Everything you expect from a calendar, and nothing more.
Never miss an important appointment
Example: remember that chat you scheduled with Barack? Don’t be late!
Remember the most important calls
Example: Call your Grandma and ask her out for dinner.
Emails are part of our life, schedule them.
Example: The Dude keeps asking some news about your bowling tournament. Keep him updated!
Syncing with iCal
Example: Import your future events and start using the First Calendar immediately.
