It’s important for a fitness tracker to have multiple functions because each user will have a different need for their watch. While some like to bike, others want to run or walk or swim or any other number of activities. Fitness trackers also need to be able to give valuable feedback so you can fine tune your healthy lifestyle and perform at your optimal level. Some fitness trackers come with continual monitoring, goal setting, and even sleep tracking options to help you meet these needs.

The Polar A370 does its best to keep you in the loop when it comes to your health and fitness with many of these exciting features.


The Polar A370 is the improved version of the A360 model. It has similar features, but there are a few new bells and whistles that help propel it ahead of its predecessor.

The A370 offers smart coaching that can translate into numerous types of activity, so whether you’re a runner or a swimmer, you can use this fitness tracker to help you meet your goals. The most significant new feature of this tracker is the continuous heart rate monitoring. Even if you are not exercising, the wristband will track your heart rate every five minutes and store that data for you to look at on their app. You can see when your heart rate was the lowest and when it was the highest, and this can guide your fitness routine.

You can also track your sleep with the Sleep Plus feature. The watch monitors your heart rate and sleep cycle all night long and then gives you feedback. You can also rate your sleep quality, and the program will add that to their data to provide you with a better picture of your sleep.

You can also have the Polar A370 connect with your phone via Bluetooth so you can track GPS while you’re out on a run. All the data collected, for any workout, can also be stored and sent to Polar’s app, Polar Flow, where you will get detailed information and graphs about your performance and day.

When you purchase the Polar A370, you get the watch and a micro USB connector to charge the tracker and sync data. The A370 is compatible with Apple and Android devices, Polar equipment such as the heart rate sensor or smart scale, as well as third-party fitness apps like MyFitnessPal or Google Fit.

This fitness tracker is great for just about anyone looking to improve their health and those that really like to use data to finetune their routine. The ability to send data to third-party apps is a nice touch and allows you to compile as much data on your fitness as possible. The GPS tracking through your smartphone is helpful, but it does mean you have to carry two devices with you when you run to record your information.

Concerning aesthetics, the A370 is almost exactly like the A360. There are two sizes, small and medium/large, and it comes in white or black. You can purchase additional wristbands that come in assorted colors. The clasp of the A370 watch is much easier to use than the A360 and features a traditional watch clasp. The touchscreen is rather large, so you can easily see your stats. It also turns on when you move your wrist and gives you plenty of feedback at a glance during your workouts.

Overall, the tracker is an excellent tool for you to hone your particular routine better. The review of the Polar A370 can help you go in depth with more of the unique features.

  • The cover for the USB port isn’t as secure and can easily be lost which makes it hard to keep the watch waterproof.

Overall Fitness Monitoring

polar-a370-fitness-watchOne of the best things about the Polar A370 fitness tracker is that it can do so much more than monitor your workouts. While that is a critical component of any fitness tracker, it can be helpful for your overall health to get a complete picture of your day.

The continuous heart rate monitor is significant in that you can see how your day affects your heart rate. Monitoring your heart throughout the day also gives you a more accurate calorie burn so you can see how your efforts are benefiting your goals. While the HR monitor only checks every 5 minutes throughout the day, during your workout, it is collecting data the entire time, so when you are exerting the most effort, you can get the most detailed data.

The Sleep Plus monitoring is perhaps even better than the continuous heart rate monitor. Sleep is increasingly becoming a crucial part of fitness and recovery is almost as crucial as tough workouts. If you can optimize your rest, you will be able to push yourself when you need to most. The Polar Sleep Plus automatically tracks the quality of your sleep and detects any interruptions.

You can also set sleep goals such as the amount of time you want to sleep and rate your sleep for each night. With this information, the A370 can give you insightful feedback and allow you to get the best sleep for your needs.

Finally, all the smart coaching features of this tracker really help you meet your fitness goals, whatever they might be. You can set an activity goal, and the tracker will help give you the motivation to reach that.
There are inactivity reminders that will help you get up and moving as well as show you how the little movements in your day all add up. There is also a fitness test you can take to see how your overall fitness level improves with time as well as the ability to set up a running program to get you ready for a 5k all the way up to a marathon.


One way that the A370 helps you improve your fitness is the statistics and feedback you can get. All data that your watch collects can sync with your computer and the Polar Flow app. This app compiles your data and puts it into graphs and charts so you can easily see where you are getting better and the areas that need to improve.

If you choose to use your phone during a run or walk, you can sync via Bluetooth and get even more data including maps and mileage. The Polar Flow app also allows you to analyze your workout programs and see where you can tweak certain things.

The Polar A370 also gives you the ability to sync with third-party apps, such as Google Fit or Apple Health Kit. This feature is particularly helpful for first-time fitness tracker users who might have been using these other apps to compile their data. Now they can add even more information and have more feedback on their routines and better reach their goals.

The A370 also gives you notifications and feedback all throughout your workout which helps you meet any goals you set. You can program your tracker before a workout, and the tracker will guide you through your program to keep you on target. You can save your favorite workouts so you can come back to them again and again and track your improvements.

polar-a370-reviewsPeople who had smaller wrists sometimes couldn’t get the watch to stay tight enough, and it would slip around during workouts, which was a minor annoyance.
