Oura Ring 5 hub notes
- Smallest current Oura: 6.09 mm wide, 2.28 mm thick, 40% less volume than Ring 4 (Oura).
- Typically 6–9 days and ~80 minute charge despite the smaller shell.
- Same membership feature list as Ring 4 (sleep, 24/7 HR, Stress, Heart Health, Women's Health, SpO2). Health Radar / Counsel Health / GLP-1 Insights are described as Gen3-and-newer software, not Ring-5-only scores.
Ring 5 is the smallest current Oura: 6.09 × 2.28 mm titanium, sizes 6–13, typically 6–9 days, same membership software family as Ring 4. Buy it if you fit 6–13 and will pay membership. Skip it if you need sizes 4–5 or 14–15 (still a Ring 4 run) or you refuse a subscription.
Samsung Galaxy Ring hub notes
- Energy Score in Samsung Health from sleep, activity, and heart-rate data (US support).
- Galaxy phone lock-in is the product, not a footnote — data in Samsung Cloud.
- 10 ATM + IP68; US support width 7 mm, thickness 2.6 mm, 2.3–3.2 g.
Galaxy Ring is the Samsung Health night-sleep ring: $399.99, titanium, sizes 5–15, up to 7 days (size-banded), Energy Score, auto walk/run. It needs a Galaxy phone + Samsung account. Buy it if you already live in that stack. Skip it if you use iPhone, want a no-Galaxy Android, or need Oura-style cross-platform membership insights.
