I fully understand the needs and wants of developers to generate income. But I reverted back to the MacOS calendar, because the cost of BusyCal with its 18 month licenses is not justifiable by the features and the link to BusyContracts.

Works fine. I bought it mainly because it looks better that Apple's calendar. Now the upgrade costs are too high and frequent for me. A regular + pro licences could have done it for me, not shelling out ~$30 quite often.

Great app but it constantly quits. I'm just going to use Calendar 366 (less features) but more reliable.

Still using version 3.12 and very happy with it. However with new subscription thing I will not upgrade. When 3.12 stops working I wll switch unless pricing is fixed. For non-business personnal use it is great but way too costly (a restricted version could be interesting, too).
