Editors' Review

Pester is a freeware alarm clock utility that provides a simple way to set timed reminders, along with a few cool extras.

Of course, you can use iCal and other scheduling software to alert you to upcoming events, but sometimes these apps are overkill--like, for example, when you're just putting something in the oven, or you're trying to remember to catch a bus. Pester occupies a middle ground between iCal and more bare-bones timers (such as egg-timer widgets), letting you quickly set an event, name it, choose a countdown or a specific time for the alert, and then (if you want) pick from a variety of alert options, including displaying a message, playing a sound (a standard alert, or even opening an MP3 or image file), speaking the name of your event aloud, and bouncing the Dock icon. Pester lets you set multiple alerts (unfortunately, there's no way to edit them), and you can snooze alarms with a variety of options. One of Pester's coolest features is the ability to create a hot key that lets you set alarms from any application.

Pester is officially beta software, and the interface isn't exactly pretty, but if you're looking for a simple, reliable timer with some flexible extras, Pester is a great, no-cost choice.

Full Specifications

What's new in version 1.1b23
  • Pester is now a 64-bit application.
  • Use AVFoundation, Apple's modern framework for video, rather than "classic" QuickTime. Note that this removes support for image/PDF display and playback of some movie formats; please let me know if (and why) you rely on any of these. Because of a limitation of AVFoundation, audio from movie playback will be sent to the system sound output device, rather than the alert device selected in Preferences.
  • Fix multiple issues related to tracking and validating recent media.
  • Fix an issue introduced in 1.1b20 in which movie alerts would play their audio only, not their video.
  • Fix an issue in which the All Alarms window could be invisible if alert restoration failed.
  • Fix multiple issues with setting and re-setting the Pester system-wide keyboard equivalent.
  • Pester no longer bounces its Dock icon when it is frontmost even if you have requested it to do so, since there is no supported way to do so in a 64-bit application.
  • Support natural-language date and time entry on macOS Sierra (10.12), by linking to Perl 5.16 on OS X 10.9รข??macOS 10.12.
  • Update to the current version of Sparkle.
  • Code cleanups and modernization without (intended) changes in functionality; remove some code which was never used.
