[Plano, TX — 24 March 2026] — Ultrahuman today opened U.S. pre-orders for Ring PRO following clearance from U.S. Customs and Border Protection, bringing subscription-free health insights back to American buyers.
With up to 15 days of battery life expanded to 45+ days via the new PRO Charging Case1, Ring PRO delivers uninterrupted health insights. With a host of new medical-grade health intelligence features and all-new PowerPlugs, Ultrahuman returns to the U.S. stronger than ever.
A feat of engineering
In addition to category-defining battery life, Ring PRO’s titanium unibody architecture houses a redesigned heart-rate sensing system and a dual-core processor that enables more accurate insights via on-chip machine learning.
With 250 days² of on-device health data storage, Ring PRO frees users from constant phone tethering. It also features ProRelease Technology, which allows the ring to be safely cut apart in the event of finger swelling or injury.
Ring PRO is available in Bionic Gold, Space Silver, Aster Black, and Raw Titanium, in sizes 5–14.
CEO Mohit Kumar said: "Ring PRO is a breakthrough in wearable technology – delivering category-defining battery life within the demanding constraints of a smart ring. We’re delighted to be back in the U.S., and engineering has prevailed – as it always does."
Built for longevity: PRO Charging Case
The PRO Charging Case is more than a charger – it's an extension of the Ring PRO experience.
Offering up to 45 days of combined battery life and up to one year of on-device data storage2, the PRO Charging Case unlocks uninterrupted tracking performance.
Both Charger Mini and the PRO Charging Case feature UltraSnap Charging Technology – an energy-efficient mechanism where Ring PRO magnetically clicks into place, generating less heat than conventional wireless charging. This protects Ring PRO's long-term battery health. Other features include:
No mandatory subscription. No paywall. No compromise.
Unlike its main competitors, Ultrahuman does not charge ongoing fees for core health insights. Sleep, recovery, movement, stress, and circadian data are all accessible without a subscription — and users retain full ownership of their health data.
For those who want more, an expanding suite of optional PowerPlugs — developed with specialist partners — unlocks medical-grade capabilities including:
