Fitbit has released a new update for its wearables OS, and adds some big new health and smart features to its line-up of devices.

Fitbit OS 5. 7 is the newest iteration to the fitness tech giant's software, providing some advanced features users may be curious about. There's also a new Google Assistant built-in, offering up something closer to a full-time personal assistant for your fitness.

In my Fitbit OR will let me order from the website of Anya's favorite Italian restaurant with a tap of my wrist.

For example, if I order a set of items, the "Sign Up" on the watch shows a notification that read I have enough credits to order. The order will be complete when I receive the order confirmation (eventually). For larger orders, Google Assistant will allow me to order more from the website using just a tap of my wrist.

Additionally, Fitbit says it will soon include Apple HealthKit support in its smartwatches.

The new features revealed today include Siri-like notification support, new app notifications, fitness tracking, intention notifications, and a more robust Fitbit Health app.

Continuing the same approach that was introduced last year, users will be able to browse through a merged user interface for fitness tracking and fitness related actions that are grouped as "progressments." Workouts, for instance are grouped under "training." Further, users can "tune" these types of workout progress and receive personalized results.

If I wanted to unlock my smartwatch and check the time, for example, I could access a fairly long list of recently completed fitness activities. A recently forgotten fitness activity could be found in a set of links that will open a new video on my phone or watch.

Apple added support for inter-connected fitness bands (which notably contains a Fitbit Flex) in watchOS 3 earlier this month. Fitbit's set of consumer wearables introduced a Dash button gesture in Marshmallow, allowing users to quickly and easily interact with more features on a smart device.

Fitbit OS 5.7 will be available to new owners of the Fitbit Blaze 10.2 Series 2, Fitbit Council, Fitbit Charge 2, Fitbit Charge HR, Fitbit Surge, Fitbit Alta HR, Fitbit Ella, Fitbit On Run, and Fitbit Charge 2. Regularly $199, Fitbit's products will also launch with a new feature, called "Automatic Latitude Detection," which determines the wearer's specific fitness tracks to help app developers write more accurate fitness marketing experiences.
