You and the A300. Designed for movement and perfectly coordinated. Get fit the right way and quickly, to look good and feel great. Move. A small change can make a big difference. You can choose from easily interchangeable, colorful bands to match your mood and style. The durable silicone band of the water-resistant A300 is lightweight and comfortable to wear.
Every step, jump, and distance counts. The A300 tracks your steps, distance, and calories burned, motivating you to reach your activity goals. If you've been inactive for too long, the A300's vibration alert reminds you to get moving.
Your well-being requires an adequate amount of restful sleep. The A300 automatically records the start of your sleep and the moment you wake up, gently waking you with a vibration. Track your sleep patterns in Polar Flow to find the right balance between training, daily activity, and rest.
