Start Using Your Device

Once your Fit3 is connected, you can begin exploring its many features. The interface is designed around intuitive gestures:

• Swipe left/right to move between widgets (Steps, Heart Rate, Stress, Sleep, etc.).
• Swipe down for the quick panel (Brightness, Do Not Disturb, Battery).
• Swipe up to access your app list.
• Press and hold the side button to launch assigned shortcuts (like starting a workout).

To track workouts, open the Exercise app. Choose from walking, running, cycling, or other supported activities. The tracker automatically detects workouts and pauses when you stop moving.

For health monitoring, use Samsung Health to view detailed metrics like calories burned, floors climbed, and total active minutes.

Notifications from your smartphone appear on the watch instantly — you can read messages, reject calls, or respond using preset replies.

Battery management is efficient, with power-saving modes that disable continuous heart rate monitoring or screen wake-on-lift to extend runtime.

The Fit3 also supports sleep tracking, analyzing your sleep stages and offering personalized insights to improve rest quality.
