When life gets busy, it can be difficult to stay on top of everything. Between getting the kids to school, making sure you're on time for that lunch meeting, and remembering to call your Grandmother on her birthday, it can be easy to let things slip through the cracks. That's probably why so many people have moved away from paper planners, and instead prefer to use an app on their phone to keep track of their schedules.

So, with tons of options and ways to customize how you keep track of your life, we want to know which calendar app is your favorite. There are dozens of calendar apps on the Google Play Store but we've narrowed the list down to some of the best calendar apps available. This week we've throwing six suggestions out there: "aCalendar," "Google Calendar," "Cal," "Jorte," "Today Calendar," and "DigiCal." Use something else? Pick that option, and be sure to let us know what you do use.

Is using a calendar app second nature to you, or do you still prefer a paper planner? Was your favorite calendar app not on our list? Be sure to let us know about it in the comments!
