A changing piece of paper
for the moments you keep.
Peanup is a portrait six-color e-paper display for photos and everyday information. Update it from your phone, and the image stays quietly in view.
Crowdfunding preview · final production details may evolve
Physical pigment,
not emitted light.
The manufacturer specifies a 3.68-inch E6 six-color panel. It has 528 × 792 pixels and works out to about 258.7 PPI across its active area.
Six physical e-paper colors reproduce photographs with a distinct printed character. The reflective panel uses ambient light and keeps the frame after the update ends.
The white body feels like a small instant print, not a miniature tablet. Pick it up, place it or carry it with you. A 3 mm profile, 28 g weight and no exposed connector are Kickstarter targets.

Open to more ways to send.
Capture, preview, send
Take a photo, check the six-color preview and send it in the Peanup app. Saved frames stay on your phone.
Repeat without repeating yourself
Use Siri, widgets and personal automations to prepare familiar frames with fewer steps.
Send from Android
Choose and send an image through the WeChat Mini Program. A native Android app is not planned for the first release.
Shortcuts can schedule calendars, weather and reading notes. Future content sources will depend on platform permissions and service support.
The image stays.
Power is spent on change.
One month or more
This is the crowdfunding target, not a fixed runtime promise. Actual battery life depends most of all on refresh frequency and operating conditions.
Place it to charge
Qi wireless charging supports the no-exposed-connector body and keeps everyday charging uncomplicated.
Fridge, desk, phone accessory
The integrated ring supports magnetic placement and compatible MagSafe accessories. It does not imply Apple certification.
Your photograph can stay
on your devices.
Photos are prepared on your phone, then sent over Bluetooth. Cropping and six-color conversion stay local.
Core capture, import, preview, gallery and nearby transfer do not require a Peanup cloud account. Photos and device binding stay local.
Weather and reading cards may contact their source services for content. Your photos are not uploaded for cloud conversion.
Access card,
where supported.
Peanup may work as an access card where the reader supports CUID. Enrollment needs the system owner’s approval and must follow local rules. Unsupported systems will not work.

Before you ask.
01Does the screen stay on all the time?
No backlight is needed. E-paper keeps the image after each refresh. Bluetooth then returns to standby.
02What is the confirmed display specification?
The manufacturer specifies a 3.68-inch E6 six-color panel at 528 × 792 pixels. Its 51.84 × 77.76 mm active area works out to about 258.7 PPI. The website preview only simulates the look.
03Do my photos need to be uploaded?
No. Cropping and six-color conversion happen on iPhone or iPad. Bluetooth sends only the finished frame, and core features do not need a Peanup cloud account.
04Can it update automatically?
Apple Shortcuts can prepare automated updates. Actual timing still depends on iOS and the rules of each content service.
05Is there an Android app?
A native Android app is not planned for the first release. Android devices can send images through the WeChat Mini Program.
06Is the magnetic ring MagSafe certified?
Peanup does not claim that certification. Its magnetic ring works with compatible MagSafe accessories.
07Can CUID NFC replace my access card?
Only where the access system supports CUID. Enrollment needs the operator’s approval and must follow local rules.
08Does a refresh happen instantly like a phone screen?
No. E-paper is not a video display. A visible refresh takes place before the new frame is held. Final refresh timing and visual behavior will be published after production-hardware validation.
09What if my phone cannot find Peanup?
Check that Peanup has power, Bluetooth is enabled and the device is close to your phone. If another phone is connected, disconnect it before scanning again in the app.
10Are the final dimensions guaranteed?
The 3.68-inch E6 panel and 528 × 792 pixel matrix come from the manufacturer specification. The 3 mm profile, 28 g weight and one-month-plus battery life are Kickstarter targets. Battery life depends on refresh frequency.
