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.

    Just changed from iphone. This app is missing some features like huge list of emoji icons to put in your appointment (helps in month view to identify what it is) and also basic feature of making all appointment have a bar display rather than just text as

    Just transferred this to my new S3 only to find a heap of appointments missing and some moved to a different day. The print is so faint I can't read it even magnified. Considering uninstalling.

    I wish there was the option to load holidays onto the calendar since that can be a big deal for scheduling ahead.

    This would be a decent app if the month view widget actually stayed in place. It disappears from the home screen every time.
