Titanium Alloy Smart Ring Size 12

The HTC Helio Smart Ring in size 12 is a titanium alloy wearable designed for continuous health monitoring. It tracks heart rate, blood oxygen, sleep stages and stress levels through an EDA sensor. The device pairs with a smartphone via Bluetooth and requires no subscription for full access to analytics in the Zepp App.

16 MB Storage and Four-Day Operation

Onboard memory of 16 MB stores several days of biometric data between syncs. A full charge takes 1.4 hours and delivers up to four days of operating time. The 1.04-inch AMOLED display shows metrics at a glance, though the ring lacks a touch screen for direct interaction.

Sizing Kit and Water Resistance

Accurate fit is essential because Helio sizing differs from standard jewellery sizes; using the sizing kit before purchase is strongly recommended. Water resistance allows wear during hand washing, rain and sweat-heavy workouts. The package includes the ring, a charging dock and documentation for the Zepp App ecosystem.

Questions about this item

Will the Helio Smart Ring Size 12 pair with a Windows laptop over Bluetooth for data sync?

The ring connects via Bluetooth to a smartphone; Windows OS compatibility is listed, but the primary sync path is through the Zepp App on a phone.

How can I confirm the 1.04" AMOLED display is showing live heart-rate and SpO₂ readings after setup?

Open the Zepp App on your paired phone; the dashboard updates heart rate, blood-oxygen and stress metrics in real time when the ring is worn.

Does the Size 12 titanium alloy ring ship with a charging cradle and the sizing kit, or must I buy them separately?

The box includes the ring and a magnetic charging dock for the 1.4-hour charge; the Helio Ring Sizing Kit is sold separately and recommended before purchase.
