To recap
If you’re looking for an affordable fitness tracking watch then the Polar has plenty to offer. It covers the basics for a range of sports, provides guidance and feedback, will track your sleep and your daily activity. But its lack of GPS means it’s just not as feature-packed as some alternatives, while we question some of the automation, delays in display feedback and overall heart rate accuracy.
