Another Winning Version!

This calendar app is the cleanest and quickestt available. If you liked the early version(s) of Fantastical, this is for you. In this version they add more views and a cleaner interface, and yet retain the simplicty and speed. I SO WISH I could also use this on my Windows PCs in a simlar fashion - it just works quick and easy. Natural language input, varied views, quick setup, etc. So good!

Just enough calendar & reminders -- right where you need 'em

Replace the clock on your menubar with this app, and suddenly reminders and calendars don't require so much work anymore. Convenient, quick and out of the way -- just as it should be.

Keeps crashing from menu bar

This was working great until a couple days ago, and now whenever I click on the menu bar, it crashes out. Sent in the details. Hope this is resolved soon.

UPDATE: Still crashing. Have tried everything. Deleting preferences. What did I pay for? Having buyer remorse.

Developer Response ,

This issue (Mojave) was fixed in v2.3.8!
