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.

    Why have you changed the entry color to a low contrast blue from the earlier black with no option? Harder to see.

    I like this app. It helps me a lot. I dont have the pro version but the free one is good enough for me.

    The widget keeps updating and therefore momentarily blinks every few seconds a lot

    I want alerts. Sound, vibrate, pop ups. The only alert I get is from what came with the phone so while yours looks nice, what's the point of having it if don't alert
