Been using BusyCal 1.6 for a while now, and have recently been deciding whether to upgrade to the App Store version 2. BusyCal 1.6 has been great, offering a feature set that was sufficiently advanced above iCal to be worthwhile. However, the $50 price tag was too hard to swallow on it's own. As part of a bundle with Parallels for $50 total the price was right and it's been an exceptional value. I use the calendar for basic work/personal calendar functionality with Google Calendars. With the shift to the App Store, and the "introductory" $30 "upgrade fee" I've had to seriously re-examine whether version 2 of this software is actually worth the price. My conclusion? No. While pretty, it offers few useful features above Calendar.app in 10.8. My short list of advantages? The info pane shows the full location for meetings. Calendar.app cuts them off. Point to BusyCal. BusyCal has ToDo list functionality; Apple has moved the relatively worthless to-do list in iCal to Reminders and managed to make it even more worthless. 1/2 point to BusyCal, because it doesn't actually sync with reminders nor does it create a todo list that anything else can read. At least it's exportable. Calendar.app in 10.8 has excellent Google Calendar support (much better than iCal ever was), but not quite as good as BusyCal. Calendar.app has some issues keeping track of moved meetings where a restart of the app is required to re-sync. Point to BusyCal. BusyCal has status icons on meetings identifying meetings with attendees and recurring meetings. Calendar does not. Point to BusyCal. BusyCal has weather, and sunrise/sunset display. That's nice from a productivity standpoint. 1/2 point to BusyCal since I can live without this. BusyCal has an integrated info pane. Much nicer from a functionality standpoint. Point to BusyCal. If those features are good for you, and you do not currently own BusyCal, then $30 *might* be a good value. However, there is no real advantage I can see for BusyCal 2 over BusyCal 1.6 other than continued support and future bug fixes. BusyCal 2 drops features in favor of some improved eye-candy. All told, it's *maybe* worth $10 to upgrade from 1.6. $30? No way. $50? You're out of your mind. If there were a cheap upgrade path from 1.6 that reflects the actual improvement in the software I'd not give this a 2nd thought. As it stands, I'm simply looking for an alternative. Calendar.app is literally two small features away from replacing this product entirely. Asking me to re-purchase the app at an exorbitant price for what is essentially an AppStore-ified re-hash of what I already own (under the guise of "Mountain Lion support") is simply out of the question.

I really (!) couldn't work without BusyCal any more – since years. Together with BusyCal it's my killer combo in my daily work with the Mac and external teams.
Version 3.7.1

Have been using this for a very long time, and its incarnation before with Now Software. Users will have different preferences but for me this is solid and merges my Apple (personal) and Microsoft (work) calendars effectively. A good company.
Version 3.6.7

Absolutely stellar. When Apple's Calendar didn't send alarm notifications to my Google Calendar (making me miss appointments!), I switched to Busy Cal and that rectified things. That was a few years ago. I've been completely happy with this app and the few times I've had a tech support issue, I get an answer promptly.

very smart app
Version 3.6.2

The most convenient , powerful and reliable calendar application ever , the ability to create events and see your dates in day, weeks and month and most convenient way is the list view . The app integrates with to do lists and you can you use it from dock or menu bar . Adding icons and travel time is very nice touch from the developers seriously to the app and the most important part that you will not lose any notifications even if the app is not running . Great application that deserves a 5 star review

BusyCal has been my default calendar for years. It is very powerful, easy to use, and makes my busy life manageable. Sharing is simple and foolproof. The new dark mode implementation is awesome.
