A smart-ring companion app that can call for help.

A SwiftUI companion app for a safety smart ring — driven by a custom-engineered BLE protocol and wired into the Noonlight emergency API so a discreet gesture can summon real help.

The challenge

What needed to be true

A safety wearable is only as good as the moment it's needed. The ring had to pair reliably, stay connected, and trigger a real emergency response — instantly and discreetly.

WearOpal needed a companion app built directly against a custom BLE protocol for the ring, integrated with a real emergency-dispatch service rather than a simulated one.

How we approached it

The approach, step by step.

Engineer the BLE layer

We built a custom BLE SDK and protocol to talk to the ring reliably — pairing, connection stability, and the command path that matters in an emergency.

Wire in real help

Noonlight emergency API integration so a trigger reaches a real dispatch service, not a placeholder.

Build a calm, native UI

SwiftUI for a clean, responsive iOS experience, with Firebase backing the app's data and messaging.

Where it landed

Built by the founder at Clustox, WearOpal pairs a safety smart ring with a SwiftUI app over a custom BLE stack and a real emergency-dispatch integration — turning a gesture into help.
