Fitness device maker Fitbit has announced the new SDK 5.0 OS for Fitbit Sense and Fitbit Versa 3. Fitbit OS 5.0 is claimed to be the company’s largest and most impactful smartwatch update since the launch of Fitbit Ionic in 2017.
Fitbit OS 5.0 comes with a new design language and an updated UI toolkit for app developers As per the website description, “This update includes support for both new devices, the new user interface elements, and a new extension to the Document API that allows developers to easily implement multi-screen applications that support the new navigation model with swipe-back gesture.”
Fitbit OS 5.0 comes with Raiju, a new system font. All elements—buttons, backgrounds, icons, colors, and tiles—have received significant visual improvements, claims Fitbit.
The company says that it has adjusted base text size, button size, and tap targets to increase user accessibility. These changes have been made to make the device easier to use during activities such as running.
As per the webpage description, “With the new user interface in Fitbit OS 5.0 navigation in an app is achieved by stacking views. Each new view should slide into view from right to left when it’s loaded, then slide out of view from left to right when it’s unloaded. The animation for loading a view is controlled by adding <animate> tags to your view, but the unloading animation is handled automatically by the system.
In order to achieve this new user interaction in your application, we’ve introduced some enhancements to the Document API, and the swipe right gesture which can be used for the swipe-back event.”
