ and choose "Album," "Camera," or featured artwork on the home page; 2. Confirm the image on the preview page and switch views to check the effect; 3. Press the back of your phone against the e-ink device and tap "Cast Now"; 4. Wait for the transfer to complete — your image stays displayed on the e-ink screen. **Compatible Devices** Requires a SPACE INK series NFC e-ink phone case or display device. The device must support NFC near-field communication; enable the corresponding permissions on your iPhone. **Privacy** We respect your privacy. The app only communicates with your device via NFC when you actively initiate a cast, and only accesses your album and camera with your authorization. Your image data is never uploaded or shared. --- Turn every e-ink screen into your personal canvas — SPACE INK+ lets an always-on display tell your story.
