ROCCAT Swarm is a free Android app developed by ROCCAT GmbH that serves as the perfect companion for your ROCCAT hardware. It comes with a host of convenient features that transform your smartphone into a powerful tool, enabling you to get the most out of your device.

The app's main features include showing your active driver profile, turning auto-profile switching on or off, setting a profile as your default desktop profile, switching between different illumination effects, adjusting illumination effect speed, brightness, and turning illumination on or off. Other features include showing APM (actions per minute), mistakes per hit (backspace presses), and hardware monitoring statistics of your host PC. Moreover, you can start programs and games directly from the app.

However, it's important to note that the ROCCAT Swarm app is not a standalone piece of software. You need to download the corresponding ROCCAT Swarm PC host software from the developer's website in order to use the app. The app is only compatible with Windows 7, 8, and 10.
