If they do but are missing from Apple Health, Health Connect, Google Health, or Samsung Health, troubleshoot that separate sharing connection rather than resetting the ring.
Understand the two links in the sync path
A smart ring usually sends data to its maker’s app first. That app may then share some of the data with a separate health platform. Treat these as two connections to check independently:

- Ring to companion app: Tests whether the ring can communicate with the phone and whether its app has received recent measurements.
- Companion app to health platform: Tests whether the app is authorized and configured to share data with Apple Health, Health Connect, Google Health, or Samsung Health.
If the latest measurements are in the companion app, the first connection is working even if another health app is empty. A health platform may receive only selected categories, not every metric the ring records.
Start with the basic connection checks
- Charge the ring. If its battery is low, charge it using the charger specified for your ring model.
- Bring the phone close to the ring. Keep them near each other while checking or reconnecting.
- Turn on Bluetooth. Check the phone’s Bluetooth setting; also confirm that the companion app has any Bluetooth or nearby-device permission the phone requests.
- Open the ring maker’s app. Check its device page for a connection status and look for the newest measurements. Give the app time to connect and sync.
- Check for app and phone updates. Install updates recommended by the ring maker, then try syncing again.
These checks follow Oura’s official connection guidance, which also recommends charging the ring, keeping the phone beside it during reconnection, and using current app and phone software. Exact settings and procedures vary by ring, phone maker, and operating-system version.

If the ring app still is not receiving data
Review phone permissions and background restrictions
In phone Settings, find the companion app and check its permissions, including Bluetooth or nearby devices where applicable. On Android, also inspect its battery-use and background-data settings if syncing works only while the app is open or stops when the phone is idle. Search Settings for the app’s name, permissions, and battery use rather than relying on a fixed menu path: Android labels and available controls vary by version and phone manufacturer. Oura notes that Android-version and device-manufacturer differences can affect Bluetooth connectivity.
Reset pairing only after the basic checks
Bluetooth reset steps are specific to each ring. For Oura, its documented procedure is to leave the ring on its powered charger, switch the phone’s Bluetooth off, force-close the Oura app, switch Bluetooth back on, remove the ring from the phone’s Bluetooth device list, and then open Oura and pair again through the app. Do not apply that sequence to a different brand unless its maker recommends it.
If Oura still does not reconnect, its support guidance lists more involved options such as restarting the phone, reinstalling the app, or using its documented hardware reset. Start with the maker’s instructions: a reset can affect device setup, and unsynced measurements may be at risk.

If the companion app has data but a health platform does not
Check the integration separately in the companion app and the destination health platform. Confirm that sharing is enabled and that permission is granted for the data categories you want. Then check whether the missing measurement type is one the ring app actually shares.
Google’s Health Help Center says its Google Health app does not connect directly to Oura: Oura data must pass through the Oura app and a supported health integration. Google describes third-party connections as generally flowing through Health Connect on Android or Apple Health on iPhone. Samsung’s developer guidance says Samsung Health can synchronize selected categories, including activity, heart rate, and sleep, with Health Connect after the required data permissions are granted. These routes and available categories are not universal across rings or apps.
If Samsung Health is the source or destination, Samsung’s troubleshooting guidance also recommends checking app versions and using “Sync now.” The exact availability and location of that control may depend on the current app version.

Before moving the ring to a new phone
Follow the ring maker’s transfer instructions rather than trying to pair the ring to the new phone first. For Oura, the published process calls for a stable internet connection and signing out so app data can be backed up, followed by removing the ring from the old phone’s Bluetooth list. Oura warns that measurements stored on the ring since its last sync are erased during transfer; previously synced historical data remains available. This warning is specific to Oura, so check another maker’s instructions before transferring a different ring.
