Polar's new A370 fitness-tracking wristband is a course correction from its predecessor, the A360 , which was lacking in a few key areas. The A370 improves upon the last-gen model, with continuous heart-rate monitoring, GPS (sort of), an easier-to-fasten band clasp and a new sleep-tracking tool...

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

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'm a recent Polar convert. Ever since reviewing the M430 in October 2017 it has been a faithful companion on one wrist on race day. Aside from being a generally brilliant running companion, it also does a great job of highlighting when other wearables I'm reviewing aren't pulling their weight.

Polar is a company known, historically, for making heart rate sensors and hardcore GPS tracking watches - but its new fitness tracker, the Polar A370, is far more mainstream.

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

heart rate not accurate all the time and battery life is very short... not sure why?

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.

Très facile à ma?triser; informations qui semblent réalistes. Bon achat!

Arrived with no clasp to buckle the strap, and the box was dirty and damaged. It looked like a display model. Resulted in purchasing a 3rd party strap from another company to replace the damaged one due to the Process of refunding and exchanging being such an inconvenience.

I had high hopes for the Polar A370. The Polar M430 is one of the best things I've ever put on my wrist . True, that's not an enormous list, but I have reviewed a lot of wearables, and the Polar M430 has passed the test of time.

The Polar Flow app is excellent; Micro-USB charging

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

great colour
