How to sync Ultrahuman Ring with Apple Health

Yes. The Ultrahuman iPhone app writes Ring AIR / Ring PRO data to Apple Health once you allow it in the Health app. Ultrahuman names workouts, sleep, menstrual data, HRV, skin temperature, energy expenditure, and logged caffeine and water; M1 users also get glucose.

Key caveats: Ultrahuman's own scores (Sleep Index, Movement Index, Recovery) stay in the app, its HRV (RMSSD) won't match Apple's SDNN, and ring steps can double-count with an Apple Watch unless you set source priority.

How to connect Ultrahuman Ring to Apple Health

4 steps on your iPhone, about two minutes.

Before you start

iPhone with the latest Ultrahuman app (iOS 16 or later)
Ultrahuman Ring AIR or Ring PRO paired to the app (M1 CGM for glucose)
Ultrahuman allowed to write categories in Apple Health

Update the Ultrahuman app
App Store → Ultrahuman → Update. Make sure the ring is paired and has synced at least once.
Allow the permission prompt
When the Ultrahuman app asks for Apple Health access, tap Turn On All (or pick categories) and then Allow.
3
Or turn it on from the Health app
Health app → profile picture (top right) → Privacy: Apps → Ultrahuman → Turn On All (Ultrahuman's own instructions).

Give it time
Wear the ring overnight and open the Ultrahuman app in the morning so the night's data uploads. HRV-based guidance needs about 3 days of baseline.

Menu names checked against Ultrahuman Ring’s help pages on October 27, 2026. Apps change; if a menu looks different, see the sources below.

After setup

The ring sends data to the Ultrahuman app over Bluetooth, and the app writes it to Apple Health afterwards. Sleep shows up the morning after a night's wear. Opening the app forces a sync, so keep Background App Refresh on for Ultrahuman. The integration only writes: Ultrahuman doesn't read steps from other devices out of Apple Health. Workouts from other apps come in through Ultrahuman's own Connect Other Apps menu instead.

Avoid double-counting

If you also wear an Apple Watch, steps and active energy can be counted twice. Health app → Browse → Activity → Steps (repeat for Active Energy) → Data Sources & Access → Edit → drag the device you trust most (usually Apple Watch for steps) to the top → Done. Priority only removes overlap for numeric data like steps and energy. Workouts are separate records, so if the watch and the ring log the same session, turn off Workouts for one of them: Health app → profile → Privacy: Apps → Ultrahuman (or the other app) → Workouts off.

Open the Health app and tap Browse.
Choose a category and a data type, for example Activity → Steps.
Scroll down and tap Data Sources & Access.
Tap Edit, then touch and hold the handle next to your device’s app and drag it to the top.
Tap Done. Repeat for other data types you track with more than one device, such as Active Energy or Walking + Running Distance.

The source at the top wins when several write the same data type. New apps and devices are added at the top automatically. Apple Support ↗

Ultrahuman Ring not syncing to Apple Health?

Ultrahuman data stopped appearing in Apple Health

Open the Ultrahuman app and let the ring sync, then check Health app → profile → Privacy: Apps → Ultrahuman and make sure the categories are on. Turn on Background App Refresh for Ultrahuman. Toggling the permissions off and on again often restarts the sync.

HRV in Apple Health doesn't match the Ultrahuman app

That's expected. Ultrahuman shows RMSSD and Apple Health stores SDNN. Compare each number only with its own history.

Steps are doubled or don't match Apple Watch

Set source priority for Steps in Health (Browse → Activity → Steps → Data Sources & Access → Edit) or turn off Steps for Ultrahuman in Health.

Sleep Index, Recovery or Movement scores are missing in Health

That's expected. These are Ultrahuman's own scores and Apple Health has no data types for them. Only the raw data (sleep, HRV, temperature and so on) is shared.

Workouts don't upload to Apple Health

Update to the latest app version (4.3.1 fixed workout uploads), make sure Workouts is allowed for Ultrahuman in Health, and open the app after the session so it can sync. If it still fails, contact support@ultrahuman.com.

Ring won't sync with the app

Put the ring on its charger, turn Bluetooth off and on, force-close and reopen the Ultrahuman app (Ultrahuman's own pairing advice).

Ultrahuman Ring and Apple Health: questions

Does Ultrahuman Ring sync with Apple Health?

Yes. Ultrahuman has a native integration that writes workouts, sleep, menstrual data, HRV, temperature, energy expenditure and logged caffeine/water to Apple Health.

Does Ultrahuman send HRV to Apple Health?

Yes, but the value differs from the app: Ultrahuman shows RMSSD and Apple Health uses SDNN.

Does Ultrahuman read data from Apple Health?

Not for steps or health metrics: the Apple Health link writes data out. You connect other workout sources through Ultrahuman's Connect Other Apps menu.

Can I use Ultrahuman and Apple Watch together?

Yes. Let Apple Watch be the top source for steps and energy in Health, and use the ring mainly for sleep, HRV and temperature.

Do Ultrahuman sleep stages show in Apple Health?

Sleep data syncs, and third-party guides report stages (awake, REM, core, deep). Ultrahuman's Sleep Index score doesn't sync.
