Fitbit Sense 2 Smartwatch

Learn to manage stress and sleep better with our most advanced health and fitness smartwatch.

Understand stress, then minimise its effects
Better sleep. Improved mood. More energy. Managing stress with Sense 2 can help you get there. Identify patterns of stress with all-day body-response tracking and smart notifications to remind you to reflect on your emotions. Try new ways of managing stress with guided breathing, exercise, meditation and more.

Better understand sleep through science
Sense 2 helps you get the sleep of your dreams. Sleep Profile breaks down your sleep data each month and pinpoints how you can improve your sleep based on 10 key sleep metrics. Check your Sleep Score to learn about the quality of your previous night's sleep, and get a breakdown of time in light, deep & REM sleep with Premium.

Tune in to your body
Sense 2 helps illuminate changes in your wellness. Check your Health Metrics dashboard to see heart rate variability, skin temperature variation, SpO2 and more. You can also use 90 days of health trends to uncover changes to your well-being.

Everything starts with heart
Use the ECG app for on-demand atrial fibrillation assessment or turn on irregular heart rhythm notifications to assess your heart while you're still or sleeping. Heart-rate tracking surfaces insights from your sleep, stress, activity and more while high & low heart rate notifications keep a close eye on your heart rate.

Work out smarter
Do what you love, just get more out of it. Daily Readiness Score shows what level of workout your body is ready for, including an Active Zone Minutes goal and Premium workout recommendation. Track 40+ exercise modes and use built-in GPS◆ for real-time pace and distance—even in up to 50 metres of water

- Stores heart rate data at one-second intervals during exercise tracking and at five-second intervals all other times

Water Resistance

Water-resistant to 50m. After getting the band wet, we recommend drying the band because, as with any wearable device, it's best for your skin if the band is clean and dry.

Care

Give your wrist a rest by taking the band off every now and then. If the band gets wet or you sweat in it, remove and completely dry the band before putting it back on. Learn more.
