Light screenless ring, ~5-day battery
An explicitly subscription-free smart ring with the most data-ownership-friendly posture of the rings — undercut for US patients by a patent ruling that has banned its import and sale since October 2025.
What it measures
Sleep stages, HRV, resting and continuous HR, skin-temperature variation, activity, plus app scores (Dynamic Recovery, Movement Index, Stress Rhythm, Circadian/Sleep Index). No ECG or medical BP.
Regulatory status
Not a medical device; no FDA clearance for the ring. 'Uses FDA-approved sensors' is marketing, not a clearance. A 2026 Migraine module integrates a partner's FDA-cleared therapeutic — that clearance is not the ring's.
Validation & accuracy
Less peer-reviewed validation than Oura or Withings; accuracy claims rest largely on internal/marketing data. Reviews find tracking competitive but the app weaker.
Data control & export
Best-in-class stated posture: CSV and XML export directly from the app, marketed as a one-time purchase with lifelong access to the ring and your data.
Wearability & battery
A light titanium smart ring, comfortable and screenless, ~4–6 day battery. Easy to wear, but limited day-to-day breadth beyond tracking.
Cost & access
One-time ~$349, no mandatory subscription for core metrics; some optional modules may carry fees.
Who it serves
Built for data-autonomy-minded users — but a US ITC ruling for Oura (2025) found infringement and triggered a US import/sales ban effective Oct 2025.
Who is left out or burdened
US patients largely cannot legally obtain it; thin independent validation; no cleared clinical output.
✓ Strengths
- No mandatory subscription for core metrics
- Open CSV/XML export; lifelong data access claim
- Comfortable, lightweight titanium ring
✕ Weaknesses
- US import/sales ban in effect since Oct 2025
- Wellness-only with the thinnest validation of the rings
- No broad public developer API
- App experience weaker than Oura
32
Why this clinical score. Wellness-only with the least validation of the rings — the lowest clinical score in the directory.
52
Why this empowerment score. The no-subscription, open-export model is the most empowering on paper, but the US import ban sharply limits whether US patients can actually exercise that control.
62
Why this everyday score. Comfortable, screenless, and low-maintenance like other rings, with a slightly shorter battery and a weaker app — and US availability is in question.

Reviewers like the no-subscription pricing, fast metabolic/glucose-adjacent features and a sleek app aimed at biohackers. Criticisms center on sleep-tracking accuracy that can lag Oura and a younger data ecosystem.
