Koncentro is a free, open-source productivity application that combines Pomodoro timers, task management, and website blocking. It helps users organize their work into focused sessions and reduce online distractions. The software supports timeboxing, allowing users to allocate a fixed duration to individual tasks. Its website blocker can restrict distracting websites through customizable blocklists or allowlists. Users can create separate workspaces with independent task lists, timer settings, and blocking rules. The application features a modern interface inspired by Microsoft's Fluent Design, including Mica effects on Windows 11. Built with Python and PySide6, Koncentro is available for Windows, macOS, and Linux without requiring Electron.
