"I love how Google Calendar automatically uploads everything to the cloud. I also love how it suggests locations based on the address one types in (of course it doesn't do this for private addresses, but it is still a handy feature.) It will set reminders by month, day, hour, or minute, and it also asks if one wants to set up recurring appointments for a number of weeks, a number of days, or annually (handy for Birthday reminders.) The app will also convert between time zones across the world—another useful feature." — G2Crowd
