Inaccurate measurements (steps, calories, distance, heart rate, blood pressure, blood oxygen, etc.)Updated 2 months ago

Your watch uses optical and motion sensors, plus internal algorithms, to estimate activity and health metrics. These values are for general wellness and fitness tracking only and are not for medical use. Differences versus other devices are normal because brands use different sensors and algorithms.

Important note:

Do not compare these readings with medical equipment or unrelated devices such as smartphones, which use different methods and technologies.

Common factors that affect accuracy:

• Fit and placement: Loose, tight, or incorrect positioning of the watch.
• Skin factors: Skin tone, body hair, tattoos, or perspiration can interfere with optical sensors.
• Movement: High movement during readings (especially HR or SpO₂).
• Environment: Cold weather or low skin temperature.
• Strap adjustment: Poor sensor contact due to improper strap fit.

Improve measurement consistency:

• Wear the watch snugly (about one finger-width above the wrist bone).
• Keep the back of the watch and your skin clean and dry before readings.
• Remain still and relaxed during HR, SpO₂, or BP readings — avoid moving or talking.
• Avoid measuring immediately after workouts or while sweating or in direct sunlight.
• Keep firmware updated through the app to receive algorithm improvements.
• Consider continuous monitoring to help the watch learn your patterns over time.
• For step tracking issues, try wearing the watch on your dominant hand.

Focus on long-term trends rather than isolated numbers. These measurements are estimates intended to help you monitor changes over time, not clinical-grade diagnostics.
