How to Install Software Updates to My Descent G1 Series Watch

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.
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.
