10 Tech How-To

Pair Non-Apple Smartwatch with iPhone: Step-by-Step

Guide 10-12486 · Updated · Step by step

This guide walks you through pairing and using a non-Apple smartwatch (like those from Samsung, Garmin, Fitbit, or Amazfit) with your iPhone. You’ll learn the general steps, common pitfalls, and how to fix connection issues. Most smartwatches use a companion app from the manufacturer, which handles the Bluetooth pairing and data sync.

What You’ll Need

  • Your iPhone (with Bluetooth enabled and iOS updated to a recent version)
  • The non-Apple smartwatch, fully charged
  • The companion app for your watch (e.g., Galaxy Wearable, Garmin Connect, Fitbit, Zepp) – download it from the App Store before starting
  • A stable Wi-Fi or cellular connection for initial setup and app downloads
  • Your Apple ID password (for app downloads) and, if required, an account with the watch manufacturer

Step-by-Step

  1. Charge your watch. Ensure the watch has at least 50% battery to avoid interruptions during setup. Follow the manufacturer’s charging instructions.
  2. Enable Bluetooth on your iPhone. Go to Settings > Bluetooth and toggle it on. Keep this screen open – you’ll see the watch appear here later, but you won’t pair from this screen.
  3. Install the companion app. Open the App Store, search for the app that matches your watch brand (e.g., “Galaxy Wearable� for Samsung, “Garmin Connect� for Garmin, “Fitbit� for Fitbit, “Zepp� for Amazfit), and download it. Use the exact app name from the watch’s manual or box.
  4. Open the app and create an account (if needed). Launch the app and follow the on-screen prompts to sign in or create a new account. Many watches require an account to sync data and enable features like activity tracking.
  5. Put your watch in pairing mode. On your watch, navigate to its settings or the Bluetooth/pairing option (often found in Settings > Bluetooth or a dedicated “Pair� icon). The watch will start scanning for nearby devices. If unsure, check the quick-start guide that came with the watch.
  6. Start pairing from the app. In the companion app, tap the option to add a new device (usually a “+� icon or “Add Device�). The app will search for your watch. When the watch name appears, tap it.
  7. Confirm the pairing code. A code will appear on both your iPhone and the watch. Verify that the numbers match, then tap “Pair� or “OK� on both devices. This confirms the Bluetooth connection.
  8. Follow the on-screen setup. The app will guide you through permissions (like notifications, location, and health data). Grant the permissions you’re comfortable with – these allow the watch to sync calls, messages, and health metrics.
  9. Wait for the sync to complete. After pairing, the app may take a few minutes to sync your watch’s firmware and data. Keep the app open and your iPhone near the watch.
  10. Test the connection. Once setup finishes, check that your watch shows the correct time and that notifications from your iPhone appear on the watch (send yourself a test text). If not, check the app’s notification settings.

Common Mistakes

  • Pairing from the iPhone’s Bluetooth settings. You must pair through the companion app, not the iPhone’s Bluetooth menu. Pairing directly from Settings will not work correctly and may cause connection issues.
  • Using the wrong app. Some brands have multiple apps (e.g., Samsung has “Galaxy Wearable� and “Samsung Health�; Fitbit has “Fitbit� and “Fitbit Coach�). Use the one specified in the watch’s manual.
  • Forgetting to allow notifications. After pairing, you must enable notification access in the app. If you skip this, your watch won’t receive calls or messages.
  • Ignoring firmware updates. Many watches require a firmware update during setup. Skipping it can lead to bugs and poor battery life.
  • Leaving Bluetooth off. If Bluetooth is disabled on your iPhone, the watch will disconnect. Keep it on for continuous syncing.

Tips

  • Keep the app updated. Regularly update the companion app from the App Store to ensure compatibility with iOS updates.
  • Manage battery life. Turn off features you don’t use (like always-on display or continuous heart rate) to extend battery life.
  • Customize notifications. In the app, you can choose which apps send notifications to your watch. This reduces distractions and saves battery.
  • Use Do Not Disturb sync. If your watch supports it, enable “Do Not Disturb� sync so that silencing your iPhone also silences the watch.
  • Check compatibility. Before buying a watch, verify that it supports iOS. Some features (like replying to messages) may be limited on iPhone compared to Android.

Troubleshooting

  • Watch not appearing in the app. Make sure the watch is in pairing mode and close to your iPhone (within a few feet). Restart both devices and try again.
  • Pairing fails or times out. Forget the watch from the iPhone’s Bluetooth settings (if it appears there), then restart both devices and retry the app pairing process.
  • Notifications not working. Check the app’s notification settings and ensure “Notifications� are enabled for the app in iPhone Settings > Notifications. Also, verify that the watch’s notification feature is turned on.
  • Watch disconnects frequently. Ensure Bluetooth is on, the watch is charged, and you’re not in an area with heavy interference. Reboot the watch and iPhone, then re-pair if needed.
  • App crashes during setup. Update the app to the latest version, restart your iPhone, and try again. If the problem persists, uninstall and reinstall the app.
  • Data not syncing. Open the app and pull down to refresh, or force-close and reopen it. Check that the watch is connected via Bluetooth and that the app has background refresh enabled in iPhone settings.

Frequently Asked Questions

  1. Can I use any Android smartwatch with an iPhone? Most major brands (Samsung, Garmin, Fitbit, Amazfit) offer iOS companion apps, but some features may be limited. Check the manufacturer’s website for iOS compatibility before purchasing.
  2. Will I be able to reply to messages from the watch? On iPhone, reply options are limited. You may be able to send quick replies or voice responses, but full keyboard input is often unavailable due to iOS restrictions.
  3. Do I need to keep the companion app open? No, but the app must be running in the background for syncing. Enable background app refresh for the app in iPhone settings to ensure data updates.
  4. Can I make calls with a non-Apple watch? Yes, if the watch has a speaker and microphone. Calls are routed through your iPhone via Bluetooth, so the phone must be nearby (unless the watch has cellular).
  5. Why doesn’t my watch show up in the iPhone’s Bluetooth list? That’s normal. The watch pairs through the companion app, not the iPhone’s Bluetooth settings. The watch may appear temporarily, but you should ignore it and use the app.
  6. Will my health data sync to Apple Health? Many companion apps can write data (like steps and heart rate) to Apple Health. Enable this in the app’s settings, under “Health� or “Data Sharing.�
