It covers almost everything you'd want to know about your phone's hardware and software.

• Widgets and Shortcuts: The app allows you to add widgets or create shortcuts for specific information directly on your home screen, giving you quick access to the data you need without launching the app. This adds convenience and saves time, especially for frequently monitored stats like CPU or RAM usage.
