WHAT YOU CAN DO
Explore the key features.
Timeline & work blocks
View the day's activity on a colored timeline and group nearby sessions into work blocks. See recorded time, leading categories and window-switch counts.
App, site & period statistics
Explore category, app, domain, hourly and weekday usage with donut and bar charts. Select dates or ranges and drill into details.
Custom classification
Classify activity into 11 categories including coding, documentation, research and entertainment. Add or edit app/site rules and search or filter recent activity.
Projects & reports
Review VSCode workspace and Jira/Confluence project time. Export ranges to HTML, Markdown or CSV, and weekly reports with previous-week comparisons to Markdown or HTML.
Stored on your PC
Keep records in local SQLite without transmitting them. Keystrokes, screenshots, credentials and full URLs are not stored; window titles are masked.
IN YOUR EVERYDAY LIFE

Choose dates or periods to inspect hourly and weekday statistics. Use the patterns as a reference when planning your next week.
Keep a weekly reflection note
Save weekly reports with changes from the previous week as Markdown or HTML, and keep them alongside your own reflections.

THINGS TO KNOW
Before you start.
The database is stored at %LOCALAPPDATA%\FlowLens\flowlens.db, with automatic cleanup after 90 days. App names, masked titles, domains, times, categories and minimal project identifiers are recorded.
Domain extraction supports Chromium browsers such as Chrome and Edge. Firefox may provide app-only records depending on the environment.
Closing the dashboard leaves tray tracking active. Use Exit in the tray menu to stop the application.
