Time tracking for billable work that should not need timers.
Lumen is automatic time-tracking software for freelancers, studios, agencies, and small teams that bill by the hour. The desktop app captures work as it happens, syncs a clean timeline across devices, and turns that record into reports that are ready for client review.
Why Lumen exists
Manual timers create incomplete records because they rely on perfect habits. People forget to start them, forget to stop them, and spend more time reconstructing the week than reviewing the work itself.
Lumen takes a different approach. The desktop app keeps the source timeline locally first, then syncs the parts needed for cross-device history and workspace reporting. Rules handle the repetitive classification work so reports become a review step, not a reconstruction step.
Team features are designed around trust: workspace owners get client and category totals, while personal app and window details stay visible only to the person who produced them. That keeps billing accurate without turning time tracking into surveillance.
Lumen today is a desktop app for macOS, Windows, and Linux paired with a web dashboard. The app does the watching; the dashboard does the explaining. Timelines, rules, clients, categories, and reports live there, and a workspace gathers a whole team's hours onto one invoice. It is built by a small team that bills by the hour too, which is why the product obsesses over the moment an invoice needs defending.
Product principles
Automatic by default
A tracker that depends on memory eventually becomes a chore. Lumen records the active app, window, and site while you work so the record starts complete.
Private by design
Raw activity belongs to the person who produced it. Workspace reporting is built around aggregate hours, clients, categories, and totals.
Built for billing
The product does not stop at a personal timeline. Rules, workspaces, client rates, and CSV exports turn tracked hours into invoice-ready records.
