XOfit is a free Bluetooth smartwatch companion app developed by Shenzhen United Power Technology Co., Ltd. Available on both iOS and Android, XOfit pairs with compatible budget smart bands and smartwatches via Bluetooth Low Energy (BLE) to deliver daily health insights — including step counting, sleep monitoring, heart rate tracking, and calorie estimates.
With over 500,000 downloads on Google Play, XOfit serves as the primary companion app for a wide range of affordable BLE smartwatches and fitness bands, offering an accessible entry point into health and activity tracking.
How XOfit Works
XOfit connects to your smartwatch or fitness band via Bluetooth Low Energy (BLE). Once paired, the app syncs health data in real time — steps, sleep stages, heart rate readings, and calorie calculations — from your wrist to your smartphone. All data is presented in clean daily, weekly, and monthly dashboards for easy trend monitoring.
The app also supports smart notifications, forwarding incoming calls, SMS, and app alerts directly to your wrist, so you never miss an important message.
Before pairing: Your Android phone must run Android 5.0 or later and support BLE. On iOS, XOfit requires iOS 12.0 or later. Make sure Bluetooth and Location services are enabled on your phone for reliable device scanning.
Step Tracking & Daily Activity
XOfit's core feature is its pedometer function, which records your daily steps and automatically calculates:
- Calories burned based on your step count, weight, and stride length
- Distance traveled in your chosen unit (km/miles)
- Exercise timeline showing your activity distribution throughout the day
You can review your daily, weekly, and monthly step history through the in-app dashboard and set personal daily step goals to track your progress over time.
Sleep Monitoring & Analysis
The XOfit app provides sleep quality analysis by tracking when you fall asleep and wake up, and breaking down your night into:
- Deep sleep — restorative slow-wave sleep phases
- Light sleep — transitional and REM-adjacent phases
- Awake periods — times when movement was detected during the night
The sleep data is presented as a timeline chart, helping you identify patterns and understand your rest quality. Combined with sedentary reminders, XOfit helps you build healthier daily routines.
Heart Rate & Blood Pressure Monitoring
On compatible smart bands with optical sensors, XOfit displays real-time heart rate readings and blood pressure estimates. These readings are for general wellness reference only — they are not medical-grade measurements and should not be used for diagnosis or treatment.
Important disclaimer: XOfit smart bands are explicitly not medical devices. All measurement data is approximate and intended for personal reference only. Always consult a healthcare professional for medical advice.
Smart Notifications & Lifestyle Features
XOfit supports sending call and message notifications from your phone to your band, so you can see who's calling or receive SMS/app alerts without checking your phone. Additional lifestyle features include:
- Sedentary reminders — vibration alerts when you've been inactive too long
- Smart alarm clock — gentle wrist vibration to wake you without disturbing others
- Remote camera shutter — shake your wrist or tap the band to trigger your phone's camera
- Weather display — current weather conditions shown directly on the watch face
- Find phone / Find device — mutual search between your band and phone to prevent loss
Watch Face Customization
One of XOfit's popular features is its watch face store, where users can browse and download a variety of dial designs for their smartwatch. The app supports:
- Pre-installed watch faces with different styles and layouts
- DIY watch face creation — customize the dial with your own photos and preferred data widgets
- A "DIY mall" section for discovering additional designs
Tip: Downloaded watch faces can be found in the "My Dials" section. If you can't find a previously downloaded face, check the DIY mall where additional designs are cataloged.
