How to connect TicWatch Pro 3 to iPhone

The TicWatch Pro 3 was the first Wear OS watch to ship Qualcomm's Snapdragon Wear 4100 chip, and it paired that performance advantage with a dual-display system - a full AMOLED beneath an FSTN reflective layer - capable of 45-day Essential Mode battery life. A figure that still stands out. Wear OS offers no native iPhone pairing; Merge provides it: install on both devices and Pro 3 connects to your iPhone for notifications, Apple Health sync, contacts, music control, and camera control.

What works with iPhone

Paired through Merge, the TicWatch Pro 3 becomes a capable iPhone companion. Notifications from every app on your iPhone arrive on the watch in real time, with per-app controls to keep alerts focused. Health data syncs to Apple Health via Merge: heart rate, steps, distance, floors climbed, calories, workouts with GPS routes, and pace all route through Merge's health bridge - useful for runners using the watch's standalone GPS during long training runs where the iPhone stays home.

iPhone contacts sync to the watch for wrist-level access - handy on the long hikes where the 45-day Essential Mode battery becomes relevant. Music playback and volume are controllable from the watch, so you can adjust volume mid-hike without breaking pace or reaching for your phone. Camera control lets you trigger the iPhone remotely when the camera app is open. In Smart Mode, three days of real-world use with always-on heart rate and active Merge notifications is achievable.

Android phone required for first-time activation

First-time activation on the Pro 3 requires a Google account sign-in through the Wear OS by Google app on Android. There is no dedicated iPhone path to skip this step. The practical solution is a brief loan of someone's Android device - turn on the watch, connect it to the Android phone via Bluetooth, sign in with a Google account, and let the watch complete its initial configuration. Give it 10-15 minutes. Once the setup wizard closes, the Android phone is finished. Your iPhone and Merge handle everything that follows.

Pairing TicWatch Pro 3 with iPhone using Merge

1. Complete the TicWatch Pro 3's initial activation using an Android phone and the Wear OS by Google app.
2. On your iPhone, search the App Store for Merge Watch and install it.
3. On the TicWatch Pro 3, open Play Store, search for Merge Watch, and install it.
4. Open Merge on your iPhone - approve the Bluetooth permission when prompted, then keep it foregrounded.
5. On the TicWatch Pro 3, open Merge and approve the Bluetooth permission when prompted.
6. Tap Start Pairing - the watch stays discoverable for five minutes.
7. On your iPhone, open Settings → Bluetooth and wait for the watch to appear in the list, then tap it to pair.
8. Once paired, your iPhone will appear in Merge on the watch - tap it to complete the connection.
9. Set up your Merge subscription via the iPhone app if prompted.
10. Grant notification and health permissions on both devices when asked.

Using the TicWatch Pro 3 day to day with iPhone

The 45-day Essential Mode ceiling is the Pro 3's defining advantage for iPhone users who travel or find themselves away from a charger for extended periods. In Essential Mode, the AMOLED shuts off entirely and the secondary FSTN LCD takes over, showing time, steps, and heart rate via a dedicated co-processor - with no phone connection required. When you return to Bluetooth range and switch back to Smart Mode, Merge reconnects and resumes the full notification relay without re-pairing. Notification delivery with no charging gaps across an extended trip is a practical advantage that most Wear OS watches can't match. The 595mAh battery is one of the largest ever fitted to a Wear OS watch, and it shows in the three-day Smart Mode real-world performance.
