WRIST-BASED HEART RATE

Optical heart rate technology gauges activity intensity as well as heart rate variability to calculate your stress level. It also tracks underwater without a heart rate strap.

PULSE OX SENSOR

For altitude acclimation, sleep monitoring or between Apnea/Apnea Hunt activities on the surface, a Pulse Ox sensor uses light beams at your wrist to gauge how well your body is absorbing oxygen.

ALL DAY RESPIRATION

Track how you’re breathing throughout the day, during sleep and during breathwork and activities such as yoga.

ADVANCED SLEEP MONITORING

Get a full breakdown of your light, deep and REM sleep stages as well as Pulse Ox and respiration data. View it all on a dedicated widget that includes your sleep score and other insights.

RECOVERY TIME

After each workout, recovery time lets you know when you’ll be ready for another hard workout. It even accounts for training intensity and factors such as stress, daily activity and sleep.

DAILY WORKOUT SUGGESTIONS

For training guidance that takes you and your fitness level into account, get daily run and ride recommendations based on your current training load and training status.
