Quiet on the wrist. Clear in the app.

Belfar Pro pairs a screenless wrist form with optical sensing, motion sensing and Bluetooth LE connectivity. The band gathers supported wellness signals; the G Band app is where those signals become readable trends.

Designed around fewer interruptions

Without a display, the band does not compete for attention with messages, apps or watch-face complications. The interaction model is deliberate: wear first, review later.

Supported signals

The supplied specification lists sleep, heart rate, activity, HRV, blood oxygen and additional wellness features. BELFAR V1 highlights only the clearest general-wellness use cases until product validation and compliance documentation are complete.

Data path

Band → Bluetooth LE 5.3 → G Band app → personal wellness context.

Launch dependency: provide official G Band screenshots, privacy/data handling documentation, validated claims, test reports and final user instructions.
