What is a .FBA file?
An .FBA file is a special type of file used for apps that work on Fitbit devices, like the smartwatches and fitness trackers many people wear to track their steps, heart rate, and more. These files are created by people who make apps using tools provided by Fitbit, such as Fitbit Studio, which is a web-based tool, or the Fitbit Command-line Interface, which is more advanced and used through coding commands.
Inside an .FBA file, there's everything the app needs to work. This includes the app's source code, which is like the recipe for how the app functions; the manifest, which tells the Fitbit device what the app is and what permissions it needs; and assets, which are things like images or sounds the app uses. All of these components are packed together into a single file that's compressed, similar to how a zip file works, to make it easier to handle and distribute.
When a developer is done creating their app, they upload the .FBA file to the Fitbit App Gallery. This is a place where anyone with a Fitbit device can go to find new apps to add to their device, expanding what their Fitbit can do beyond its basic functions.
To open an .FBA file, you would typically use the Fitbit Command-line Interface if you're a developer looking to work on or inspect the app. This tool allows developers to interact with the app file in various ways, such as installing it onto a Fitbit device for testing. For those who are creating or editing the app, Fitbit Studio is another option. It's a more user-friendly, web-based environment where developers can write code, design the app's interface, and package everything into the .FBA file format.
For the average user, there's no need to open an .FBA file directly, as the installation of apps from the Fitbit App Gallery is handled through the Fitbit mobile app or website, making it easy to find and install new apps onto their Fitbit device without worrying about file types or coding.
