Polar A370

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.

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.

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.

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...

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.
