Exact apps, compatibility, and menu names depend on the watch brand, model, and software generation. If a screen or step differs from this guide, use the manufacturer’s instructions for your specific model.
Before you start
- Identify the watch model and check that it is compatible with your phone.
- Charge the watch and phone.
- Turn on Bluetooth on the phone.
- For Apple Watch, update the iPhone and connect it to Wi-Fi or a mobile network.
- Install or open the official companion app for the watch.
Compatibility is not universal: Apple Watch requires a compatible iPhone, and newer Wear OS Galaxy Watch models cannot be set up with iOS. Requirements vary by model and software generation.
How to pair a smartwatch with your phone
- Open the companion app. Use the Apple Watch app for Apple Watch, the appropriate Wear OS or manufacturer app for supported Wear OS watches, or Garmin Connect for Garmin watches. Do not begin by pairing from the phone’s Bluetooth settings.
- Turn on the watch and start setup. Follow any language or terms screens, then choose the setup or add-device option in the app.
- Select the watch and keep it nearby. Choose the watch when it appears in the app and keep the phone and watch close while setup continues.
- Confirm the pairing. Apple Watch uses an animation that you scan with the iPhone camera, with manual pairing available as a fallback. Wear OS displays a code on both devices; confirm only when the codes match.
- Complete the prompts. Depending on the platform, you may sign in, choose a new setup or restore, select wrist orientation, grant permissions, or install an update.
- Check the connection. Confirm that the companion app reports the watch as connected, then test basic syncing or notifications.
Garmin recommends pairing through Garmin Connect for reliable syncing and notifications. Google’s instructions say that Wear OS steps can vary by manufacturer and software version.

Pairing routes by watch family
| Watch family | Setup route | Important compatibility note |
|---|---|---|
| Apple Watch | Use the Apple Watch app on a compatible iPhone. Scan the watch animation or choose manual pairing. | Requires a compatible iPhone. Check Apple’s instructions for your model. |
| Wear OS | Use the compatible Wear OS or manufacturer companion app and confirm matching pairing codes. | Google says Wear OS 3 watches are not compatible with the legacy Wear OS app. Some manufacturers use their own app. |
| Samsung Galaxy Watch | Use Galaxy Wearable for supported models. | Newer Wear OS generations, including Galaxy Watch4 and later, require a compatible phone for initial setup and are not iOS-compatible. Some older models support iPhone. Requirements vary by model and region. |
| Garmin | Put the watch in pairing mode and complete setup through Garmin Connect. | Garmin recommends using Garmin Connect rather than pairing first through the phone’s Bluetooth settings. |
Moving a watch to a new phone
Check the manufacturer’s transfer and backup instructions before disconnecting or resetting the watch. Google says a Wear OS watch can connect to only one phone at a time, so switching phones may require disconnecting it from the current phone. A factory reset erases apps, settings, and data.
Troubleshooting pairing problems
The watch does not appear in the app
- Confirm that the watch and phone are charged, Bluetooth is on, and the devices are compatible.
- Keep the devices close and restart the pairing flow from the official companion app.
- If the watch was paired to another phone, disconnect it using that phone where possible before switching.
The Apple Watch camera will not scan the animation
Choose Pair Apple Watch Manually in the Apple Watch app and follow the prompts.
