BreakTimer

BreakTimer is a free, open-source desktop application designed to encourage regular breaks during computer use. It helps users manage prolonged screen time and reduce habits associated with eye strain and repetitive strain injuries. The software provides configurable reminders at intervals selected by the user. Breaks can appear as simple desktop notifications or fullscreen windows that interrupt ongoing work. Users can customize break duration, frequency, and the messages displayed during rest periods. It supports scheduled working hours to prevent reminders outside designated times. An idle detection feature can automatically restart the break countdown when the computer has not been used. Available for Windows, macOS, and Linux, BreakTimer offers a flexible approach to managing computer work and rest schedules.
