What is Calendars by Readdle?

Calendars is Readdle's calendar and planner app for Apple devices. It brings Google, iCloud, Outlook and Exchange calendars into one view, shows tasks from Apple Reminders or Google Tasks next to events, and accepts events typed in plain language. The app is free to download with a basic calendar; most of the planner features sit behind the Calendars PRO subscription, sold through the App Store.

Calendars by Readdle has a free plan. Paid plans start at $19.99 per year, or $3.99 per month (US App Store in-app purchases). See every plan

Good for

  • People on iPhone, iPad and Mac who want events and tasks in one planner
  • Google Workspace users who book rooms and check coworkers' schedules
  • Anyone who prefers typing events in plain language

Worth knowing

  • Apple devices only: the App Store listing covers iPhone, iPad, Mac, Apple Watch and Apple Vision. No Windows, Android or web version is listed.
  • The free plan is a basic calendar; tasks, multiple accounts, recurring events, natural language input and weather need Calendars PRO.
  • Free users get one alert per event, while PRO allows up to five.
  • There is no Mac-only purchase: PRO is a single cross-platform subscription, and Readdle says its price varies by region and local taxes.
