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!

great colour

A370 was replacement for A360, which was lost whilst canyoning. V similar to previous model, a few extra features, most obvious being strap - simpler & looks stronger, hopefully!

Heads up – April 8th, 2019! The Fitbit Alta HR (the one with the optical HR sensor) is currently $40 off – down to $89 (or Amazon here )! This is the best price we've ever seen for this unit, and the lowest price we've ever seen for a HR enabled mainstream activity tracker.

Polar's new A370 premium fitness tracker has some small but important feature upgrades over the A360: It adds 24/7 continuous wrist-based heart-rate tracking and the company's Polar Sleep Plus analytics.

Adding continuous tracking heart-rate monitoring to its list of features, the A370 is a modest upgrade over the earlier A360.
