When you're thinking about scheduling and roadmapping your day, Friday is the planner to help you be the most productive.

"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
