System activity monitor for Mac and iPhone
The monitoring app you all deserve!
Usage offers extensive customization: users can select individual monitoring components for the menu bar, choose graph colors and types, set refresh rates, and configure the app's behavior. Beautiful widgets provide instant insights, and the interface matches Apple's design language.
Usage is designed as a privacy-first, lightweight app that never tracks or shares device activity data. It stores all monitoring data locally and syncs only via iCloud, making it suitable for users concerned about data privacy. The app is optimized to be CPU-friendly and does not drain battery.
Usage syncs monitoring data via iCloud across all Apple devices, allowing users to view system activity on any device. This is particularly useful for developers and power users who work across multiple Apple platforms and need consistent performance insights.
Usage Pro unlocks processor temperature, fan monitoring, graphics card usage, and detailed process tracking. The optional Helper app (notarized by Apple) bypasses Mac App Store sandboxing to fetch additional system sensors, providing deeper diagnostics than the free tier.
Usage provides a lightweight, customizable menu bar widget with 40+ configurable components that display system metrics at a glance. Users can select exactly which stats to show (CPU, RAM, disk, network, battery, temperature, fans) and choose graph type and refresh rate, keeping the desktop clean while maintaining instant visibility.
