Connect Your Android Watch to iPhone.
Step-by-step setup, plus everything to check before you start. Most people are done in 5 to 10 minutes.
Prerequisites
Check these before you start:
- โiPhone: iOS 17.6 or later (Lynio's own minimum requirement).
- โWatch: must run Wear OS 3.0 or later. This is what actually makes a watch an "Android watch" for Lynio's purposes, not every watch marketed as Android-compatible qualifies. Check Settings > About watch on the watch itself, it should say "Wear OS by Google." If there's no Google Play Store on the watch, it isn't Wear OS.
- โWi-Fi: needed on the watch for the first-time installation, downloading the apps and completing setup happens over Wi-Fi (this is also how Lynio pushes a signed app bundle directly to a watch when needed, see Step 2). Not needed again once setup is done.
- โBluetooth: turned on, on your iPhone. Lynio pairs and stays connected over Bluetooth.
- โAndroid phone: needed briefly for initial setup on any Wear OS watch except Samsung Galaxy Watch, which never needs one, whether the watch is new or already set up. See Step 2 for the one other exception: an already-active watch with broken Google sign-in.
- โKeep Lynio running: installed and running in the background after setup, don't force-quit it. It reconnects automatically when your watch comes back in range, but it can't do that if it's been closed.
Step-by-Step Setup Guide
01
Download Lynio on your iPhone
- โOpen the App Store on your iPhone
- โSearch for "Lynio," or tap the Download button below
- โInstall the app and open Lynio
- โGrant Bluetooth permission when prompted
02
Install Lynio Watch on your watch
- โSamsung Galaxy Watch: open the Google Play Store on the watch, search "Lynio Watch," tap Install. No Android phone needed, at any point, whether the watch is brand new or already set up.
- โAny other Wear OS watch, new or not yet set up: you'll need an Android phone briefly for that first activation, that's a Wear OS requirement itself, not something Lynio can skip. Once the watch is active, install Lynio Watch the same way, from the watch's own Play Store.
- โAlready-active watch where Google sign-in isn't working: you don't need an Android phone either. Lynio can push a signed app bundle directly to the watch over Wi-Fi from your iPhone instead of going through the Play Store. Look for this option in the app if your watch is already set up but you can't sign in to Google on it.
- โWait for installation to finish (about a minute)
- โOpen the Lynio Watch app, it will show "Waiting for iPhone..."
๐ก Wi-Fi is required for this step: downloading and installing the watch app happens over Wi-Fi, whichever path applies to your watch.
03
Pair your devices
- โOpen Lynio on your iPhone
- โTap "Set Up Watch" and follow the pairing guide
- โMake sure your watch is within Bluetooth range (10 metres)
- โThe app scans and finds your watch automatically
- โConfirm the pairing code shown on both devices
- โYour watch shows "Connected." The Bluetooth handshake itself usually takes under 60 seconds once both apps are installed and ready
Total time for most users: 5 to 10 minutes, depending on your watch and whether you needed Android phone access to set up the watch first.
Supported watches
Any watch running Wear OS 3.0 or later works with Lynio: Samsung Galaxy Watch (Watch 4 and newer), Google Pixel Watch, TicWatch, Xiaomi Watch, Oppo Watch, OnePlus Watch, Fossil, Hublot, Montblanc, and TAG Heuer's Wear OS models.

Setup FAQs
Most users are done in 5 to 10 minutes total. That varies mainly by whether your watch needed Android phone access to set up first (see Prerequisites above); the final Bluetooth pairing step itself usually takes under 60 seconds once both apps are installed.
Make sure Bluetooth is enabled on your iPhone and your watch is within 10 metres. Use our Reconnect Guide inside the app for troubleshooting steps.
Only for some watches, not all. Samsung Galaxy Watch never needs one, whether it's new or already set up. Any other Wear OS watch needs brief Android access if it's new and not yet activated, that's a Wear OS requirement, not something Lynio can skip. If your watch is already active but Google sign-in isn't working on it, Lynio can push the watch app over Wi-Fi directly from your iPhone instead.
Wear OS puts apps to sleep aggressively to save battery, which is the most common reason a connection stops holding. Three settings on the watch fix it: take Lynio out of battery optimisation (Battery > Sleeping Apps, press and hold Lynio, choose Remove or Don't optimize), let it run in the background (Settings > Apps > App List > Lynio > Permissions, turn off "Pause App Activity if unused"), and allow health data collection in the background (Settings > Apps > App List > Lynio > Permissions > Sensors > Allow all the time). Menu names vary slightly by watch model and Wear OS version, look for the equivalent options if yours don't match exactly.
No, and you shouldn't. Leave Lynio running in the background, and make sure your iPhone isn't set to put it to sleep. It reconnects silently whenever your watch comes back in range, but a closed app can't reconnect on its own.
We've designed Lynio to handle car Bluetooth gracefully, this prevents watch disconnection when CarPlay is active.
iOS 17.6 or later on your iPhone, and Wear OS 3.0 or later on your watch.
Yes, you'll need internet access to download the app on your watch and the app on your iPhone, and to complete setup. After that, you don't need Wi-Fi.
This usually means the call audio mode hasn't turned on, even though your watch is already connected over Bluetooth. Lynio tries to turn this on automatically in the background, but if it doesn't, go to Settings > Bluetooth on your iPhone, then tap your watch's name under "My Devices." Since the watch is already connected, this isn't reconnecting anything, tapping it activates the audio mode that calls need.
Start on the watch. Open wireless debugging and tap Pair new device there first, before you try to connect from the phone. The pairing numbers change every time you tap Pair new device, so starting from the phone risks using an old number that no longer works. To check the numbers match, look for two things on the watch: an address like 192.168.1.45:39285 (the port number after the colon changes each time), and a 6 digit Wi-Fi pairing code, often shown with a space in the middle, like 482 915. Enter that code on the phone. This whole process needs Wi-Fi turned on.
It can happen if your watch goes out of Bluetooth range. Lynio automatically tries to reconnect once you're back in range, which usually takes 30 seconds to a minute, so give it a moment before trying anything else.
One code shows on your watch and a matching one shows on your iPhone, so both devices can confirm they agree on the same pairing before continuing. If you've tried again and still can't see them, connect from your iPhone's settings instead, that usually works. If it still doesn't, there may be a temporary glitch in the phone's software, turning your iPhone off and back on often clears this.
Yes to both, at least the first time you connect. After initial setup, only Bluetooth is needed for day to day syncing. Wi-Fi is only needed again if you're updating your watch's app through your phone.
Lynio needs to keep running in the background to keep your watch and iPhone in sync, so closing it can interrupt that. Opening the app again should reconnect things automatically, usually within 30 seconds to a minute. This only works if Bluetooth is turned on and your watch is connected.
First, open Lynio and check whether it shows you as connected to your watch. If it does, everything should be working as expected. If it doesn't, check that Bluetooth is turned on and that you've given the needed permissions on both your phone and your watch. Lynio will let you know if a permission is still pending.
