SPORTS APPS
Use preloaded activity profiles for trail running, swimming, running, biking, hiking, rowing, skiing, golfing and more.
FITNESS AGE
This feature uses chronological age, your weekly vigorous activity and resting heart rate to estimate if your body is younger or older than you are. And you can get tips to lower your fitness age.
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.
TRAINING STATUS
This metric evaluates your recent exercise history and performance indicators to let you know if 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 all 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 so you can 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 rate5 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.
