Pester

Pester provides a minimal‑interface way to create, manage, and clear alarms and timers on macOS. Users can set a timer or alarm, then dismiss or snooze it using only keyboard commands if desired, making the workflow fast and unobtrusive. The application supports several alert methods, including audible sounds, spoken announcements, and desktop notifications, giving flexibility in how reminders are delivered.

The tool is aimed at macOS users who need quick, disposable timing without opening a separate app or navigating menus. Its design emphasizes simplicity and keyboard‑centric operation, which can be useful for developers, writers, or anyone who works primarily from the command line or prefers to stay focused on other tasks.

Pester is distributed as a compressed disk image for macOS 10.12 and later, with earlier builds available for older OS versions. The source code is hosted on GitHub, and the project is listed as stable, indicating it has reached a mature, production‑ready state.
