Calynda is a free calendar app that you can use to organise your life.
For years, I searched for a decent online calendar. I tried both Google Calendar and iCal at various times but found both to be lacking a lot of features I wanted in a calendar. So I set out to create one myself.
Calynda is designed to keep life organised while keeping the interface light and intuitive. I also wanted to make it better suited to use cases that neither iCal nor Google Calendar lend themselves easily to.
Calynda is still a work in progress, and I expect that to be the case for many years to come.
