How GFit Pro Works
The GFit Pro app pairs with your compatible smartwatch via Bluetooth Low Energy (BLE). Once connected, health data syncs automatically — heart rate, blood oxygen, steps, calories, distance, and sleep stages flow from your wrist to your phone. The app displays your health data in clear daily charts and trend views.
GFit Pro also acts as a device management center: customize watch faces, set alarms, configure sedentary reminders, enable do-not-disturb mode, and manage drink water reminders — all from your phone.
Health & Fitness Tracking
Heart Rate Monitoring
GFit Pro provides real-time heart rate monitoring through your connected smartwatch. View continuous heart rate data, track trends throughout the day, and review historical heart rate charts to understand your cardiovascular health patterns.
Blood Oxygen (SpO2) Monitoring
Monitor your blood oxygen saturation (SpO2) levels directly from your wrist. GFit Pro displays SpO2 readings synced from your smartwatch, helping you stay aware of your oxygen levels during daily activities and sleep.
