BusyMac has been living up to its name while working on BusyCal 3, a major update to the company’s full-featured alternative to Apple’s Calendar app. BusyCal 3 features a modern look, smooth navigation via trackpad swipes, the inclusion of travel time in event alerts, timed to-dos that appear inline with calendar events, and an improved Info panel. A quick 3.0.1 update addressed a few crashes and other bugs. Joining the Mac version of BusyCal is the $4.99 BusyCal for iOS, which offers the same calendaring features in a version optimized for the iPhone and iPad. ($49.99 new, $29.99 upgrade, 10.7 MB, release notes, 10.11+)
I very much dislike the much lower contrast between calendar items, especially in the iOS version. An extra problem there is the inability to have the week always start at one day like Monday or Sunday; it starts at Today, which can't be altered.
On iOS I'm sticking with WeekCal.
