How to Connect TicWatch E3 to Your iPhone.
Yes. The TicWatch E3 works with iPhone. Mobvoi's own route is limited and the line has been discontinued, so pair it with Lynio instead and you get calls, notifications, contacts and health sync in about 3 minutes. See how
A flagship Snapdragon Wear 4100 in a $199 plastic body, at 32g the second lightest watch in this list.
About the TicWatch E3
Released June 2021 at $199.99, and an unusual proposition: Mobvoi put the same Snapdragon Wear 4100 from its $299 flagship into a polycarbonate case and sold it for a hundred dollars less. At 32g it is the second lightest watch in this directory.
The savings show in the screen. It is a single-layer 1.3in panel at 360 x 360, so there is no dual-layer display, and it is a lower resolution than almost anything else here. It also has no ambient light sensor, so brightness is a manual five-step setting, and no barometer or altimeter.
It still has Essential mode, which Mobvoi rates at over 20 days from a full charge and which auto-engages below 5% to keep showing time, steps and heart rate. On software it shipped on Wear OS 2, got Wear OS 3 in December 2023 and Wear OS 3.5 by late January 2024. Nothing since. Mobvoi pulled TicWatch listings in December 2025 and said only that existing devices would keep receiving essential support.

Connect in 3 Steps
Install Lynio Watch on your TicWatch E3
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 | Mobvoi's phone app and its history |
| Calls, made and answered from the wrist | Google Wallet payments from the wrist |
| Contacts synced from the iPhone | |
| Music playback control | |
| Workouts and health data written to Apple Health | |
| Essential mode, GPS, every on-watch sensor |
Note that 8GB of storage and 1GB of RAM is the real constraint on this watch. Keep the number of installed apps low and it stays responsive.
