one shield.
drawn to scale.

A mesh node on the back of your phone, drawn from the same CAD that machines it.

Ceramic powder-coated titanium or anti-microbial pure brass, both rust-proof. Set with the ñü.isheru gemstone, platinum, and a laser-etched pyrite hexagon, the mirror of the Triangulum constellation. CNC’d to add 0 mm to your phone, based on the camera bump.

0 mm: Above the lenses: your iPhone gets no thicker
4.7 mm: On the back, level with the lens tops
7.5 Wh: Its own battery, about 6 hours relaying
600 m: Shield to shield, or 2 km to a rooftop node

suñůlink.shield

your phone becomes part of the network.

A post-quantum mesh transceiver in a battleproof titanium shell, machined to your phone’s own curves. It turns the phone into a node: it carries traffic for the people around you, keeps your messages flowing when Apple’s push service can’t be trusted, and earns while it works.

6 hours: relaying on a full charge, then a sip of your iPhone’s battery
15 min: to 50% over USB-C from a wall charger or power bank, full in about 45
Clear: over the camera, with an opening for every lens, cut out of its view

Fits iPhone X and later · Google Pixel · Samsung Galaxy S and AThe khėnsu.ñü app needs iPhone 11 or later. On older iPhones and on Android, the shield runs as a node. Battery life and charge time vary with use and settings.

side view

zero millimetres. no new bump.

The shield covers the whole back, camera included, and stops level with the lens tops, so it adds nothing above the camera. Every lens, the flash and the sensors get their own opening, cut so none of them ever sees it, even the ultra wide at 120°. Inside that depth: a 7.5 Wh battery, about six hours of relaying on its own cells.

Each shield is CNC-machined from titanium for a precise fit, following the iPhone 18 Pro’s own edge curve, so the shield picks up where the phone’s edge leaves off. No step, no lip, one seamless shape.

your colour. or solid brass.

Ceramic powder-coated titanium in every iPhone 18 Pro and Pro Max finish, so it looks like part of the phone and doesn’t show fingerprints. Grade 5 titanium is about 1.6 times as strong as the aluminium iPhone 18 Pro is made of, and a shock-absorbing layer underneath takes the sting out of drops. Or bare brass, a copper alloy that kills bacteria on its surface and never rusts. Either way it sits level with the lens tops, adding nothing above the camera, with the lenses, the flash and the sensors clear in its opening.

Renders from the CAD model, on iPhone 18 Pro geometry measured from Apple’s published model. Brass is heavier than titanium (about 136 g against 95 g) and ages to a warm patina shaped by your hands, how you carry it and the air it lives in, so no two brass sunulink.shields end up alike. It is left uncoated, since a coating would stop it working on germs. Brass still needs regular cleaning, like any surface. iPhone is a trademark of Apple Inc., registered in the U.S. and other countries; finish names are Apple’s.

One model for iPhone 18 Pro and Pro Max, and for iPhone 18 on its release, in your iPhone’s colour, matte titanium or solid brass. Figures for iPhone 18 Pro. Battery life at about 1 W of relaying; charge times with a 20 W or larger USB-C PD charger. Battery life and charge time vary with use and settings. From your iPhone it takes at most 1 W, roughly 5–8% of the iPhone’s battery an hour. It clears every lens, flash and sensor, and every camera’s field of view.
