Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
Calendars by Readdle combines calendar management, task planning, reminders, and scheduling tools for people using iPhone, iPad, Mac, or Apple Watch. It brings connected calendars into a unified view, supports two-way synchronization, and adds recurring events, color coding, attendee invitations, and video-call details. Apple users who want events and tasks in one interface are the clearest fit, especially when they manage more than one calendar account.
Pricing is structured around a basic Free plan, a Calendars PRO Monthly subscription, a Calendars PRO Annual plan, and a Calendars Lifetime purchase. The Free plan provides a basic calendar, while the paid tiers add premium calendar and planner features. The annual plan costs $19.99 per year and includes access across Mac, iPhone, iPad, and Apple Watch, along with Planner and tasks, multiple accounts, recurring events, natural-language input, and reminders. The lifetime option costs $59.99 one time and includes lifetime access and Family Sharing. A 7-day free trial is also available.
Its strongest advantage is platform and ecosystem fit. Calendars by Readdle connects with Google Calendar, iCloud Calendar, Exchange Calendar, Outlook Calendar, Apple Reminders, Google Tasks, Zoom, GoToMeeting, Apple Maps, and Google Maps. Drag-and-drop rescheduling and task time blocking make it more than a read-only calendar, while natural-language input can speed up event and task creation. The trade-off is its Apple-only coverage: users who need Android or web access should choose another calendar app. It also does not provide a scheduling-link feature, so it is better suited to personal planning and shared calendars than booking-page workflows.
