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.
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.



  • Thanks for sharing that – I had heard about event calendars working their way into places pages, but hadn’t quite seen one in the flesh yet.

  • Hi. I just downloaded your app and so far I like it. I’d like to know how to change to colour of different things like anniverarys vs birthdays. Right now they are the same colour. I have the free version. Thanks.
