Synchd Up has the similar app available for all platforms and a plugin for chrome and Mozilla will be soon available.

Synchd Up is an interactive calendar application that will be synched with various other calendars to give the users a seamless platform for all scheduling and calendar activities. The high point of the application is that it will extract date from any website, so that users can directly create an event from the plugin and those events are synchd between mobile apps and plugin.

It also keeps track of the tasks that has been marked as done by user.
