UsageOS review
A private, open-source Mac tracker for reviewing activity without cloud storage.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
UsageOS is a free, open-source desktop time tracker for people who want a private view of how they spend time on a Mac. It records active applications and window titles, with an option to read the current browser tab address, then organizes activity into categories such as work, browsing, messaging, and entertainment. Data stays on the device in a local SQLite database, with no cloud account or telemetry, making the product a fit for individual users who prioritize local control over shared administration.
Pricing is straightforward: the Free plan includes on-device time tracking, open-source availability, and a macOS desktop application. The published product details also support usage reports, including daily recaps, weekly views, timelines, activity by category, and project-based views. CSV export provides a practical path for taking usage data into another workflow, while automatic history deletion after 30, 90, or 365 days gives users control over retention. Exclusions for apps and sites, along with private-title hiding, add further control over what is recorded or displayed.
UsageOS stands out through the depth of its local activity record and review tools rather than through intervention. User-defined rules can group apps, sites, and window-title words, which suits people who want tailored reports across work and personal activity. Its focus is measurement: people looking for app blocking, scheduled limits, or focus sessions should choose a different type of screen-time product. UsageOS is the better choice for Mac users who want free, private, customizable tracking and are comfortable reviewing patterns instead of enforcing limits.
