Product Description

Polar A370 is a sleek and sporty water resistant fitness tracker that helps you stay on the pulse 24/7 with continuous heart rate monitoring, advanced sleep tracking and Polar’s unique workout features.

Find the balance: be active, have a rest and enjoy.

Get to know your heart
Learn how your heart behaves in the twists and turns of your everyday life. Polar A370’s wrist-based heart rate monitor tracks your heart rate 24/7, so you’ll get a complete overview of your daily activity. Polar A370 shows you how many calories you’ve burned, reveals your lowest and highest heart rate and shows you how your heart rate varies during the day.

When you’re working out, Polar A370’s heart rate guidance helps you train at the right intensity and drives you towards your fitness goals.

Sleep tight with Polar Sleep Plus™
Sleeping well is vitally important to your health and well-being. Polar’s new advanced Sleep Plus sleep analysis makes you an expert on your own sleep and helps you towards a more balanced lifestyle.

Sleep Plus gives you valuable insights to your sleep. It tracks the timing, amount and quality of your sleep and automatically detects when your sleep is interrupted. You can set your preferred sleep time and rate your sleep, and you’ll get sleep feedback. Learn about your sleeping patterns and think about what you can do to make the most of your night.

Get connected

Polar A370 is BFFs with your phone.
When you train outdoors, Polar A370 uses your phone’s GPS signal to track your pace and distance and to map out your route.

Polar A370’s smart notifications keep you in the loop even when you don’t have the time to check your phone. You get notifications for incoming calls, messages, social media and calendar appointments right on the screen of your Polar A370.

Keep on the move
Polar A370 is your ultimate training buddy. It makes your workouts easy and convenient with wrist-based heart rate tracking and helps you train at the right intensity with heart rate zones. Polar’s unique and scientifically validated Smart Coaching features guide you through your workouts and give you motivating feedback.

An active lifestyle is about healthy choices outside the gym as well. Polar A370 keeps you on the move in your everyday life — it gives you a daily activity goal and reminds you to get up and move if you stay still for too long.

Can I pair my cycle computer with a smartphone, power meter and other devices? 

You will need a wireless computer to sync with other devices. Most wireless computers sync using 2 wireless technologies – ANT+ & Bluetooth Smart.

ANT+

ANT+ enabled devices to talk to each other and present the information on a compatible device.

Bluetooth Smart

Bluetooth Smart is a low energy wireless technology designed for smart sport and fitness. The long battery life in sensors makes it ideal for regular use in cycling. 

Always check your smartphone’s OS and 3rd party devices are compatible.

Would a Watch / Fitness band be better for me?

If you’re looking for something more versatile then cycle watches are a great alternative. You can still gather data from cycling sensors, but you can also gather data for different sports too. They are great for triathletes and those that do multiple sports. 

You can easily transfer data from a road bike to a mountain bike, from running to swimming. There aren’t many outdoor exercises you can’t track.

What software & Apps should I use?

Strava

Strava is perhaps the most well-known cycling App / software around. All you need is to record your cycling with a compatible GPS device, upload it to Strava and then you can analyse your data. You can compare your performance to previous efforts, your mates and even pro riders - all of this, for free.

Garmin Connect

All Garmin computers and devices will work with Garmin Connect. This is an online service that allows you to analyse your performance data, and share it with your friends. Reports show you how you’re progressing and you can use the calendar feature to plan your training sessions over time.
