Fitbit Charge 5 – Steel Blue FB421SRBU-FRCJK
Fitbit Charge 5 + Premium connects the dots between your activity, sleep and stress so you can make the best decisions for your body, mind and health. It all starts with your 6-month Premium membership* and Daily Readiness*, a score based on activity, sleep and heart rate variability (HRV) that helps you optimise your workout routine. Your score comes with personalised activity recommendations: low means go easy and recover—light yoga, deep breathing—while a high score gives you the green light to go all out. Enhance your recovery routine with advanced stress-management tools like the on-wrist EDA sensor. Stay ahead of heart health with atrial fibrillation (AFib) heart rhythm assessments using the on-wrist ECG app.* And you’ll always have motivation to reach new goals with hundreds of guided workouts, a gallery of refreshing mindfulness sessions plus the fitness features you know and love like Active Zone Minutes and built-in GPS.
Daily Readiness Score
Taking time to recover can produce better results than working out hard all the time. Understand what’s best for your body with the Daily Readiness Score on Fitbit Premium. Each morning, you’ll get a score in the Fitbit app based on your activity, sleep and heart rate variability. You’ll also get a personalised goal for the day, plus recommended workouts or recovery sessions, depending on what your body needs that day. As you get more fit over time, your scores and daily goals adapt with you.
Stress Management Score
Get a daily score showing your body’s physical response to stress. You can see how your exercise routine, mindfulness practice and sleep help to manage your stress levels.
Take steps to improve your stress levels with an on-wrist EDA sensor mindfulness session. The app detects electrodermal activity — tiny changes in your skin’s sweat level which may indicate your body’s response to stress.
Fitbit ECG (Electrocardiogram) App
Keep track of your heart health with a compatible ECG app that assesses your heart for atrial fibrillation—a heart rhythm irregularity—and share the results with your doctor.
High & low heart rate notifications
Your heart rate is a key indicator of health, so stay informed when Charge 5 detects that your heart rate is above or below your threshold.
See your real-time pace & distance without your phone using built-in GPS during outdoor runs, rides, hikes and more, then see a map of your workout route in the Fitbit app. If you have your phone nearby, Charge 5 connects to your phone’s GPS to help extend your tracker’s battery.
6-Month premium membership
Charge 5 unlocks a 6-month membership complete with personalised insights, advanced analytics, guided programs, mindfulness & sleep tools, workouts and more.
Workout intensity map
After outdoor exercise with GPS, check your workout intensity map in the Fitbit app to see your pace and heart rate zones throughout your route and learn where you put in the most effort.
24/7 Heart rate tracking with PurePulse
Track calorie burn and optimise workouts with PurePulse continuous heart rate tracking, then see your resting heart rate trends and cardio fitness level (VO2 Max) in the Fitbit app.
Active zone minutes
Get the results you want from every workout. Active Zone Minutes uses your heart rate to guide you toward your desired intensity level—then helps keep you there.
Cardio fitness level
Get to know your VO2 max — a measurement of how well your body uses oxygen when you’re working your hardest. Keep tabs on your score to see how you improve over time.
Oxygen saturation (SpO2) monitoring
Track SpO2 — the level of oxygen in your blood — to help you learn when there may be an indication of important changes in your overall wellness.
Skin temperature tracking
Stay informed and in tune with your body using Charge 5’s nightly skin temperature tracking. When your temperature varies from your baseline in your Health Metrics dashboard, you’ll be more aware of potential signs of changes in your body. Your sleep patterns, menstrual cycle, the room temperature, potential onset of fever or even your bedding can cause changes.
Health Metrics dashboard
Track SpO2—the level of oxygen in your blood—plus heart rate variability, skin temperature variation and more.
20 Exercise modes
Set personal goals for runs, rides, strength training and more, then get real-time stats to help you keep the pace or maintain your target heart rate zone.
Forget to start tracking? No problem. SmartTrack automatically recognises and records workouts like elliptical, runs, swims and more.
Timer & stopwatch
Get instant access to tools that make your life easier — like a timer for interval training and a stopwatch for tracking sets at the gym.
All-day activity tracking
Charge 5 tracks all-day activity like steps, distance, Active Zone Minutes and calories burned to show how every part of your day gets you closer to your goals.
Health & wellness reminders
Activate optional personalised reminders for beneficial tasks that can be tough to remember, like staying hydrated, sticking to a sleep schedule, getting in activity and more.
