Wear OS apps should work independently of a phone. However, if your Wear OS app
depends on a mobile app, see the following information about connecting either
an emulated watch or a physical watch to a phone.

## Pair devices with a watch emulator

You can pair devices to your watch Android Virtual Device (AVD), or emulator,
manually or with the Wear OS emulator pairing assistant.

### Use the Wear OS emulator pairing assistant

> [!NOTE]
> **Note:** Your phone must run Android 11 (API level 30) or higher and have the Google Play Store installed to use the Wear OS emulator pairing assistant. To upgrade system images for your emulated devices, use the [SDK Manager](https://developer.android.com/studio/intro/update#sdk-manager).

The Wear OS emulator pairing assistant simplifies managing and connecting Wear
emulators. You can pair multiple Wear devices with a single virtual or physical
phone. Android Studio saves and re-pairs previously paired devices when you
launch them.

To pair two devices, follow these steps:

1. If you haven't already, [create a Wear emulator](https://developer.android.com/training/wearables/get-started/creating#emulator).

2. If your phone doesn't have a companion watch app, install it. For example,
   if you don't have the Google Pixel Watch app installed, follow the prompts
   to sign in to the Play Store, install it, and set it up.

3. In the **Device Manager** , click the overflow menu icon next to a device you
   want to pair and select **Pair Wearable**.

4. This action launches the Wear OS emulator pairing assistant. If you selected
   **Pair Wearable** on the entry for a phone, you see a list of available Wear
   devices. If you started with a Wear device, you see a list of available
   phones. Select the device you want to pair and tap **Next**.

5. It might take a few minutes for Android Studio to launch and prepare the
   devices.

After your devices are successfully paired, the **Device Manager** shows small
icons next to the paired devices. You can also tap the overflow drop-down menu
and select **View Details** to see a list of paired devices.

### Connect a phone to multiple Wear OS devices

To connect a second Wear device to a virtual or physical phone, follow the same
steps you would for an initial pairing: locate the phone or Wear device you want
to pair in the **Device Manager** , click the overflow menu icon, and click
**Pair Wearable**.

## Set up a phone

This section describes how to set up a mobile phone with a Wear OS companion
app, such as the Google Pixel Watch app.

### Use the Android version of the companion app

On an Android phone, go to the [Google Pixel Watch app](https://play.google.com/store/apps/details?id=com.google.android.apps.wear.companion) listing.
Tap **Update** to download and install the app. After installation, confirm that
**Auto-update** is selected for the app. See the "How to update individual
Android apps automatically" section of [Update downloaded apps](https://support.google.com/googleplay/answer/113412).
Tap **Open** to start the app.

#### Pair an Android phone to a watch

After you install the companion app on a phone, unpair any outdated watch
pairings, if necessary. Then pair the phone to a newly imaged watch. To do this,
complete the following steps:

1. On the phone, select your watch device name from the list of devices. A
   pairing code displays on the phone and on the watch. Check that the codes
   match.

2. Tap **Pair** to continue the pairing process. When the watch connects to the
   phone, a confirmation message displays. After confirming, a list of accounts
   will appear on the phone.

3. Choose a Google Account to add and sync to your watch.

4. Confirm the screen lock and enter the password to start copying the account
   from the phone to the watch.

5. Follow the instructions in the wizard to finish the pairing process.
