Da Fit is one of the world's most popular free smartwatch companion applications, with over 50 million downloads across Android and iOS. Developed by Mo Young Limited, the Da Fit app serves as the central hub for connecting, configuring, and monitoring data from a wide range of affordable and mid-range smartwatches — making it one of the most widely deployed companion apps in the budget wearables segment.
If you recently purchased a budget smartwatch and it asks you to download the Da Fit app, this guide covers everything you need to know: how to connect your device, what features are available, how to troubleshoot common issues, and whether Da Fit is the right app for you.
What Smartwatches Are Compatible with Da Fit?
The Da Fit app is compatible with a large ecosystem of third-party smartwatches and fitness bands, particularly affordable Chinese-brand wearables. Popular Da Fit compatible smartwatches include:
- Colmi (Land 1, P8, P45, P68, and many more)
- Bakeey (SN67, S23, and related models)
- Kospet (Raptor and series watches)
- Senbono (P8, P4 series)
- Umidigi (Uwatch 2S)

- Hundreds of other budget smartwatch brands using the Mo Young / Da Fit protocol
To check if your watch is compatible: Open the Da Fit app, tap the "+" icon, and search for your watch model. If it appears in the scan results or the supported device list, your watch is compatible.
Core Features of the Da Fit App
Activity & Fitness Tracking
The Da Fit watch app tracks your daily step count, distance walked, and estimated calories burned. Data syncs from your watch to the app via Bluetooth and is presented in clear daily and weekly charts. The app shows when your activity was highest throughout the day and allows you to set step goals.
Sleep Monitoring
Da Fit records your sleep duration and sleep stages — light sleep and deep sleep — based on your watch's motion sensors. The app displays a nightly sleep summary and historical trends, making it easy to spot patterns over time. Users can also configure a gentle smart alarm based on sleep data to wake up at the optimal point in their sleep cycle.
Heart Rate Monitoring
For Da Fit smart watch models that support heart rate sensors, the app can display continuous or periodic heart rate readings with daily graphs. Newer models also support:
- Blood oxygen (SpO₂) — spot readings or continuous monitoring
- Stress level — measured via HRV analysis
- Body temperature — on devices with temperature sensors
Watch Face Customization
One of Da Fit's most popular features is its watch face library with hundreds of free downloadable designs — from classic analog styles to sporty digital displays. You can browse and apply new watch faces directly from the app. Some models also support setting a custom photo as your watch face.
Notification Forwarding
Once Bluetooth is connected and permissions are granted, Da Fit forwards phone notifications to your watch:
- Incoming calls
- SMS messages
- WhatsApp, Facebook, Instagram, and other app alerts
- Configurable Do Not Disturb scheduling
Smartwatch Utilities
- Find My Watch — makes the watch vibrate to help locate it
- Find My Phone — trigger phone ringtone from the watch
- Remote camera shutter — use the watch as a camera trigger
- Music control — play/pause and skip tracks from your wrist
- Weather display — current and forecast weather on the watch
- World clocks and alarms
How to Connect Your Smartwatch to Da Fit
Setting up the Da Fit app is straightforward:
- Download Da Fit from the Google Play Store or Apple App Store
- Open the app and grant required permissions: Bluetooth, Location (required for Bluetooth scanning on Android), and Notifications
- Tap the "+" (Add Device) button on the home screen
- Enable Bluetooth on your phone and make sure your watch is powered on
- Select your watch model from the scanned device list — or scan the QR code shown on some watch models
- Confirm the pairing request and wait for initial sync to complete
- Enable notification forwarding for your desired apps in Device Settings → App Notifications
Tip: On Android, if Da Fit loses connection frequently, add it to your phone's battery optimization whitelist. Most connection issues are caused by the operating system killing Da Fit in the background.
Da Fit vs VeryFit — What's the Difference?
Both Da Fit and VeryFit are popular companion apps for budget Chinese smartwatches, but they serve different watch ecosystems:
| Feature | Da Fit | VeryFit |
|---|---|---|
| Developer | Mo Young Limited | Shenzhen Airy Technology |
| Compatible watches | Mo Young / CRREPA protocol devices | Bozlun / iWOWN protocol devices |
| Downloads | 50M+ | 10M+ |
| App Store rating | 4.7★ | ~4.0★ |
| Watch faces | Hundreds available | Limited selection |
| Health metrics | Steps, sleep, HR, SpO₂, stress, temp | Steps, sleep, HR, SpO₂ |
| Integration | Apple Health, Google Fit | Apple Health |
Bottom line: If your smartwatch instruction manual points you to Da Fit, use Da Fit. The apps are not interchangeable — each only works with its own ecosystem of compatible devices.
Does Da Fit Sync with Apple Health or Google Fit?
Apple Health: Yes. Da Fit supports Apple Health App Sharing on iOS. To enable it: go to iPhone Settings → Health → Data Access & Devices → Da Fit and authorize the data types you want synced (steps, heart rate, sleep, etc.).
Google Fit: Da Fit can sync data with Google Fit on Android, though some users report intermittent sync issues. To troubleshoot: ensure Da Fit has Fitness Activity permissions, verify Da Fit appears under Google Fit → Connected Apps, and manually trigger a sync in Da Fit if data hasn't appeared.
Samsung Health: Da Fit does not have a native Samsung Health integration. Data can sometimes be transferred via Google Fit as an intermediary on Android, but this is not officially supported.
Da Fit App Privacy and Security
Da Fit collects the following data based on Mo Young's official privacy policy:
- Personal information (name, email if account created)
- Health and activity data (steps, sleep, heart rate)
- Device identifiers and app usage logs
- Location (optional, for Bluetooth scanning; may be used in background)
Key privacy points:
- Data is encrypted in transit between the app and servers
- Some data (location, device IDs, diagnostics) may be shared with third parties, including advertisers
- The app does not provide an in-app data deletion option — to request deletion, contact Mo Young support directly
- A 2025 third-party security audit (BeVigil) reported 50+ medium-risk vulnerabilities and gave Da Fit a security score of 6.4/10
Our assessment: Da Fit is acceptable for everyday fitness tracking on budget wearables, but it is not recommended for sensitive health data or users with strict privacy requirements. Privacy-focused users may prefer Gadgetbridge, an open-source Android app that stores all data locally and supports many Da Fit–compatible watch models.
Troubleshooting Common Da Fit Problems
Da Fit Not Connecting
- Ensure Bluetooth is enabled on your phone

- As a last resort: uninstall and reinstall Da Fit
Who Is Da Fit For?
The Da Fit app is an excellent choice for:
- Budget smartwatch buyers who want a reliable companion app for their affordable wearable
- Casual fitness trackers who need basic step counting, sleep monitoring, and heart rate data without complex analytics
- Watch face enthusiasts who want access to hundreds of free customizable designs
- Multi-watch users — Da Fit can manage multiple compatible devices from one app

It is not ideal for:

- Privacy-conscious users tracking sensitive health conditions
- Users who need verified medical-grade health data
Note: Da Fit is not a medical device. All health data provided is for general wellness reference only and should not be used for medical diagnosis or treatment decisions.
