"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.

Developer's original description available here
9/10 "an almost perfect calendar" - Softonic, September 2013

FEATURES
● intuitive navigation with smooth transitions between day, week and month view
● 48 colors per calendar, 12 per-event colors if supported by the calendar (Android 4.1+ with Google calendars only)
● flexible recurrences (e.g., every 2 weeks or every 3rd day - first select weekly or daily, then set the interval)
● birthdays with photos from your addressbook and editing
● Fullscreen widgets for all 3 views plus floating 7 days
● uses Android's native calendar backend and synchronization
● no battery drain (aCalendar gets push updated from the system instead of using frequent polling)
● moon phases and zodiac signs for birthdays
● QR and NFC barcode sharing of events
free
● no ads

EXTRA FEATURES only in aCalendar+
With aCalendar+ you get a dozen of extra features including more views, advanced settings, Tasks, more color themes and public holidays.
Also you'll find business-oriented features like invitations, free/busy settings and sharing as text or file.
Finally your purchase helps protect the habitat of the endangered Mountain Tapir.

USAGE
● move forward and backward by swiping vertically or volume rocker
● switch between calendar views with a horizontal swipe (opens the day or week you start the swipe gesture on) or double-tap for day view
● tap to open event
● long-press to add new event
● long-press on mini-month to go to today or jump to date
● tap on photo to open quick contact menu
● 3-finger-tap to go to today

TRANSLATIONS
native language support for around 30 languages. Those are mostly user-contirbuted, please contact me if there is a bad translation or you'd like your language added!

PERMISSIONS
aCalendar only asks for mandatory permissions for its functionality: Read and write contact data for birthdays as well as read and write calendar data for events. 'Send Email to guests' is bound to 'write calendar data' by Google. NFC is for sharing events by touching another NFC-enabled phone, and requires manual confirmation.

APP2SD
Unfortunately app2SD cannot be supported, because homescreen widgets do not work from SD. This is an Android limitation. But aCalendar is optimized not only for speed but also for size.

LOVE
♥ aCalendar is made with love, sweat and tears in the heart of Munich. If you like aCalendar, please rate or comment and recommend it to your friends. Also now available is aCalendar+ for some extra features ♥

FREE
aCalendar is free and will stay free and ad-free. No features will be taken away, but some advanced calendar features might only come to aCalendar+.

    Far the best of about five Calendars I tested, nearly perfect.
    A nice additional feature could be a fast switch form monthly to weekly to dayly view.

    Google's latest update has sadly ruined the best part for me, the ability to view the whole month with specific events shown. Very good app
