Push performance to a whole new level.

SPORTS APPS

You can use preloaded activity profiles for trail running, swimming, biking, hiking, rowing, skiing, golfing, and more.

FITNESS AGE

This feature uses chronological age, weekly vigorous activity, and resting heart rate to estimate whether your body is younger or older than you are. You can also get tips to lower your fitness age.

RECOVERY TIME

Recovery time after each workout tells you when you’ll be ready for another hard workout. It even accounts for training intensity and factors such as stress, daily activity, and sleep.

TRAINING STATUS

This metric evaluates your recent exercise history and performance indicators to determine whether you’re training productively, peaking, or overreaching.

DAILY SUGGESTED WORKOUTS

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

ALL-DAY RESPIRATION

Track how you’re breathing throughout the day, during sleep, and during breathwork.

Tune in to your body and mind.

SLEEP SCORE AND ADVANCED SLEEP MONITORING

Get a full breakdown of your light, deep, and REM sleep stages. View it on a dedicated widget that includes your sleep score and insights.

INTENSITY MINUTES

With improvements based on guidance from the CDC and WHO, now you can understand when you’ve earned daily intensity minutes and during what activity.

BODY BATTERY ENERGY MONITORING

Track your body’s energy levels to find the best times for activity and rest.

HYDRATION TRACKING

Log daily fluid intake as a reminder to stay hydrated. When auto goal is enabled, you’ll even see estimated sweat loss after an activity, and your goal will adjust accordingly.

WOMEN’S HEALTH TRACKING

Use the Garmin Connect app to track your menstrual cycle or pregnancy. Log symptoms, get exercise and nutrition education, and more.

WRIST-BASED HEART RATE

The watch constantly samples your heart rate and will alert you if it stays too high or too low while you’re at rest. It also helps gauge how hard you work during activities — even while swimming.

Designed for both your worlds.
