Stats is a macOS system monitor that displays real-time information in your menu bar.
The tool addresses the need to keep system metrics visible without opening separate applications or windows. It works by running as a menu bar application that continuously monitors various hardware and software metrics, displaying them as compact icons and widgets that you can glance at without interrupting your workflow. The application uses an SMC helper for privileged access to sensor data and system information that would otherwise be unavailable to standard applications.
Stats suits developers and power users who want persistent visibility into system performance without dedicated monitoring windows. It works well for anyone running macOS 12 or newer who needs to track CPU, GPU, memory, disk, network, battery, temperature, and sensor data simultaneously. The tool offers modular monitoring, so you can enable only the metrics you care about, which helps reduce energy impact. The most resource-intensive modules are Sensors and Bluetooth; disabling these can reduce CPU usage and power consumption by up to 50% in some cases. The application provides both menu bar icons and desktop widgets, though widget communication is disabled by default due to system process limitations and must be explicitly enabled in settings.
Development activity shows consistent maintenance with attention to macOS compatibility and system integration details. The project maintains a legacy version for older systems and actively addresses macOS-specific issues such as menu bar privacy controls introduced in recent releases. The maintainer provides clear documentation of known limitations, such as the inability to control menu bar icon ordering and the communication overhead between the app and system widgets. The codebase is written in Swift and distributed through both direct download and Homebrew, with an uninstall script that thoroughly removes all application components including privileged helper tools.
