Ketchup is a native Pomodoro timer designed for KDE. It implements the familiar productivity technique of alternating periods of concentrated work with regular breaks, while keeping the interface and configuration intentionally straightforward.
The application is aimed at people who want a small dedicated timer rather than a broader project-management or task-tracking system. Focus and break durations are configurable, so users are not restricted to the traditional Pomodoro timings. Ketchup can also move directly to the next period after an alarm is dismissed, reducing the need to keep returning to the application between sessions.
This is free and open source software.
Key Features
- Pomodoro-style work and break cycle.
- Set the duration of focus periods.
- Configure the length of break periods independently.
- Select a custom ringtone for timer alarms.
- Automatically advance to the next period after dismissing an alarm.
- Native application designed to integrate with KDE.
- Graphical timer display showing the current work or rest period.
- Simple workflow intended to avoid distracting configuration while working.
- Suitable for users who prefer flexible session lengths rather than fixed Pomodoro defaults.
