Measure Your Heart Rate

The Galaxy Fit3 uses an advanced optical heart rate sensor to deliver real-time readings.

To measure manually: Open the Heart Rate widget → remain still → wait for the sensor to complete the scan.

For automatic monitoring, go to Samsung Health → Settings → Continuous Measurement. You can adjust intervals or enable alerts when your heart rate exceeds your set limit.

Keep the band snug but comfortable on your wrist for accurate readings.

Regular monitoring helps identify stress, fatigue, or overexertion during workouts. The Fit3 also records resting heart rate and recovery time, which are key indicators of cardiovascular health.

Avoid using the sensor in bright sunlight or moving water, as these can interfere with accuracy. Clean the rear sensor regularly with a soft cloth.
