It's widely known that physical activity is a major factor in maintaining health. In addition to being physically active, it's important to avoid prolonged sitting. Sitting for long periods of time is bad for your health, even on those days when you train and gain enough daily activity. Your M400 spots if you’re being inactive for too long during your day and this way helps you to break up your sitting to avoid the negative effects it has on your health.

If you’ve been still for almost an hour, you'll get an inactivity alert - It's time to move is shown. Stand up and find your own way to be active. Take a short walk, stretch, or do some other light activity. The message goes away when you start moving or press any button. If you don't get active in five minutes, you'll get an inactivity stamp, which you can see on the Flow app and Flow web service after syncing.

You can set the alert on or off in Settings > General Settings > Inactivity alert.

The Flow app gives the same notification if it has a Bluetooth connection to your M400.

Both the Polar Flow app and the Polar Flow web service will show you how many inactivity stamps you have received. This way you can check back on your daily routine and make changes toward a more active life.

Sleep information at Flow web service and Flow app

M400 will track your sleep time and quality (restful or restless), if you wear it at night. You don't have to turn the sleep mode on, the device automatically detects from your wrist movements that you're sleeping. Sleep time, and its quality (restful or restless) is shown at the Flow web service and Flow app after M400 is synced.

Your sleep time is the longest continuous rest time that takes place within 24 hours starting from 18:00/6pm to next day’s 18:00/6pm. Breaks shorter than one hour in your sleep don't stop sleep tracking, but they are not taken into account in the sleep time. Breaks longer than one hour stop sleep time tracking.

The periods when you sleep peacefully and don’t move a lot are calculated as restful sleep. The periods when you move and change your position are calculated as restless sleep. Instead of simply summing up all the immobile periods, the algorithm gives more weight to long than short immobile periods. The percentage of rest- ful sleep compares the time you slept restfully with the total sleeping time. Restful sleep is highly individual and should be interpreted together with sleep time.

Knowing the amount of restful and restless sleep gives you a look into how you sleep at night and if it’s affected by any changes in your daily life. This may help you in finding ways to improve your sleep and feel well rested during the day.

Activity data in Flow App and Flow web service

With the Polar Flow mobile app you can follow and analyze your activity data on the go and have your data synced wirelessly from your M400 to the Polar Flow service. The Flow web service gives you the most detailed insight into your activity information.
