Can the sleeve ring a phone that is set to silent or Do Not Disturb?

Yes. Double-tap Pad 5 sends an explicit Bluetooth command that your paired phone handles as a critical find-my-device ring, which sounds at max volume even when the ringer is muted; double-tap Pad 4 first to arm the loud override as a second safeguard.

What does the smart-lock trigger do?

Hold Pad 3 to arm or disarm a BLE proximity lock: when armed, walking away from your paired device locks it, and the 8×32 matrix shows a LOCKED shield—so your sleeve works as a hands-free security switch too.

Do I need an app installed for this to work?

The ring and lock triggers run through the sleeve's standard BLE profile engine, paired via the Sleeve Studio app; device-specific hooks are configured in plain English in the Sleeve Studio app, and nothing has to live on the App Store.

Why Hunting for Your Phone to Ring Your Phone Is the Worst Catch-22

The device you need is missing: You search frantically while the phone you would use to locate it sits silently under a pillow.
The trigger lives on your body: A single double-tap rings the phone, and the sleeve can arm or disarm a smart-lock as the key.
Peer-reviewed textile roots, shipping hardware: The Oct 2026 NUS Nature paper coined “garment GUI” with a lab-only woven pixel fibre (not for sale); our shipping $199 sleeve uses 5 sewn conductive-fabric pads and a removable 8×32 LED pod.
