Reviewed July 27, 2026
Why choose CalendarPunch?
CalendarPunch is built for people who already trust their calendar but do not trust an ordinary notification to get their attention. It does not try to own the event. It owns the alarm choices layered on top: which times should ring, whether those times apply once or recur, and whether an individual occurrence should follow the usual rule.
Calendar-service neutral
Use iCloud, Google, Outlook, Exchange, or another calendar that appears in Apple Calendar.
Built for life beyond assignments
The same alarm controls work for appointments, work meetings, family events, and personal routines.
Richer recurring behavior
Create series rules, weekday constraints, and reversible one-occurrence exceptions.

Automation without hidden behavior
CalendarPunch applies defaults and rules to synchronized EventKit events without requiring a service-specific workflow. CalendarPunch also retains saved settings when an alarm is turned off, making “disabled” different from “forgotten.” A global pause removes desired alarms without deleting the plan that should return later.
A better model for recurring events
CalendarPunch supports reusable recurring rules and individual occurrence exceptions, useful beyond course deadlines. CalendarPunch derives occurrences from the real calendar, so alarm rules never invent weekdays, ignore exceptions, or pretend to own the event’s recurrence.
