How to Connect Google Pixel Watch 4 to Your iPhone.
Yes. The Pixel Watch 4 works with iPhone. Google publishes no iOS app, so pair it with Lynio instead and you get calls, notifications, contacts and health sync in about 3 minutes. See how
Google's fourth watch: the domed Actua 360 display at 3,000 nits, a Snapdragon W5 Gen 2, and the first Pixel Watch you can open and repair.
About the Google Pixel Watch 4
Released October 2025 from $349.99, and the first Pixel Watch Google designed to be opened. Two screws under the band pocket let you replace the battery or display without heat or adhesive, and it still holds 5ATM and IP68. Every earlier Pixel Watch was effectively disposable. The display is new too, a domed panel peaking at 3,000 nits with slimmer bezels, and charging moved to a side-mounted magnetic dock that needs at least 7.5W.
On LTE models, satellite SOS calls for help with no phone and no cell coverage, which Google claims as a smartwatch first. Google guarantees updates through October 2028, three years from its US on-sale date. That is a shorter window than Samsung offers, and worth knowing before you spend $499 on a 45mm LTE.

Connect in 3 Steps
Install Lynio Watch on your Google Pixel Watch 4
From the Play Store on the watch. If Google sign-in will not work there, Lynio sends the app across as a signed bundle over Wi-Fi instead.
Follow the in-app pairing guide
Keep both on the same Wi-Fi, Bluetooth on, and leave the app open until pairing finishes.
What You Get After Pairing
| Works | Does not carry over |
|---|---|
| Notifications from your iPhone | Google Wallet payments from the wrist |
| Calls, made and answered from the wrist | Gemini's phone-side features |
| Contacts synced from the iPhone | Fitbit's phone app and its coaching |
| Music playback control | Ultra-wideband phone unlock and car key |
| Workouts and health data written to Apple Health | Google Assistant routines |
| On-watch sensors, GPS, the repairable hardware |
Satellite SOS runs on the watch's own LTE rather than through your phone, so the capability stays on the device. Whether it is available to you depends on your carrier and country, and it is on LTE models only. Confirm it before buying for that reason.
