wwfit

wwfit is a free Bluetooth companion app for budget smartwatches and fitness trackers, developed by yuan zhongli (developer ID 639663675) for Android and 明华 张 for iOS. Once you pair your smartwatch with the wwfit app over Bluetooth, it syncs your health data — daily steps, walking distance, calorie burn, sleep stages, and heart rate — from your wrist to your smartphone. The app also forwards incoming calls, SMS messages, and third-party app notifications (WhatsApp, Facebook, WeChat, etc.) from your phone to your watch in real time. It supports GPS running mode, watch face customization, sedentary reminders, and smart alarms. wwfit is free on both Google Play (1M+ downloads) and the iOS App Store.

To connect wwfit to your smartwatch: (1) Download the wwfit app from Google Play (package: com.wwfit.wwfit) or the App Store (ID: 1569353153); (2) Enable Bluetooth on your phone and open wwfit; (3) On Android, enable location services if prompted — this is required for Bluetooth scanning; (4) Power on your smartwatch and ensure it is discoverable; (5) In the wwfit app, tap the device connection option and scan for nearby devices; (6) Select your watch from the list and confirm pairing; (7) Grant notification access when prompted to enable call and app forwarding. Once connected, health data will begin syncing automatically.

Common wwfit connection issues and solutions: (1) Bluetooth off — enable Bluetooth on your phone and restart wwfit. (2) Location permission denied — on Android, Bluetooth LE scanning requires location access; grant it in phone settings. (3) Too far apart — keep your phone and watch within 1–2 meters during pairing. (4) Already paired elsewhere — remove the watch from your phone's Bluetooth list and unpair in wwfit, then pair fresh. (5) App needs updating — check the Play Store or App Store for the latest wwfit version. (6) Restart both devices — power off your phone and watch, then turn them back on and try again. (7) Wrong app — confirm your watch's QR code or manual specifies wwfit (com.wwfit.wwfit), not WWFIT 2.0 (com.limit.wwfit), which is a different app.

wwfit is compatible with a wide range of budget Bluetooth smartwatches and fitness trackers, primarily generic Chinese-made devices sold under various brand names. These include affordable smartwatch models styled after popular brands (Series 6/7 style clones), the WWFIT Band (PF-CW13Pro model), G20_LE trackers, and similar fitness bands that ship with a wwfit QR code. There is no official published compatibility list — the easiest way to confirm compatibility is to check whether your watch's box or manual includes a QR code that links to the wwfit app, or instructs you to search for 'wwfit' in the app store. Requires Android 4.3+ or iOS 12.0+.

Yes. wwfit detects and records your sleep data each night, separating deep sleep from shallow sleep stages and showing total sleep duration. The data syncs from your smartwatch to the app, where you can view your sleep breakdown for each night. To get accurate results, wear your bracelet or watch while sleeping and keep Bluetooth connected. The app displays your sleep history so you can monitor patterns and work on improving your rest quality.

To change your watch face in wwfit: (1) Open the wwfit app and ensure your smartwatch is connected; (2) Navigate to the Device section; (3) Look for the 'Dial Push' or watch face option; (4) Browse the available dial designs in the store; (5) Select your preferred face and tap to sync it to your watch. The new face downloads via Bluetooth and applies to your smartwatch. Note: some users report that the custom photo watch face feature does not work reliably on all compatible devices.

Yes, wwfit is completely free to download and use on both Android and iOS. There are no subscription fees, premium tiers, or in-app purchases. All features — step tracking, sleep monitoring, heart rate, GPS running, watch face customization, call and SMS notifications, sedentary reminders, smart alarms, and find my bracelet — are available at no cost.

The wwfit app supports 15+ languages. The Android version (Google Play) lists: Chinese (Simplified), Chinese (Traditional), English, German, French, Japanese, Russian, Spanish, Italian, Malay, Polish, Portuguese, Korean, Thai, and Vietnamese. The iOS version additionally supports Arabic, Cambodian, Hebrew, and Turkish. You can switch the app language from within your phone's language settings.

According to the Google Play data safety section, wwfit does not share data with third parties. However, it does collect health and fitness data, this data is not encrypted in transit, and users cannot delete their data through the app. On iOS, the developer states that no data is collected from the app. The app requires Bluetooth and location permissions on Android for device scanning.

As with all budget smartwatch companion apps, exercise caution about what personal information you store in the app.

wwfit (com.wwfit.wwfit) and WWFIT 2.0 (com.limit.wwfit) are two separate apps for different device families. wwfit — this app — is developed by 639663675 (yuan zhongli) and has 1M+ downloads with a 2.1-star rating on Google Play. It supports a broad range of generic budget smartwatches and fitness bands. WWFIT 2.0 is developed by Tom Tong (童文萍), also has 1M+ downloads but with a higher 3.4-star rating, and is specifically designed for the WWFIT Band (PF-CW13Pro model). If your watch's QR code leads to wwfit, use this app. If it specifies WWFIT 2.0, use that one instead.
