There's little denying that the Fitbit Alta HR is a reiterative product. It looks very similar to the regular Alta and a bit like a smaller Charge 2, but it sits somewhere between the two in terms of features. When it was announced last month, Fitbit called it the slimmest fitness tracker with continuous heart rate monitoring, a distinction that had to be made to justify the same $150 price as the Charge 2 while packing fewer options on paper.

I came to the Alta HR a bit skeptic. The Charge 2 was by far the most convincing Fitbit I'd ever used and even one of the best all-around activity trackers on the market.
