We have just made Plancake Open Source, released under the AGPL license.
Plancake is a free personal organizer you can use to manage all your events, activities, projects and make plans.
Plancake also integrates with Google Calendar seamlessly.
There is an API and an Android application, too.
We would like some developers to join the project and help us make Plancake the best tool to organize your private and professional life.
This is the link to the hosted application:
By the way, do you know any place where I can submit this application? I have already done so at Symphonians.
Thanks for reading,
