The Silicon Labs Thunderboard app is the perfect companion for developers working with the Thunderboard kits. These kits are EFR32-based development and prototyping platforms specifically designed for IoT applications. With the Thunderboard app, users can connect to the pre-programmed firmware in the Thunderboard kits and access a range of features and demos.

The app offers three different demos that make use of the on-board sensors. The motion demo provides a 3D render of the physical board, allowing users to visualize and track its movements. The environment demo displays the values from all the on-board sensors, providing valuable information for monitoring and analysis. Lastly, the I/O demo enables users to control the LEDs on the Thunderboard and receive button state indications.
