Introduction
U-Watch is the official companion app for HUAXIN smartwatches and fitness wearables, developed by Anhui Huaxin Electronic Technology Co., Ltd. (HUAXIN TECHNOLOGY). With over 1 million downloads on Google Play and a steadily growing iOS user base, U-Watch bridges your HUAXIN wearable device with your smartphone — delivering health data synchronization, sports tracking, watch customization, and smart notifications in one unified interface.
Designed primarily for users of affordable HUAXIN phone watches and fitness bands, the app provides a straightforward health monitoring experience with step counting, heart rate tracking, sleep analysis, and blood pressure readings via Bluetooth connectivity.
How U-Watch Works
U-Watch connects to your HUAXIN smartwatch via Bluetooth Low Energy (BLE). Once paired, the app continuously syncs health data — steps, heart rate, sleep duration, blood pressure readings, and sport session records — from your wrist to your phone. Data is displayed in clean daily dashboards so you can monitor health metrics at a glance.
The app also acts as a notification bridge: incoming calls, SMS, and app alerts are forwarded from your phone to your watch, keeping you connected without constantly checking your phone.
Health & Fitness Tracking
Step Counting and Daily Activity
U-Watch records your daily step count, distance traveled, and calories burned. The health dashboard provides clear visualizations of your daily activity progress against personal goals.
Heart Rate Monitoring
Real-time heart rate tracking captures data throughout the day and during workouts. The U-Watch app displays your HR history in chart form, making it easy to spot cardiovascular trends.

U-Watch is the official companion app developed by Anhui Huaxin Electronic Technology Co., Ltd. (HUAXIN TECHNOLOGY) for HUAXIN smartwatches and fitness wearables. After pairing your watch via Bluetooth, the app serves as your health dashboard and device manager — displaying step counts, heart rate history, sleep data, blood pressure readings, and sports records. It also forwards call alerts, SMS, and third-party app notifications from your phone to your watch, and lets you customize watch settings. The app is free on both Android (Google Play, 1M+ downloads) and iOS (App Store).
How do I connect U-Watch to my phone?
To connect U-Watch to your phone: (1) Download U-Watch from the Google Play Store (package: com.sinophy.smartbracelet) or Apple App Store (ID: 6444815466); (2) Open the app and create an account or log in; (3) Enable Bluetooth and location services on your phone; (4) Power on your HUAXIN smartwatch; (5) In the U-Watch app, tap the device section and select 'Add Device'; (6) Select your watch from the scan list; (7) Confirm the pairing on both phone and watch. Once connected, grant notification access when prompted for full functionality.
Why is my U-Watch app not working or not connecting?
Common U-Watch connection issues and fixes: (1) Bluetooth off — ensure Bluetooth is enabled on your phone; force-close the app and reopen it. (2) Watch out of range — keep phone and watch within 1–2 meters during initial pairing. (3) Cache issue — go to phone Settings > Apps > U-Watch > Storage, clear cache and data, then relaunch. (4) Time sync issue — if your watch shows incorrect time after syncing (off by 12 hours), update to the latest app version (v2.5.7+ fixes this). (5) Reinstall — uninstall and reinstall the app, then re-pair the watch. (6) Restart both devices — power off both your phone and watch, then restart and try again.
Which watches are compatible with U-Watch?
U-Watch is designed for HUAXIN-branded smart wearables, including phone watches and fitness bands produced by Anhui Huaxin Electronic Technology Co., Ltd. If your watch's packaging shows a QR code or instructions pointing to U-Watch (or the app store listing for com.sinophy.smartbracelet), this is the correct app. The app primarily supports affordable Chinese smartwatches from the HUAXIN product line. If your device is not from HUAXIN, check your watch's documentation for the correct companion app.
Is the U-Watch app free?
Yes, U-Watch 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, sports modes, notifications, watch customization, and device management — are available at no cost.
Does U-Watch support heart rate and blood pressure monitoring?
Yes. U-Watch supports heart rate monitoring and blood pressure readings for compatible HUAXIN devices. Heart rate data is tracked continuously and displayed in chart form. Blood pressure readings are synced from your watch to the app. Important: these are consumer-grade wellness readings from optical sensors, not medical-grade measurements. They should not be used for medical diagnosis. For medical concerns, consult a healthcare professional.
How accurate is the health data from U-Watch?
U-Watch health data (heart rate, blood pressure, sleep, steps) uses sensors in your HUAXIN smartwatch to provide consumer-grade wellness readings. While generally useful for daily health monitoring and fitness trends, these measurements are not medical-grade. Step counting provides reasonable accuracy for tracking daily activity. Sleep tracking records duration but may not differentiate sleep stages as precisely as higher-end devices. For medical concerns, always consult a healthcare professional.
Does U-Watch support sleep tracking?
Yes. U-Watch provides sleep duration tracking for supported HUAXIN devices. It records your total sleep time and displays the data in the health dashboard. You can view daily sleep records to monitor your rest patterns over time. For best accuracy, wear your watch while sleeping and ensure Bluetooth stays connected to your phone.
Can I receive notifications on my watch through U-Watch?
Yes. U-Watch forwards notifications from your phone to your watch, including incoming calls (with caller ID), SMS messages, and third-party app notifications from WhatsApp, Facebook, Telegram, and other apps. To enable: make sure Bluetooth is connected, then grant notification access permission in the app settings. You can configure which apps' notifications are forwarded to your watch.
Is U-Watch safe to use? What about privacy?
On the App Store, the developer (Anhui Huaxin Electronic Technology Co., Ltd.) declares 'Data Not Collected' — meaning the app does not collect personal data. On Google Play, data is encrypted in transit and users can request data deletion. The app's privacy policy is available at the developer's website. U-Watch requires Bluetooth and location permissions for device pairing and functionality, which is standard for smartwatch companion apps.

I've been happy with the watch so far. I am horrible about breaking my watches so I wasn't going by another $300 Apple Watch. This thing does everything I needed to do gives me notifications keeps up with my steps in my sleep. The steps aren't the most accurate but the sleep seems to be.

I love the watch but it has minor bugs to fix. The volume is not working and we need a new update. Overall the app works well for connecting the watch and syncing data. Notifications come through reliably.
App Store
Great value for the cost. The U-Watch app pairs easily with my watch and health tracking works as expected. Step counting and sleep monitoring are useful features. Would like to see more watch face options in future updates.
App Store
Good companion app for budget smartwatches. Heart rate monitoring works well and the data syncs reliably to my phone. The interface is simple and easy to navigate. Bluetooth connection stays stable throughout the day.
App Store
The app does what it needs to. Health data syncs properly and notifications work fine. However, the UI could use some modernization and the watch face selection is limited. For a free app with a budget watch, it's acceptable.
Google Play
Works well with my phone watch from HUAXIN. Bluetooth pairing was straightforward and health data displays correctly. Step counting is reasonably accurate and sleep tracking gives useful insights. The notification forwarding for calls and messages works great.
Google Play
Good app for managing my smartwatch. Heart rate and step tracking work reliably. The sleep data helps me understand my rest patterns. One minor issue: weather information doesn't always update correctly, but everything else runs smoothly.
Google Play
Basic functionality is solid — step counting, heart rate, and notifications all work. The multi-language support is appreciated. My main issue is that Bluetooth sometimes disconnects and needs manual reconnection. Also wish there were more sport modes available.
Google Play
Really useful for a budget smartwatch companion app. The health dashboard is clean and informative. Blood pressure and heart rate readings display nicely in chart form. The camera remote feature is a nice bonus. Recommended for HUAXIN watch users.
Google Play
The app functions well for daily health monitoring. Step tracking, sleep data, and notifications all work as expected. The interface is straightforward if a bit basic. Would like to see improvements to the watch face store and more customization options.
