WhatsApp on Apple Watch requires your iPhone first
You cannot install WhatsApp directly on an Apple Watch. The app must be on your iPhone first, and then you can add a companion app to your watch. Your iPhone and Apple Watch must be paired together, connected to the same Wi-Fi network or Bluetooth, and both running current software. WhatsApp on the watch lets you read and reply to messages without pulling out your phone, but it syncs through your iPhone — the watch version does not work independently.
The process takes about five minutes once you have WhatsApp on your iPhone. If you do not have WhatsApp installed yet, start there before moving to the watch.
Key Takeaways
- WhatsApp must be installed on your iPhone before you can use it on your Apple Watch.
- Your iPhone and Apple Watch must be paired and connected to the same network for the watch app to work.
- You install the watch version through the Watch app on your iPhone, not through the watch itself.
- The Apple Watch version lets you read messages and reply with preset responses or voice, but cannot initiate new conversations.
Make sure your iPhone has WhatsApp installed and updated
Open the App Store on your iPhone and search for WhatsApp Messenger. If it is already installed, open the App Store, tap your profile icon in the top right, and scroll down to see if an Update button appears next to WhatsApp. If it does, tap Update. You need a version from the last few months for the watch app to work properly.
Once WhatsApp is updated on your iPhone, sign in or create an account if you have not already. The watch app will not function without an active WhatsApp account on your phone.
Open the Watch app on your iPhone and find WhatsApp
On your iPhone, open the Watch app (the icon looks like a small watch face). Tap the My Watch tab at the bottom. Scroll down until you see WhatsApp in the list of available apps — you may need to scroll past several other apps to find it.
Tap WhatsApp. You should see a toggle switch next to "Show App on Apple Watch" or similar wording. Make sure this toggle is turned on (it will be green or blue). This tells your iPhone to install the companion app on your paired watch.
Wait for the app to sync to your watch
After you turn on the toggle, your iPhone will send the WhatsApp app to your Apple Watch. This usually takes one to three minutes. Your watch and iPhone must be close together and connected — if your watch is not paired or is out of Bluetooth range, the sync will not happen.
You can check the status by looking at your Apple Watch. Swipe up from the bottom of the watch screen to open Control Center and look for the Bluetooth icon. If it shows a line through it, your watch is not connected to your iPhone. Move them closer together or restart both devices if the connection drops.
Open WhatsApp on your Apple Watch to finish setup
Once the app has synced, open WhatsApp on your Apple Watch by pressing the Digital Crown (the button on the side) and scrolling to find the WhatsApp icon, or swipe left on your watch face to access the app drawer. Tap WhatsApp to open it.
The first time you open it, you may see a message saying it is setting up or syncing with your iPhone. Wait a few seconds. Your recent conversations from your iPhone should appear on the watch screen. If nothing shows up after 30 seconds, close the app and open it again.
Know what you can and cannot do on the watch version
WhatsApp on Apple Watch lets you read incoming messages and reply using preset quick responses like "Thanks" or "OK", or by speaking a voice message. You can also see who is online and whether messages have been read. You cannot start a new conversation from the watch, search for old messages, or make calls — those features only work on your iPhone.
If someone sends you a message while your iPhone is locked, you will still see the notification on your watch. Replying from the watch sends the message through your iPhone, so your iPhone must be powered on and connected to the internet for messages to actually send.
Troubleshooting if WhatsApp does not appear on your watch
If you turned on the toggle in the Watch app but WhatsApp still does not show up on your watch, restart both devices. On your iPhone, hold the side button and one volume button until the power-off slider appears, then slide to power off. Wait 10 seconds and turn it back on. On your Apple Watch, hold the side button until you see the power-off slider, then slide to power off.
After both devices restart, check the Watch app again and make sure the WhatsApp toggle is still on. If it is off, turn it back on and wait another two to three minutes. If WhatsApp still does not appear, make sure your iPhone and watch are running the latest software by going to Settings > General > Software Update on your iPhone and Settings > General > Software Update on your watch.
Frequently Asked Questions
Can I use WhatsApp on my Apple Watch without my iPhone nearby?
No. The watch app only works when your iPhone is powered on and connected to Wi-Fi or cellular data. The watch cannot send or receive messages on its own. If your iPhone is off or out of range, WhatsApp on your watch will not work.
Why does WhatsApp not show up in my Watch app settings?
WhatsApp may not appear if your iPhone is running an older version of iOS or your Apple Watch is running an older version of watchOS. Go to Settings > General > Software Update on both devices and install any available updates. You may also need to update WhatsApp itself through the App Store.
Can I start a new conversation from my Apple Watch?
No. You can only reply to messages that come to you. To start a new conversation, you must use your iPhone. The watch version is designed for quick replies to incoming messages, not for initiating contact.
What happens if I uninstall WhatsApp from my iPhone?
The watch version will stop working when ready. Your watch app is linked to the iPhone version, so removing WhatsApp from your phone removes it from your watch as well. Reinstalling WhatsApp on your iPhone will restore the watch app after a few minutes of syncing.
