Polar A370


The fairly priced Polar A370 isn't the most attractive fitness tracker, but it records training sessions and daily activities with aplomb.

Continuous and accurate heart rate monitoring. In-depth sleep analysis. Can create custom training programs. Waterproof. Competitively priced.

No onboard GPS. Clunky design. Grainy screen.

Bottom Line: The fairly priced Polar A370 isn't the most attractive fitness tracker, but it records training sessions and daily activities with aplomb.

Polar A370 Review: This Fitness Tracker Has Heart


The A370 is a vast improvement over the A360. It offers accurate, continuous heart-rate tracking; connected GPS; deeper sleep insights; and a better band clasp at a lower price than Polar's previous band.

Large, colorful display ; Accurate heart rate-tracking during outdoor workouts ; Useful sleep insights ; Waterproof

Connected GPS can be unreliable ; Battery life could be better ; Too expensive for what it offers

Polar's A370 fitness tracker gets a boost from continuous heart rate-monitoring, connected GPS and and a colorful display, but the GPS is wonky.

Polar A370 In-Depth Review


This is pretty much the last round of deals on sports tech devices, including solid offerings from GoPro, Garmin, Fitbit, Suunto, Velocomp, Tacx and more! Pretty much all those brands are offering deals on their latest devices. I've consolidated them...

Polar A370 review


Polar adds GPS features to its heart rate-tracking band

Phone notifications ; Can GPS track runs with the help of a phone ; All-day HR tracking

Only 2-day battery life with all features switched on ; Chunkier than the competition ; GPS not in-band

A smarter-than-average fitness tracker that can GPS track your runs and walks with the help of a phone. Battery life is relatively poor, though, and it’s bulkier than much of the competition.

Polar A370 review: Not worthy of your wrist


Uncomfortable, chunky and overpriced, the A370 is a rare misstep from Polar

The Polar Flow app is excellent ; Micro-USB charging

Overpriced, considering its features ; Questionable build quality ; Unattractive design ; No GPS

Even if the A370 retailed for £130, I’d still suggest getting the Fitbit Charge 2 or Alta HR instead. At £170, it just makes saying so a no-brainer.

Polar A370 review: Not fighting fit


Uncomfortable, chunky and pricy for its features, the Polar A370 is an easy pass

Ultimately, though, this counts for nought if the product isn’t that great and that’s sadly where I end up with the A370. It doesn’t look great, isn’t hugely comfortable or easy to use, relies heavily on your phone and is outdone by cheaper, better...

The Polar A370 activity tracker monitors your fitness, sleep and health, all while letting you know how popular you are (or aren't) by syncing to your mobile notifications. It has a decent-sized screen and continuous heart rate monitoring, but the real...
