Fitbit Studio was a web-based tool that allowed developers to create apps and clock faces for Fitbit OS smartwatches. However, Fitbit has shut down Fitbit Studio as of April 20, 2023, as part of its efforts to streamline development tools[1]. The company now recommends using the command-line SDK for development, which supports building and installing projects using preferred code editors and version control systems[1].
Regarding the Fitbit Versa 4, it does not support third-party apps, and Fitbit has no plans to offer such support for this device[1]. While developers can create clock faces for the Versa 4, the process is limited compared to previous models. The Versa 4 lacks Wi-Fi connectivity, which further complicates app installation and development[1].
To develop clock faces or attempt to install custom content on the Versa 4, you would typically need to use the command-line interface (CLI) tools provided by Fitbit. However, as of now, there is no official SDK support for the Versa 4, and any development efforts would require unofficial methods or workarounds[4][9].
Steps to Develop Clock Faces for Fitbit Devices (General Process)
1. Create a Fitbit Developer Account: Start by signing up for a Fitbit developer account if you haven't already. This will give you access to the necessary tools and resources[2].
2. Use the Command-Line Interface (CLI): Since Fitbit Studio is no longer available, you would use the CLI tools to develop and install projects. This involves installing Node.js and using commands like `npx create-fitbit-app` to scaffold a new project[2].
3. Build and Install Projects: Use commands like `npx fitbit-build` and `npx fitbit` to build and install your projects. You will need to authenticate through the Fitbit shell to install apps or clock faces on your device[2].
4. Develop Clock Faces: While you cannot develop full apps for the Versa 4, you can create clock faces using the CLI tools. This involves designing and coding the face using JavaScript and SVG files[5].
Challenges with Versa 4
- No Official SDK Support: The Versa 4 does not have official SDK support for app development, limiting what developers can create for the device[4].
- No Third-Party Apps: Fitbit does not plan to allow third-party apps on the Versa 4, focusing instead on health and wellness features[1].
- No Wi-Fi Connectivity: The lack of Wi-Fi on the Versa 4 complicates the installation and management of custom content[1].
In summary, while you cannot use Fitbit Studio to develop apps for the Versa 4 due to its shutdown and the device's limitations, you can explore creating clock faces using the CLI tools. However, this process is not officially supported for the Versa 4, and any development would require unofficial workarounds.
