Building Your Biological Clock
Your vital baseline and training data combine to build a complete, personalized sleep and recovery system.
True Sleep Calibration
The watch combines pure sensor data with your daily subjective feedback on mood and physical condition. This ensures your tracked sleep perfectly matches your lived experience and actual morning readiness.
Training Load Sensitive Sleep Goals
Static 8-hour recommendations are replaced with dynamic targets. The system calculates the exact amount of sleep you need to recover by automatically adding required sleep time based on your previous day's physical training load and any accumulated sleep debt.

The watch evaluates your sleep timing against a rolling baseline of your personal patterns. By treating every day of the week equally, it guides you toward a steady circadian rhythm and eliminates hidden disruptions like social jetlag.
Smart Recovery Alarm
Using continuous sleep stage detection, the system identifies your optimal wake window and wakes you at the precise moment your body is recovered and ready to start the day.
