GMinder is an open source Windows System Tray app that pops up to remind you about Google Calendar events.
GMinder’s original page, which contains some documentation about it, is http://reflectivecode.com/gminder/. After a few years, Greg stopped working on it and passed it over to Mike who maintained it at https://code.google.com/p/gminder/. However, in November of 2014 Google deprecated the Google Calendar API v2 which GMinder was using.
I’ve updated GMinder to support the new APIs and fixed a few issues while I was at it.
GMinder requires .NET 4.0.3 or higher to work.
