When someone says Fitbit, you almost instantly know that they are talking about some type of wearable device. The Fitbit Alta HR is the lifestyle brand’s latest addition to its fitness tracking stable, marking it as the world’s slimmest device which feature heart rate sensors to the bracelet-like activity tracker.

The Fitbit Alta HR offers advanced health metrics to non-fitness types, and is designed for those looking to achieve more modest health goals. As well as 24/7 heart rate monitoring, the Alta HR heralds big improvements in sleep tracking, which will also roll-out to existing Fitbit products.

The Alta HR manages to pack in its PurePulse optical heart rate sensor in a band that’s the same thickness as the first Alta and 25% slimmer than the company’s existing Charge 2. It’s impressively small and light, and there’s virtually no visual difference from its immensely successful Alta fitness tracker.

Things get a lot more detailed on the Alta HR, with the sleep graph now showing metrics for awake, REM, light sleep and deep sleep cycle. The Alta HR uses heart rate variability to determine your sleep stages, which makes it even more curious that the breathing hasn’t made it to this predominantly wellness-focussed device.

Encouragingly, actionable insights are now baked into the app to help users get better sleep. These include analysis of individual’s sleep information, correlations and patterns between exercise and sleep, bed time reminders on the Alta HR itself, and the ability to create a sleep schedule.

Like its predecessor, the device is still predominantly a female targeted fitness tracker, although there are gun-metal and leather versions that don’t look out of place on male users.

The standard Fitbit Alta HR retails for RM730 while a special edition that include colour-coded body retails for RM820. Available in a host of coloured bands to suit all tastes, allowing users to stay true to their personal style. Head over to Lazada or any selected retailer near you to purchase the device.
