A photo of Google Calendar, one of the best calendar apps for Android.
Calendars are useful tools. Even paper ones are great for remembering dates, taking out the trash, and keeping track of family birthdays. Some of the first mobile apps were datebooks and calendars. They’re useful to this day for exactly the same things as their antiquated paper ancestors. Surprisingly, the technology behind calendars has changed very little over the years. Most calendar apps are still just massive datebooks with customization features. Still, there are plenty of great ones out there. Here are the best calendar apps to keep you organized!

Other apps with included calendars

Price: Free / Varies
DOWNLOAD ON GOOGLE PLAY
Calendar apps are great. However, some people just need a basic solution. Sometimes, other apps include a calendar as part of their functionality. Those calendars aren't as powerful, but they get the job done for basic stuff. Some email apps like Newton or Outlook have calendars. Widget packs like Beautiful Widgets and HD Widgets have calendar widgets as well. Even some to-do list apps like TickTick have calendars built-in. Even Facebook has a built-in calendar There are far too many list here. We recommend looking around for apps that cover multiple bases. That's a good start for basic calendar usage.

Of course, the stock calendar apps on most phones do a good job for the basic needs. They can do recurring tasks (usually), remind you of upcoming holidays, and create appointments and events. They don't have the extra features like the above calendar apps, but some people just don't always need them. Plus, most of them integrate with Google and Facebook Calendar at the very least. They're also free and pre-installed. These apps are generally free, already on your device, and do the basics. It might be worth it if you just don't want to use Gmail for whatever reason.
