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.
Ultrahuman Ring PRO hub notes
- Up to 15 days (Turbo ~12 / Chill 15+); case up to 45 days extra.
- Up to 250 days on-ring storage; case up to 1 year of ring data (Chill Mode footnote).
- No recurring fee for core data (US buy FAQ, 2026-09-19).
PRO is the long-battery, no-mandatory-sub Ultrahuman: $479, up to 15 days, 250-day storage, PRO case. In the US it is a pre-order shipping from 10 October 2026 — the February blog excluded the United States. Buy it if you will wait and want continuity. Skip it if you need a ring on a finger this week, or if AIR’s lighter 4–6 day leftover is enough.
