Polar’s latest fitness tracker is the A370, and like the company’s other wearables, it’s capable of fitness tracking, heart rate monitoring, and sleep tracking. In an upgrade from the previous model A360, which only took heart rate readings during active exercise, the A370 continuously senses your heart rate every five minutes.

And... that’s basically the update. Otherwise, it’s a pretty well-rounded fitness band — it can track workouts, inform you of notifications from your connected phone, and hook up to Polar’s other fitness accessories like standalone heart rate bands and scales to loop in additional information into your fitness routine.

The A370 is available for preorder now for $179, $20 cheaper than the old A360.
