Pester

Pester is designed to let you set, dismiss or snooze an alarm or timer as quickly and painlessly as possible, entirely from the keyboard if you wish. Alert options include sounds, speech, Growl and OS X notifications. Use Pester to remind you to catch the bus or attend an upcoming meeting.

Note: This version requires OS X 10.9 or later running on a 64-bit Intel processor; 1.1b19 is the last version of Pester to support OS X 10.7 and 10.8 on 32-bit Intel.

• 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 10.9-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.
