Ultrahuman Ring + Apple Health: Heart Rate Syncs in the Background

70 BPM does not measure heart rate; it reads what Ultrahuman has already written into Apple Health and lines it up with your calendar. So the useful question for Ultrahuman owners is not “is it compatible” but “what exactly does Ultrahuman send, and how much of the day does it cover?” Everything below comes from Ultrahuman’s own support documentation, linked where quoted.

What Ultrahuman writes to Apple Health

The heart-rate line on Ultrahuman’s official page reads, verbatim: “Native Integration with Apple Health ... data — including Sleep Stages, HRV, Heart Rate — will flow automatically in the background.” (Ultrahuman: How to connect Ultrahuman Ring AIR and Apple Health (30 May 2025)).

The full export list on that page:

• Heart Rate
• HRV
• Sleep Stages

The question that decides everything: does it cover the whole day?

Full-day heart rate: yes. Ultrahuman’s wording is “flows automatically in the background” from a ring worn 24/7. It does not use the phrase “all-day” for the Apple Health write specifically, so we are not going to put it in Ultrahuman’s mouth — but background, automatic heart-rate sync from a continuous wearable is the strongest official statement any ring maker on this site gives. Check the day view in Apple Health after a day of wear to confirm the density for yourself.

How to connect Ultrahuman to Apple Health

Ultrahuman documents the connection from the Apple Health side:

1. Open the Health app on your iPhone.
2. Tap your profile picture (top right).
3. Tap Apps, then Ultrahuman.
4. Tap Turn All Categories On.

Ultrahuman notes that its HRV baseline takes about three days to build after connecting.

Once connected, open 70 BPM, grant it Apple Health read access for heart rate, and the samples Ultrahuman has written appear on the day chart against your calendar events. 70 BPM shows every heart-rate sample in Apple Health, whichever device wrote it — it never filters by brand.

If Ultrahuman data is not showing up

The baseline takes a few days

Ultrahuman states its HRV baseline builds over about three days after connecting. Heart-rate samples themselves should appear sooner.

Enable from the Health app, not the ring app

Unusually, Ultrahuman’s documented route runs through Apple Health’s own Apps list rather than a toggle inside the Ultrahuman app.

How to check what you are actually getting

Open Apple Health › Browse › Heart › Heart Rate and switch to the day view. Readings scattered across an ordinary day mean all-day samples are arriving; readings clustered only into workout blocks mean you are getting session data only. Under the same screen, Data Sources & Access shows which app is writing. This check reflects your actual device, firmware and settings, and beats any compatibility page — including this one.

This article reflects Ultrahuman’s published documentation as read in September 2026. Sync behaviour changes; check the linked support page before relying on it. 70 BPM is not a medical device and does not diagnose anything.
