Windows Meeting Timer using C#, WPF and custom analogue clock control. Designed for use in Kingdom Halls where the meeting format is predefined, but has a "manual" and "file-based" mode that can be used to configure the timers as required (and so can be used in other settings too).
If you just want to install the application, please download the OnlyTSetup.exe file.
See the wiki for basic instructions.
