The tool is intended for anyone who needs to verify the speed and reliability of their network, such as home users, office workers, or IT personnel troubleshooting connectivity issues. Its design follows a straightforward workflow: launch the application, run a test, and view the reported figures without additional configuration or external services. The software is marked as stable, indicating that it has reached a mature state suitable for regular use on supported macOS systems.
