Active Zone Minutes
Fitbit has created a new metric: Active Zone Minutes (AZM) to help you work out smarter, as a minute of walking and a minute of running don't provide the same benefits. By using your personalised HR zones to alert and reward you for higher intensity movement, Fitbit makes it easy for you to hit your health targets.
Enable Fitbit Charge 4ƒ??s Smart Wake feature and this handy device will find the best time to wake you up (based on your optimal sleep stage), starting 30 minutes before the alarm time that you set. Don't worry, if this feature isn't activated your alarm will go off as per the set time.
Fitbit Charge 4 can track your light, deep and REM sleep and then provide insights about your slumber.
Thanks to built-in HR monitoring, Fitbit Charge 4 can help you better understand your sleep quality each night, based on your heart rate, time asleep and restlessness.
The Fitbit Charge 4 is water-resistant to 50 metres. This device can be worn in the pool or shower, however please don't take it into the sauna or soak in the bath with it on.
