Calendars by Readdle review

Calendars by Readdle sits between Apple Calendar and Fantastical. Its App Store listing describes an all-in-one calendar, task manager, daily planner and habit tracker that runs on Mac, iPhone, iPad and Apple Watch and syncs with Google Calendar and iCloud. You get daily, weekly and monthly views, a built-in agenda planner, natural language entry for events and to-dos, color coding and widgets, and you can join Zoom, Google Meet or GoToMeeting calls straight from an event. Readdle has also added routines, habit tracking and a guided productivity course, which suits people who want one app for planning the day rather than only reading a schedule. Calendars PRO is listed at $3.99 a month on the US App Store, cheaper than Fantastical Premium's monthly price. The drawbacks are mostly about clarity: the in-app purchase list shows several yearly prices and separate add-ons such as recurring events, so it is hard to tell from the listing exactly what each tier includes. It also lists no quarter or year view.
