Business Calendar 2

“The professional and versatile app for reliable, complex calendar management. Highly customizable and in perfect sync with Google.” No doubt about it, Business Calendar 2 is a great app for Android that I would not want to be without. Which, for me at least, makes it even more disappointing that time zone management still does not meet my expectations. Will we ever see a reliable implementation of multi-time zone events?

Syncronisation of your calendar and contacts with services other than Google is easy using CalDAV-Sync and CardDAV-Sync, respectively.
