Making an accurate wristband heart rate monitor, let alone one that’s also comfortable and stylish, is challenging. Fitbit’s latest attempt to strike that balance is the $150 Alta HR. A near mirror-image of the original Alta, the Alta HR is an updated model with slight design differences, improved sleep-tracking features, and a tiny optical heart-rate monitor inside of it.
The Alta HR is quite similar to Fitbit’s currently available Charge 2, but the Alta HR places more emphasis on the combination of a slim design and an accurate heart-rate monitor. Fitbit is banking on that combination encouraging users to wear a device all day and all night long. The Alta HR is proof that you can have a device that works as hard as you do without being ostentatious and without much sacrifice.
