New affordable titanium smart ring packs haptics, display, and 30-day battery

Smart rings have been steadily gaining ground on wrist-worn wearables. However, most of them have stayed quite minimal — no screen, no alerts, just passive sensing, which — in hindsight — is intentional. Rogbid's new SR15 Ultra takes a different approach instead.

The SR15 Ultra is a titanium smart ring with a built-in display. It lets users check time, step count, heart rate, blood oxygen levels, sleep stats, and battery status directly on the ring without pulling out a phone. It also features a vibration notification system for calls, messages, alarms, and social media alerts. This feature is pretty uncommon in the smart ring category, where most competitors like the Oura Ring 4 (curr. $399 on Amazon) and Samsung Galaxy Ring offer no haptic feedback at all.

Health tracking covers your standard bases: continuous heart rate monitoring, SpO₂, sleep quality, HRV, and stress tracking, all running 24/7. A gesture control system also lets users interact with smartphone apps through hand movements, though real-world accuracy for this kind of feature tends to vary. Weekly fitness reports and multi-sport mode round out the activity side.

On paper, the hardware is decent for the price. The ring is rated 5ATM water resistant, charges fully in two hours, and Rogbid claims up to 30 days of battery life with the included charging case. Bluetooth 5.2 handles connectivity, and it works with Android 9.0 and iOS 10.0 and above. Sizes run from US 8 through 14, with Black, Silver, and Gold finishes available.

The SR15 Ultra is available now at the Rogbid Store for $99.99. The company adds that this is a promotional price tag that also includes a free mini fan while supplies last.
