Polar A360 Fitness Tracker & HR Monitor Review

hr tracker

Finland-based Polar has been a household name in the health monitoring industry for more than 3 decades, and their decision to launch a wearable tracking device is one of their best so far. With the Polar A360, they made the world of wearable tech much more colorful and competitive.

The Polar A360 is the company’s very first (and successful) attempt to combine all the best functionalities and features of an activity tracker, sports watch and heart rate monitor into one small wearable device.

My verdict: This activity tracker offers superior daily activity tracking, plus advanced training metrics complete with notifications. The display shows smartphone and call alerts, as well as workout data. While it has no GPS (a bummer for cyclists and runners), it presents a wide array of fitness activity session information directly loaded to the Polar flow app.

If you want to compare this tracker to other leading models, head over to our full Buyer’s Guide where you will find tons of information, as well as our favorite models for this year.

Overview & Features

The Polar A360 is waterproof, and is the very first to feature a wrist-based heart rate monitor. It also includes a personalized training guidance tech from Polar, plus a 24/7 activity tracker. We totally liked how the product included smartwatch features and a yummy colored touchscreen.

You can’t expect a fitness band to look different, but the A360 has a colorful and bright touchscreen, reminiscent of the Samsung Gear Fit or even the Microsoft Band. The A360 screen is not as ergonomic as its competitors, though, because the screen is not curved.

Polar A360 Fitness Tracker & HR Monitor

Product Rating: (4.5/5)

  • Great price to value ratio
  • Good display
  • Entirely waterproof
  • Provides you with tons of information
  • Can track your sleep quality
  • Has a calorie burner calculator
  • Heart-rate sensor is accurate

Materials, Durability, and Water Resisntace

The band is made of a soft silicone material, and comes in three sizes—small, medium and large—and five band colors—lime green, black, blue, white and pink. It is interchangeable, and a real comfort on the wrist. The tracker can be popped out of its strap and be used with a new one.

The A360 is water-resistant up to 100 feet, so you won’t have to take it off when you shower or during pool activities. It’s not as waterproofed compared to Nike’s +Fuelband SE, but it’s still highly water-resistant.

Battery Life

The battery life is more than decent, lasting up to 12 days on a single charge, with notifications disabled. Because it does not have GPS, the battery life is doubled compared to its competitors, even with 1 hour daily training and 24/7 activity tracking.


The display is ultra-sharp with its full-colored TFT display, which can be considered as both a pro and a con, considering the fact that colored displays are more sensitive to sweat and moisture.  But with the A360’s water-resistant feature, the unit can be safe from quirky displays caused by sweat drips and rain.

That display might feel a little date going into 2020 since most models now come with a LED one which is sharper and more crisp but it still gets the job done.



The A360 provides in-depth feedback of all your activities, including sleeping patterns, calories burnt, steps, stairs climbed, and distance traveled. It even reminds you to get up and move when you have been sitting for a long time.

One of the best A360 features is the Polar proprietary optical heart rate sensor. Paired with the Polar Coach feature, you can take advantage of its real-time monitoring, which helps you get maximize your cardiovascular workouts without having to use additional devices.

Polar stated that the A360 sensor is fully made using their own algorithms, and the unit boasts of a single photodiode and two green LEDs. While this configuration is common among optically-sensored products in the market, it is not common in sports-tracking wearable tech.

While the A360 comes with Polar’s very own algorithm to ensure accuracy, you can still use Polar’s chest strap H7 heart-rate monitor, which you can connect to the A360 via Bluetooth. You can also sync your device with other apps such as MyFitnessPal, Google Fit, MapMyFitness and Apple Health Kit.

Note: the Polar A360 does NOT track heart rate 24 hours a day. It only tracks your heart rate when you enable the heart rate sensor during workout periods.

Other Things We Liked about the A360

While it can do better with its waterproof technology, being water resistant up to 30 m (100ft) is not that bad. This means you won’t have to worry about ruining it when you wear it in the shower, or when you go for a swim in the pool or ocean.

Note: Polar reminds users that the charging port should be totally dry before plugging it in for charging or syncing.

You can customize the home display screen, with 4 designs to choose from, which isn’t bad but we wished there was a little more customization available to the user.

Now, let’s take a look at some of the main pros and cons of this fitness tracker…

Conclusion and Rating

Product Rating: (4.5/5)

The Polar A360 is bound to the Polar Flow management system, which means that all your daily activities, calories, steps, sleep and workout can be synced to the Polar web and mobile app. With this functionality, you can analyze your daily output and workout data.

You can opt into another nice functionality—Polar Flow for Coach—which allows you to receive feedback on your workout, as well as info on new training routines. You can even use this functionality to share your live heart-rate data.

Being smartwatch-capable, the A360 can display notifications from your Bluetooth-paired smartphone. Thus, your messages, calendar alerts, and even calls can show up on the display.

The Polar A360 is a few notches up the low-end Polar Loop 2, amalgamated with Polar’s popular proprietary optical heart sensor. While it is not GPS enabled, there’s a huge possibility that Polar will release a waterproof fitness activity tracker with this feature soon.
