Introduction
FlagFit is a free companion app for Bluetooth Low Energy (BLE) fitness trackers and smart bands, developed by Shenzhen Ultra Easy Technology Co., Ltd. (UTE). With over 500,000 downloads on Google Play, FlagFit connects your compatible smart band to your smartphone — delivering step tracking, sleep monitoring, heart rate readings, blood pressure estimates, GPS trajectory recording, and smart notifications in one lightweight app.
Designed primarily for budget-friendly BLE fitness bands such as the DB02, Watchitude Move, and other UTE-compatible wearables, FlagFit provides an accessible entry point into personal health monitoring without requiring expensive hardware or subscription fees.
How FlagFit Works
FlagFit pairs with your smart band via Bluetooth Low Energy (BLE). After downloading and registering in the app, enable Bluetooth, power on your fitness tracker, and scan for the device in the app. Once connected, FlagFit automatically syncs health data — steps, distance, calories, sleep stages, heart rate, and blood pressure — from your wrist to your phone. Data is displayed in daily summaries with charts and trend analysis.
The app also acts as a notification relay: incoming calls, SMS, and social media alerts are forwarded to your smart band so you can stay informed without checking your phone constantly.
Health & Fitness Tracking
Step Counting & Daily Activity
FlagFit records your daily step count, walking distance, and calories burned, tracking progress against personalized goals. An exercise timeline shows when and how much activity occurred throughout the day, and historical data lets you review weekly and monthly trends.
Sleep Monitoring
The app provides by recording total sleep duration and breaking it into . Daily sleep reports help you understand rest patterns and improve sleep hygiene. Wear your band to bed and keep Bluetooth connected for best accuracy.
FlagFit is a free companion app developed by Shenzhen Ultra Easy Technology Co., Ltd. (UTE) for Bluetooth Low Energy (BLE) fitness trackers and smart bands. After pairing your smart band via Bluetooth, the app serves as your health dashboard — displaying step counts, walking distance, calories burned, sleep analysis (deep/light/awake stages), heart rate data, and blood pressure estimates. It also forwards call, SMS, and social media notifications to your band, supports GPS trajectory tracking for outdoor workouts, and includes silent alarms and sedentary reminders. Free on both Android (500K+ downloads) and iOS.
How do I connect FlagFit to my smart band?
To connect FlagFit: (1) Download the app from Google Play (com.yc.flagfit) or Apple App Store (ID: 1106428739); (2) Open the app and register an account; (3) Enable Bluetooth on your phone; (4) Power on your smart band; (5) In the app, go to device settings and scan for your band; (6) Select your device from the list and confirm pairing; (7) Grant notification access when prompted. The app will then sync health data and forward notifications automatically. Keep your phone and band within 1-2 meters during initial pairing.
Why is FlagFit not connecting to my smart band?
Common FlagFit connection fixes: (1) Bluetooth off — enable Bluetooth and force-close then reopen the app; (2) Out of range — keep phone and band within 1-2 meters during pairing; (3) Cache issue — go to Settings > Apps > FlagFit > Storage, clear cache and data, then relaunch; (4) Already paired — remove the band from FlagFit and from your phone's Bluetooth settings, then pair again from scratch; (5) Compatibility — ensure your band supports BLE and is FlagFit-compatible (check device manual); (6) App update — install the latest version from the Play Store or App Store; (7) Restart both devices. If 'device not compatible' error appears, your band may require a different app.
What is the difference between FlagFit and FlagFit 2.0?
FlagFit and FlagFit 2.0 are separate apps by the same developer (UTE). The original FlagFit (com.yc.flagfit) supports older UTE smart bands and has 500K+ downloads. FlagFit 2.0 (com.yc.flagfit2) is the newer version with 1M+ downloads, supporting newer devices with additional features. Check your smart band's manual or packaging to determine which app is compatible with your specific device. They are not interchangeable — each works with different hardware models.
How does FlagFit track sleep?
FlagFit monitors your sleep by analyzing movement and heart rate data from your smart band's sensors while you sleep. It records total sleep duration and breaks it into deep sleep, light sleep, and awake ('sober') stages. Daily sleep reports show your sleep quality score and patterns. For best accuracy: (1) Wear your smart band to bed; (2) Keep Bluetooth connected; (3) Ensure the band fits snugly on your wrist. Note that sleep tracking accuracy varies by device model and wearing position.
How do I set the time on my FlagFit smart band?
Your FlagFit smart band automatically syncs time from your phone when connected via the FlagFit app. To update the time: (1) Open the FlagFit app; (2) Ensure your smart band is connected via Bluetooth; (3) The time will sync automatically. If the time is incorrect, try disconnecting and reconnecting the band. You cannot set the time directly on the band without the app — it always derives its time from the paired phone.
Is FlagFit free?
Yes, FlagFit 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 — step tracking, sleep monitoring, heart rate and blood pressure monitoring, GPS workout tracking, call and message notifications, silent alarms, sedentary reminders, and device management — are available at no cost.
How do I charge my FlagFit smart band?
Most FlagFit-compatible smart bands use a USB charging clip or magnetic charging cable. Common charging methods: (1) Detach the band module from the strap; (2) Insert the USB end directly into a USB port or use the included charging cable; (3) A charging indicator will appear on the band's screen; (4) Full charge typically takes 1-2 hours. Check your specific band's manual for exact charging instructions, as different models may have different charging mechanisms.
Does FlagFit work with Google Fit or Apple Health?
FlagFit supports data sharing with Apple HealthKit on iOS devices, allowing your step count and activity data to appear alongside other health apps. However, FlagFit does not natively sync with Google Fit on Android. Some users have reported using third-party sync tools as a workaround, but direct Google Fit integration is not an official feature.
How accurate is FlagFit health data?
FlagFit health data (steps, heart rate, sleep, blood pressure) uses sensors in your smart band to provide consumer-grade wellness readings. Step counting is generally reliable for daily activity trends. Heart rate and blood pressure readings use optical sensors and should be treated as estimates — they are not medical-grade measurements. Sleep tracking accuracy depends on device model and wearing position. For medical concerns, always consult a healthcare professional and use certified medical devices.

App crashes since last update; newest update fixed the crash issue. Thanks! Works well with my fitness band now. Sync is reliable and step counting seems accurate enough for daily use.
App Store
Fixed! Thanks for fixing the crashing issue with 2.0.1. Glad to be able to sync my device again. Sleep tracking works well and the interface is clean enough.
App Store
I love everything about this except the fact that it doesn't track my sleep consistently and doesn't always monitor the heart rate. Basic step tracking is solid though.
App Store
Bug fixed. Fantastic support, bug fixed quickly. The app pairs easily with my smart band and the daily activity summary is helpful for tracking my fitness goals.
Google Play
Good basic fitness tracker app. Steps are counted accurately and the sleep data breakdown into deep and light sleep is useful. Bluetooth connection is stable most of the time. Would like more watch face options but overall it does what it needs to.
Google Play
FlagFit works for basic tracking — steps, sleep, and heart rate are all functional. The blood pressure feature is interesting but I wouldn't rely on it medically. App sometimes needs a manual sync to pull data. Decent for a free app.
Google Play
Great companion app for my DB02 smart band. Easy setup, reliable Bluetooth pairing. All health tracking features work — steps, heart rate, sleep analysis. The GPS tracking maps my walking routes accurately. Call notifications come through instantly. Highly recommended for budget fitness bands.
Google Play
Simple and effective fitness app. I use it mainly for step counting and sleep tracking, both work well. The alarm feature with vibration is great for waking up without noise. Interface could look more modern but functionality is solid.
Google Play
The app does its job for basic fitness tracking. Pairing was straightforward with my smart band. Step counting is accurate and sedentary reminders are helpful. Wish the historical data charts were more detailed. Good enough for a free companion app.
