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.

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.

  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 is a marked improvement on last year's tracker. The shift to more day-to-day wellness with the 24x7 HR will appeal to many, as will the sleep monitoring. The optical HR sensor is better, but still not perfect, but connected GPS definitely makes this more appealing as a fitness device.

  24/7 tracking, Added sleep smarts, Connected GPS

  Iffy Bluetooth connectivity, HR accuracy still slips, Chunky (but not all that funky)

At first glance, one might think that the A370 is just a modest update, potentially uncompetitive. But in reality it’s actually more than might meet the eye. By adding in the 24×7 HR tracking, the HR rebroadcasting, and connected GPS functionality, they both catch-up to competitors, but actually...

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

Polar A370: 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

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.

  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

Researched this a lot before purchasing, since there are several similar options out there. Very happy with this choice, synchronizes flawlessly once set up (you MUST follow the provided instructions to the letter).I like Polar software for monitoring activity on mobile app and on the cloud.

It is an awesome watch, easy to use. If used frequently you will have to charge it every 3 days approximately (with notification on), if not battery will last for about 4-5 days. Beautiful and conformable, definitely will recommend it.

It's a great fitness tracker, works on almost every kind of training. The battery lasts up to 04 days and i'm using this for weight lifting.

Great product. My wife suggested this activity tracker as her trainer recommended it to her. Said that it is more accurate than competitors. Only issue I had was The touchscreen was a bit slow on response time. Bluetooth connectivity to smartphone is simple and transfer to app is quick.

decent ..... not my favorite will be going back to my Tom Tom.... I really hate the fact that the screen goes black and I have to push the button to see my heart rate...so annoying!!

I love polar and I feel it's always been the most accurate device but now it has a slick look and tyhry added the sleep tracking. Love it so far!

Its sleep tracker isn't accurate at all; both the online app and phone app are not user-friendly; you can't see in-depth detail about what sleep it does track; if you need to edit your sleep record because the tracker didn't do it correctly, you can only change the slider by one hour; the battery...

Unfortunately it is constantly losing the GPS link to my iPhone. That makes it next to useless as a running watch. It also will not sync on occasion, last time it was out for three days before finally syncing up.

Lovely colour great for summer x

I hate that i had to set up my day and time throughthe computer, you just cant adjust it on the hand set like it should be
