Fitbit OS Simulator

Fitbit OS Simulator is a tool provided by Fitbit that allows developers to build, test, and preview applications and clock faces for Fitbit OS , the operating system used by Fitbit smartwatches. The simulator runs on Windows and macOS, and provides a virtual environment that emulates the features and functionality of a real Fitbit device. This allows developers to test their code without the need for a physical device, and to preview their work on a virtual watch face or app screen.
