Frequently Asked Questions:

  • Do I need a heart rate strap with the A300?
  • If you want to see your heart rate during your workout and make sure you’re training in the right heart rate zone, then yes. You don’t need the strap to track everyday activity like steps taken, calories burned, or your sleep. Note that wearing a compatible heart rate strap during your workouts will give you a more accurate number in terms of calories burned.

  • Will I get notification when the battery is low?
  • Yes, the A300 will alert you, and then you just simply recharge it using the included recharging cable. You’ll only need to recharge it approximately once a month.

  • Which heart rate straps are compatible?
  • The A300 will connect to Bluetooth Smart straps, like The Polar H6 and H7. If you don’t already own a compatible strap, we recommend purchasing our bundle for the best price.

  • When do I actually need to wear a heart rate strap?
  • Just during your workout, so you can track your heart rate, make sure you’re training in the best zone, take advantage of the many Training Benefit features like aerobic fitness monitoring, and get the most accurate number for calories burned.

  • Can I wear this in the water?
  • Yes – it was actually designed so you can swim with it on and track your activity. To get your heart rate while swimming, pair it with the Polar H7 strap.

  • Does this watch have smartphone notifications?
  • No. If that’s feature is important to you, we recommend checking out the A360.

  • Where do I see my calories burned?
  • This number will reflect in your workout summary and in the activity menu display.

  • How accurate is the calories burned number?
  • OwnCal is the most accurate calorie counter on the market, using an algorithm based on your weight, height, age, gender, your individual maximum heart rate (HRmax) and how intensely you’re exercising.

  • Does it only track calories burned during my workout?
  • The A300 actually tracks the calories you’re burning throughout the entire day, using your basil metabolic rate (the calories your body needs to function without any movement), plus calories burned through your daily activity and any workouts you complete.
