Fitbit Inspire 3 Midnight Zen
Do what you love and feel your best with Inspire 3 that helps you stay on top of your stress, fitness and sleep—all you have to do is wear it. Track Health Metrics like skin temperature & blood oxygen, plus get daily scores that show how hard you can exercise today or how well you’re managing stress.
Fitness: Daily Readiness Score Premium Only: Based on your stress, sleep & activity, Daily Readiness Score tells you what your body can handle so you can dial your workout plans up or down. Because when you listen to your body, you see better results.7
24/7 Heart Rate: Watching your heart rate during exercise lets you know when you’re in fat burn, cardio or peak zones so you know how hard you’re working. The more you can comfortably push yourself, the more benefits you’ll see for your heart.
Active Zone Minutes: When you work out harder, you deserve more credit. Active Zone Minutes tracks the time you spend in your target heart rate zones, giving you double minutes when you’re in cardio or peak. We do the maths and show you if you’re hitting the recommended 150 minutes each week.
Cardio Fitness Level: Using your VO2 max—how well your body uses oxygen during exercise—Fitbit gives you a personalised score that helps you understand how fit you are.
Pace and Distance with Phone GPS: Connect to your phone’s GPS to see pace and distance on your wrist during jogs, hikes or bike rides and see a map of your effort post-workout.
20 Exercise Modes + Smarttrack: Choose from 20 exercise modes to get real-time stats like pace and calorie burn during a workout. If you forget to hit start, no sweat—SmartTrack automatically records common exercises for you.
All-Day Activity Tracking: It doesn’t matter what you’re doing—if you’re moving, it’s exercise. Inspire 3 tracks your steps, distance, calories burned & Active Zone Minutes 24/7.
Reminders to Move: Feel like you've been sitting too long? Fitbit’s got you—buzzing your wrist so you can take yourself for a walk.
Health: Always-on Wellness Tracking: The Fitbit app is like a dashboard for your body—keeping tabs on your resting heart rate, blood oxygen, skin temperature & more. By watching for changes, you can get to know your body, tweak your routine and feel your best.1
SpO2 (Blood Oxygen): This number tells you how well oxygen is distributed in your body. Fitbit makes it easy to track your blood oxygen levels so you can learn when there may be an important change in your well-being.2
Note: Feature is called “SpO2” on device, but “blood oxygen” is more approachable. Ideally try to use both to teach users they’re the same thing.
Skin Temperature: Tracking your skin temperature variation can help you spot changes that may be related to fever, menstrual cycle, activity, sleep environment & more.3
Resting Heart Rate: Resting heart rate is a general indicator of your overall fitness—the lower it is, the stronger your heart. If you see a sudden increase, consider rehydrating and resting.
High/low Heart Rate Notifications: If your heart rate goes above or below your usual range while you’re at rest, your Fitbit will send you a notification because an unusually high or low heart rate could mean something’s up.
Irregular Heart Rhythm Notifications: (In-App Name: Irregular Rhythm Notifications) Detect AFib just by wearing Inspire 3 to sleep. Share the report with your healthcare provider so they can take a closer look.
Menstrual Health Tracking: Log periods, record symptoms, estimate ovulation & find patterns in your cycle using Inspire 3 and the Fitbit app.4
Stress & Sleep: Stress Management Score: See how well your body is handling stress with this daily personalised score. A high score means you’re ready to tackle big things, while a low score is your body asking for some self-care.
Mindfulness Sessions: Learn to respond to stress in a healthier way so you feel cool, calm and in control. With relaxing mindfulness sessions from Fitbit available on your phone, you can practice your skills anywhere.5
Reflections: Not all days deserve a smile emoji—and that’s okay. Log your stress level with Fitbit so you can notice how you’re feeling and if it might be affecting other parts of your life, like sleep or energy.
Relax Breathing Sessions: The Relax app is like a mindfulness teacher on your wrist—guiding you through calming breathing sessions so you can find your happy place whenever you need to.
Sleep Profile New - Premium Only: Do you snooze deep like a bear or float in and out like a dolphin? Find out what your sleep animal is, then tweak your habits to match. Plus get a detailed analysis of your sleep each month that shows where you’re solid and where you can do better.6
Sleep Score: As a Premium member, you see what’s impacting your Sleep Score: whether you’re not sleeping long enough, or not getting enough deep or restorative sleep. Then you can figure out what changes to make, like setting a bedtime reminder on your Fitbit or doing a meditation before bed.
Smart Wake: A vibrating alarm wakes you during the optimal sleep stage so you feel refreshed and on your game.
