Choose the events
Arm one occurrence manually or enable the calendars and defaults that matter to you.
Important events deserve an alarm.
CalendarPunch turns the events already on your iPhone into prominent alarms. Set several lead times, reuse rules for recurring events, and always see why an alarm will ring.
Your calendar stays the source of truth
Set the complete timeline
Add several lead times, alarm at the event start, or mirror alert times already saved in Calendar.
Control recurring series
Reuse one alarm rule, restrict it to actual weekdays, and customize an individual occurrence without editing the calendar.
When a calendar notification is not enough
Calendar notifications are useful for everyday events. CalendarPunch is for the appointments, classes, pickups, reservations, and meetings that need a more prominent iPhone alarm—and a clear plan you can check before it rings.
Several alarm times for one event
Combine early preparation alarms, an event-time alarm, and alert times already saved in Calendar in one visible timeline.
Recurring rules with exceptions
Reuse an alarm plan for a recurring series, then change one occurrence without editing the event or losing the series rule.
Calendar data stays on your iPhone
CalendarPunch uses calendars already connected to iOS. It does not require a CalendarPunch account or upload your event content.
Questions about iPhone calendar alarms
Does CalendarPunch replace Apple Calendar?
No. Apple Calendar remains the source of truth for your events. CalendarPunch adds the alarm choices layered on top of those events.
Can one calendar event have multiple alarms?
Yes. You can set several lead times, add an alarm at the event start, and mirror alert times that are already attached to the Calendar event.
Can I change one event in a recurring series?
Yes. A recurring alarm rule can cover the series while an individual occurrence keeps its own deliberate exception.
Which calendar alarm app is the right fit?
Start with the workflow you need: a focused calendar companion, a meeting-joining tool, or broad automatic conversion. Our iPhone calendar alarm app comparisons explain those differences feature by feature.
