Introduction
Lefun Wear is a free companion app for Bluetooth-connected smartwatches and fitness bands, developed by Shenzhen TJD Information Technology Co., LTD (深圳市天金达信息技术有限公司). Designed to bridge the gap between your wrist and your phone, the Lefun Wear app syncs health and fitness data — including step counts, heart rate, blood pressure, sleep statistics, and calorie burn — from your smartwatch to your smartphone in real time.
With support for popular budget smartwatch models like the DT19, C6, HK49, eWatch, M9PRO, IE9, and various Ultra-style watches, Lefun Wear serves as a lightweight yet functional health monitoring hub for users who want to track daily wellness without expensive wearables.
How Lefun Wear Works
The Lefun Wear app connects to your smartwatch via Bluetooth Low Energy (BLE). Once you open the app and search for your device on the pairing screen, it establishes a stable connection and begins syncing health data automatically. The app displays your step count, distance, calories, heart rate readings, blood pressure data, and sleep duration on a clean home dashboard.
Beyond health data, Lefun Wear also acts as a notification relay: incoming phone calls, SMS messages, and select app notifications are pushed from your phone to your wrist, so you never miss important alerts while your phone is in your pocket or bag.
Health & Fitness Tracking
Step Counting and Daily Activity
Lefun Wear records your daily step count, distance traveled, and calories burned. The home screen displays today's progress at a glance, while historical data lets you review trends by day, week, month, or year through intuitive charts and statistics.

FAQ
What is the Lefun Wear app and what does it do?
Lefun Wear is a free companion app for Bluetooth-connected smartwatches and fitness bands, developed by Shenzhen TJD Information Technology Co., LTD. The app syncs health data from your smartwatch to your phone — including step counts, heart rate, blood pressure, sleep duration, and calorie burn. It also forwards call and SMS notifications from your phone to your watch. The app is available on both Android (Google Play) and iOS (App Store) and works with devices like the DT19, C6, HK49, eWatch, M9PRO, and other BLE-compatible smartwatches.
How do I connect Lefun Wear to my smartwatch?
To connect Lefun Wear to your smartwatch: (1) Download Lefun Wear from Google Play or the App Store, or scan the QR code on your watch's packaging; (2) Enable Bluetooth and Location services on your phone; (3) Open the Lefun Wear app and go to the device search/pairing page; (4) The app will scan for nearby Bluetooth devices — select your watch model from the list (e.g., 'C6'); (5) Confirm pairing on both devices and wait for the connection to establish. Important: On Android, location permission is required for Bluetooth scanning — this is an Android system requirement, not used for actual location tracking.
Why won't my Lefun Wear watch connect to my phone?
Common Lefun Wear connection troubleshooting: (1) Ensure Bluetooth and Location are both enabled on your phone (Android requires location for BLE scanning); (2) Make sure the watch is in pairing mode and within close range (1-2 meters); (3) Do not pair through your phone's Bluetooth settings directly — always connect through the Lefun Wear app; (4) If previously paired, remove the watch from the app and your phone's Bluetooth list, then re-pair; (5) Restart both your phone and smartwatch; (6) Check that the Lefun Wear app has notification access permission enabled; (7) Ensure you're using the correct app — Lefun Wear is different from Lefun Health, and each supports different watch models.
What smartwatches are compatible with Lefun Wear?
Lefun Wear supports various Bluetooth-enabled smartwatches and fitness bands including: DT19, C6 series, HK49, eWatch, M9PRO, IE9, and various Ultra-style budget smartwatches. The best way to confirm compatibility is to check your smartwatch's packaging or setup screen — if it shows a QR code that leads to 'Lefun Wear,' this is the correct app. Note: Some newer smartwatches from the same manufacturer may require the Lefun Health app instead.
What is the difference between Lefun Wear and Lefun Health?
Lefun Wear and Lefun Health are both developed by the same company (Shenzhen TJD Information Technology) but support different device models. Lefun Wear is the earlier app, designed for older smartwatch models like the DT19, C6, HK49, and M9PRO. Lefun Health is the newer, more actively updated app with a broader feature set — including richer watch face galleries, more advanced health data analysis, and support for newer devices. Check your smartwatch's packaging or QR code to determine which app your specific device requires.
Does Lefun Wear support blood pressure monitoring?
Yes, Lefun Wear can display blood pressure readings from compatible smartwatches that include a blood pressure sensor. The data syncs via Bluetooth and is shown on the app's home dashboard. Important: These readings are from consumer-grade wearable sensors and are for general wellness reference only. They should not be used for medical diagnosis or to replace professional blood pressure monitoring equipment. Always consult a healthcare professional for medical-grade blood pressure measurements.
How do I use the find phone feature in Lefun Wear?
The anti-lost / find phone feature works both ways on supported smartwatch models: (1) From watch to phone: Press the find phone button on your smartwatch — your phone will ring or vibrate even if it's on silent mode, helping you locate it. (2) From app to watch: Open the Lefun Wear app, go to device settings, and tap the find device option — your smartwatch will vibrate or beep to help you locate it. Both devices need to be connected via Bluetooth and within Bluetooth range for this feature to work.
Is the Lefun Wear app free to use?
Yes, Lefun Wear is completely free to download and use on both Android and iOS. There are no subscription fees, no premium tiers, and no in-app purchases. All features — health tracking, notifications, watch face management, and device management — are available at no cost. The app is monetized through the sale of compatible smartwatch hardware by the developer.
Can I customize the watch face with Lefun Wear?
Yes, on compatible smartwatch models, Lefun Wear allows you to customize your watch face (dial). You can choose from available watch face designs within the app and push them to your watch via Bluetooth. Some models also support custom dial features where you can create personalized watch faces. The watch face customization feature was added in version 1.17 and has been improved in subsequent updates.
How accurate is the health data from Lefun Wear?
Lefun Wear health data (heart rate, blood pressure, sleep, steps) uses optical sensors built into your smartwatch. Step counting and heart rate monitoring are generally reliable for daily wellness tracking and fitness trend monitoring. However, blood pressure readings from wrist-based sensors are less accurate than dedicated medical devices. All measurements from consumer smartwatches are for general reference only and should not be used for medical diagnosis. Factors like wrist position, skin type, movement, and sensor fit can affect accuracy.
User Reviews

App Store
Lefun Wear pairs quickly with my DT19 watch. Step counting and heart rate tracking work well. The interface is simple and easy to navigate. I appreciate that it syncs time and weather to the watch automatically. Wish it had more watch face options though.

Pricing InfoFree to download and use on both Android and iOS. No subscription required. No in-app purchases. All health tracking, notification, and device management features are included at no cost.
Basic app that does what it needs to do. Steps, heart rate, and sleep tracking all work. Blood pressure readings seem reasonable but I wouldn't rely on them medically. The find phone feature has been useful a couple of times. Connection is mostly stable.
App Store
For a free companion app, Lefun Wear does a solid job. Health data syncs reliably and the dashboard is clean. Call and SMS notifications work well on my C6 watch. The app could use a UI refresh but functionality is good for daily tracking.
App Store
The app works fine for checking my daily steps and sleep data. Heart rate monitoring is consistent. I like that it's lightweight and doesn't drain my phone battery. Historical data charts are helpful for tracking trends over time.
App Store
Setup was straightforward — scanned for my watch and connected in about 30 seconds. All the basic health features work as expected. The anti-lost feature is a great addition. Would love to see integration with Apple Health in future updates.
Google Play
Good app for my budget smartwatch. Connected easily and health tracking works — steps, heart rate, blood pressure all sync properly. Notifications from WhatsApp and calls come through to the watch. The app is light and doesn't use much battery.
Google Play
Does the basics well. I use it mainly for step counting and call notifications on my smartwatch. Sleep tracking is decent — shows total duration. The interface is a bit dated but functional. Free and works without any premium upsells.
Google Play
Lefun Wear works reliably with my HK49 watch. Bluetooth connection stays stable throughout the day. Heart rate and step data are accurate enough for daily monitoring. The weather sync feature is a nice touch. Simple app that does its job.
Google Play
The app is straightforward — pair your watch and start tracking. Blood pressure and heart rate data display clearly on the home screen. I wish the sleep analysis was more detailed with light vs deep sleep stages. Overall functional for a free app.
Google Play
Been using Lefun Wear with my M9PRO for six months. The app is stable and syncs data quickly. I check my daily steps and heart rate every morning through the dashboard. The sedentary reminder keeps me moving during work hours. Solid companion app.

App Notification Forwarding
Configure push notifications from messaging and social apps to your watch, keeping you connected without constantly reaching for your phone.

Some compatible watches support a find-phone feature — trigger an alert on your phone from the watch, or locate your watch by triggering it from the app. This is especially useful if you misplace either device.
Device Management
Time & Weather Sync
Lefun Wear automatically synchronizes your phone's time and weather data to the smartwatch, ensuring your watch always displays the correct time and current weather conditions.
Watch Face Customization
On compatible models, customize your smartwatch's watch face (dial) — choose from available designs or push custom dials to your watch via Bluetooth.
Device Search & Pairing
The app provides a device search page that lists compatible smartwatches. Simply scan for nearby devices, select your watch model (e.g., "C6"), and confirm the pairing.
Compatible Devices

If your smartwatch's packaging or QR code directs you to download "Lefun Wear," this is the correct application for your device.
Lefun Wear vs Lefun Health
Lefun Health is a newer, more actively updated companion app from the same developer. While Lefun Wear provides core health tracking and notification features, Lefun Health offers a broader feature set including richer watch face galleries, more advanced data analysis, and support for a wider range of newer devices. If your watch supports both apps, Lefun Health may provide a more modern experience — but Lefun Wear remains the correct app for older devices that specifically require it.
Privacy & Data
Lefun Wear is published by Shenzhen TJD Information Technology Co., LTD. The app requests Bluetooth, Location (required for BLE scanning on Android), and notification access permissions. Health data is stored locally on your device and synced to the paired smartwatch.
Important: Lefun Wear-compatible smartwatches are consumer wellness devices, not medical devices. All health measurements (heart rate, blood pressure, sleep data) are for general reference only and should not be used for medical diagnosis or treatment decisions.
