The Ultrahuman ring reaches Beacon through Apple Health, and Beacon recognises it as the recorder.
Where a ring is strong, and where it isn't
A ring is well placed for sleep, resting heart rate and heart-rate variability — it is on you all night, which a watch often isn't.
Outdoor distance is the opposite case. A ring has no GPS, so it estimates distance from cadence. If you also carried a phone or wore a watch that recorded an actual GPS track, Beacon uses the GPS measurement for that session, and treats the ring's figure as the inference it is.
That rule is about measurement capability, not about which brand Beacon prefers. It holds even when the GPS track is the shorter of the two — a GPS source that stopped early still measured what it covered, while a step estimate never measured anything.
How it reaches Beacon
Beacon has no direct connection to this device. Its data arrives through Apple Health: the vendor's own app writes to Health, and Beacon reads from there. So what Beacon can see is whatever that app chooses to write — Beacon can't ask for more than the vendor shares.
Two things follow:
- Set up the vendor's app first, and allow it to write to Apple Health. Beacon reads whatever lands.
- Your full history imports. Apple Health is the one connection Beacon reads all the way back, not just the last 90 days.
Attribution
Beacon recognises this device by name, so its readings are credited to it rather than to Apple Health generically. That matters when you wear more than one thing: two sources reporting the same night or the same run are kept apart instead of being averaged into a number that describes neither.
