Expert's Review

"The Swiss army knife of calendar apps"

Reviewed by / Oct 28, 2014

In three words: perfect calendar app

aCalendar is everything I ever wanted in a calendar app. It's super simple, ultra customizable, eminently navigable, and practically perfect in every way.

If you've connected your device to your Google account, aCalendar will automatically import data from any calenders you've linked there. Swap between a month, week, and day view with swipes that just make sense, smoothly transitioning between each view. Events are grouped by color so you keep your various task lists organized, and you can add new events right within the app, even scheduling them to recur if you like. Birthdays are automatically imported from your contacts list. Widgets are gorgeous and available for all three views.

It's lightweight, doesn't drain your battery, totally free, and doesn't have a single ad. Can I get a round of applause, please?

If you upgrade to the premium version, you get even more views plus extra themes and business.oriented features like free/busy settings and sharing files. Also, proceeds go towards helping protect the endangered Mountain Tapir. Seriously, I want to give these guys a kiss.

I couldn't find a single thing not to love about aCalendar. Very, very highly recommended.

    Great app, especially when combined with the Smooth Calendar app, but I liked it better when the current day could be highlighted entirely in its box instead of just an outline around the the box. Return that feature and I'll give 5 stars again...

    I have used this app for several years and its amazing! I do have one question though. Since the update, the size of the calender gets very small for some reason. I have to resize it constantly. What am I doing wrong? Keep up the GREAT work!
