DAILY ACTIVITY

Every move becomes part of the picture.

X3 tracks steps, active time, distance, and estimated calories throughout your day, helping you understand how much you’re moving beyond structured workouts.

WORKOUT TRACKING

See how your heart responds to movement.

Continuous heart-rate tracking helps X3 capture changes throughout your day, giving you useful insights into activity intensity, everyday wellness, and recovery.

ACTIVITY INTENSITY

Know when you're moving - and how much.

X3 uses its built-in motion and heart-rate sensors to help distinguish periods of rest from active movement, making it easier to understand the intensity of your daily routine.

RECOVERY

Fitness doesn't stop when the workout ends.

Heart rate, HRV, sleep, and activity trends come together to provide recovery insights, helping you understand when your body may be ready for more activity or when a lighter day could make sense.
