Odacla

Free, open-source, fully offline automatic time tracker for desktop

About Odacla

Odacla is an offline desktop time tracker that automatically records which applications you use and sorts them into categories such as coding, study, or entertainment with a rule engine. It offers daily goals with progress rings, a lane-style timeline of the day, manual entries and a menu-bar timer, and CSV or JSON export. All data stays in a single local SQLite file — no account, no cloud, and no telemetry.
