I have really been enjoying the v3 update to Fantastical and plan on subscribing after the free trial1. The iOS version FINALLY has feature parity with the Mac version, which means the iOS version supports calendar sets, Travel Time, and time to leave notifications. I like that Fantastical can now send new event notifications for shared iCloud calendars. Fantastical is no longer limited to accounts configured on-device, you can sign into Todoist, Google, Exchange, and Office365 accounts (to name a few).
Fantastical moving to a subscription has been discussed many other places. I use Fantastical so much that the subscription is worth it.↩
