Features:

Continuous heart rate

Follow your heart rate around the clock with Polar’s continuous wrist-based heart rate solution.

Continuous heart rate complements Polar’s 24/7 activity tracking. The combination of continuous heart rate measurement and 24/7 activity tracking takes into account the intensity of your activity more comprehensively – even activities with very little arm movement (such as cycling or walking with grocery bags) can be counted towards your daily activity goal and calorie burn more accurately. The heart rate graph in the Polar Flow app and web service shows how your heart rate varies during the day. You’ll also get to know your highest and lowest daytime heart rate and your lowest night-time heart rate.

Polar’s continuous heart rate solution is intelligent, dynamic and optimized to complement 24/7 activity tracking in the best possible way. Your wrist unit checks your heart rate at regular short intervals, and if it detects that your heart rate is elevated, it automatically starts to record it. When your heart rate goes down, the recording stops automatically. The automatic heart rate recording also begins when the accelerometer on your wrist unit detects a high activity level. This way, your Polar device makes sure you get credit for all those important active moments in your day.

24/7 Activity Tracking

Tracks your daily activity at five intensity levels for 24 hours a day, seven days a week, and provides a complete picture of all of your activity. It counts your active time, daily burnt calories, steps, distance from steps and sleep.

It’s based on the analyses of the frequency, intensity and regularity of your movements together with your physical information.

Intensity levels are:

  1. Resting (sleep and rest, lying down)
  2. Sitting (sitting or other passive behavior)
  3. Low (standing work, light household chores)
  4. Medium (walking and other moderate activities)
  5. High (jogging, running and other intense activities)               

You can also see how different activity intensities accumulate daily activity: the higher the intensity, the faster you’ll reach your activity goal. 

Sleep Plus

Most adults do very well with eight hours of sleep, but sleep needs may vary from person to person. It is recommended that adults get between 7 to 9 hours of sleep. Your sleep needs are affected by several factors like individual characteristics, training load, mental stress, body’s condition and possible sleep debt.

Polar Sleep Plus automatically detects the timing, amount, and quality of your sleep based on your wrist movements.

  • Sleep time shows the total time between when you fell asleep and when you woke up.
  • Actual sleep shows how much of your sleep time was actually spent asleep.
  • Interruptions show you how much time you spent awake during the night.
  • Sleep continuity tells you how continuous your sleep was on a scale of 1-5, where 5 reflects uninterrupted sleep. The lower the value the more fragmented your sleep was.

Activity Goal

The Activity Goal helps and motivates you to stay active all day long. Your device tells you your daily Activity Goal and guides you on how to reach it.
