Z3RO: E-Ink Photo Magnet

A photo you can hold — one that never needs charging. Z3RO is the app for the Z3RO E-Ink Photo Magnet, a battery-free color e-ink card that updates over NFC. Choose a photo, make it yours, then hold the card to your iPhone. The picture moves across in a single hold, and then it stays — no battery, no power — until you choose a new one. MADE FOR E-INK Color e-ink isn't a phone screen, and the editor is built for the difference. Crop and frame, tune contrast and color for the panel, add text, stickers and backgrounds, or lift your subject off its background. The true preview shows exactly how the card's 4-color display will render your photo. What you see is what the card holds. RELICS — PHOTOS MEANT TO BE GIVEN Seal a photo with a caption as a Relic and give it to someone nearby, straight from your iPhone to theirs — no internet involved. Decide how many times they can flash it, or leave it unlimited. Lock it to the first card it touches, so it can only ever be flashed there. Make it a Secret Relic, and the only way to see the photo is to flash it onto an e-ink card. EVERY CARD, NAMED The fridge, the desk — give each card a name and always know which is which. PRIVATE BY DESIGN No account. No sign-up. No cloud. Your photos stay on your iPhone and your cards. Designed in Hong Kong. In English and Traditional Chinese. Requires the Z3RO E-Ink Photo Magnet. Designed for Apple iPhone 13 – 18, with iOS 17 or later.
