2. How does XERAFIT measure recovery?
XERAFIT looks at signals such as your heart rate, HRV, sleep and recent activity to give you insight into how recovered your body is. Instead of focusing on a single measurement, it helps you understand patterns over time and how training, sleep and everyday habits affect your recovery.
3. How does XERAFIT track my sleep?
Simply wear XERAFIT to bed. While you sleep, the band monitors your body and movement to provide insights into your total sleep and sleep stages, including REM and deep sleep. XERAFIT AI then helps turn that data into easy-to-understand insights about your night.

XERAFIT should sit comfortably and securely against your wrist without being excessively tight. Good skin contact is important because the optical sensors rely on consistent contact to provide reliable measurements.
1. What is HRV and why does XERAFIT track it?
Heart Rate Variability (HRV) measures the variation in time between individual heartbeats. Tracking how your HRV changes over time can provide useful context about recovery, stress and how your body is responding to training and everyday life.
2. How does XERAFIT track my sleep?
Wear XERAFIT while you sleep and it uses your overnight signals and movement to estimate your sleep duration and sleep stages. This helps you see not only how long you slept, but how your sleep patterns change over time.
3. How does the Recovery Score work?
XERAFIT combines signals such as sleep, heart rate, HRV and activity to provide a simple recovery insight. Rather than focusing on a single reading, recovery becomes more useful as XERAFIT learns your personal baseline and tracks changes over time.
4. What does blood oxygen (SpO₂) tell me?
SpO₂ is an estimate of the percentage of oxygen carried by your blood. XERAFIT tracks SpO₂ as another signal that can help you understand your body's patterns. XERAFIT is a wellness device and should not be used to diagnose or monitor medical conditions.
5. What does XERAFIT AI do with my data?
XERAFIT AI turns your collected data into easier-to-understand insights. Instead of simply presenting numbers, it helps explain patterns across areas such as sleep, activity and recovery, giving you useful context about how your body is responding over time.
