Patina records foreground app usage as local, quiet, and trustworthy personal desktop time records.

• Records foreground apps automatically, without manually starting or stopping timers.
• Handles idle, lock, sleep, and abnormal-exit boundaries to keep records more trustworthy.
• Keeps data local by default, with no account, cloud sync, or server dependency.
• Lets you manage app names, categories, colors, stats exclusions, and window title capture.
• Provides lightweight local tools such as reminders, timers, and Pomodoro.
• Keeps the interface restrained, clear, and low-interruption for long-term daily use.

Prebuilt versions are published on GitHub Releases:

• Download latest

Open the release page, download the Windows installer, and run it. Patina currently targets Windows 10/11 desktop use.

The optional Patina Web Sync browser extension is published separately and is used to identify webpage titles in browsers.

• Automatically records the current foreground app and turns activity into time records.
• Detects idle, lock, and sleep states to reduce invalid time in statistics.
• Handles record boundaries after long-away periods and abnormal exits, reducing accidentally merged time.
• Reduces missed effective activity in low-interaction scenarios such as videos, meetings, courses, and livestreams.

• Review effective activity, app rankings, and category distribution in today's overview.
• Use the timeline to review activity by date and inspect app switches and window title details.
• Understand long-term time distribution through trends, heatmaps, and app curves.

• Rename apps and adjust categories, colors, and statistics rules.
• Exclude apps you do not want in statistics, or disable window title capture for specific apps.
• Export local backups, restore backups, and clean up historical records.

• Create one-off reminders and app usage limit reminders.
• Use stopwatch, countdown, and Pomodoro for active focus tasks.
• Tool state stays local and does not replace automatic tracking records.

Time tracking has long-term value only when the records are trustworthy. Patina focuses on these boundaries:

• Foreground app recognition: records the window and app that are actually in the foreground, reducing temporary-window and system noise.
• Idle handling: idle time does not continue counting as effective activity.
• State boundaries: handles record boundaries after lock, sleep, resume, long-away periods, and abnormal exits.
• Effective-duration stats: rankings, distributions, and totals use effective activity time, not just open spans.
• Title capture control: window title capture can be disabled per app to reduce unnecessary sensitive information retention.
• Local data control: core data stays local, and backups, restores, and history cleanup are initiated by the user.

Patina currently focuses on personal local time records:

• Windows 10/11 desktop use
• Personal local data storage and control
• Automatic tracking, review, classification, and backup or restore
• Lightweight local tools

It is not currently aimed at team collaboration, account systems, cloud sync, multi-platform sync, or heavy AI insights.

• Rust
• Node.js 18+
