What's New in CalAlarm

1.4

September 17, 2026

You can now set an alarm up to 12 hours before an event (the old limit was one hour). • Separate hours and minutes wheels, so a long lead time is still quick to pick — and still to the minute • One-tap presets for 5, 10 and 30 minutes, and 1 and 2 hours • When the alarm lands on the previous day, the date is shown alongside the time

Cal Alarm needs more pre-time delay

I have a 45 minute commute, so being able to set a 2 hour lead would be super important, one hour makes the app useless, because I can’t get ready to leave in 15 minutes. The application is absolutely perfect now due to the update, in its simplicity and effectiveness. I’ve recommend it to all of my colleagues.

Response from developer

Thanks for taking the time to explain the problem — a 45-minute commute is exactly the case the old one-hour cap got wrong. Version 1.4 is out now, and lead times go up to 12 hours before an event, set to the minute. There are one-tap presets for 5, 10 and 30 minutes and for 1 and 2 hours. You can set it per event by tapping the alarm time under any event, or change the default in Settings → Default alarm timing. Hope the 2-hour lead works the way you need it to now.

FAQ

How does CalAlarm ensure alarms ring through Silent and Focus modes?

CalAlarm utilizes the same alarm engine as the iOS Clock app. This system-level integration allows it to bypass Silent mode, Do Not Disturb, and Focus modes, ensuring your important event alarms are heard.

What happens if a calendar event's time is changed?

If a calendar event's time is moved or the event is deleted, CalAlarm automatically updates or removes the corresponding alarm. Your calendar remains the single source of truth, keeping your alarms perfectly in sync.

Can I set different lead times for alarms?

Yes, CalAlarm offers flexible lead times. You can set a global default lead time for all alarms, and then override it on a per-event basis for specific needs, such as setting a dentist appointment alarm 30 minutes early.

Does CalAlarm have ads?

No, CalAlarm is ad-free. The app's privacy-first approach means it does not contain tracking or advertisements, ensuring an uninterrupted user experience.

What is the price of CalAlarm?

CalAlarm is a paid application priced at $9.99. This is a one-time purchase, aligning with the app's focus on simple, pay-once tools.

What devices is CalAlarm compatible with?

CalAlarm requires an iPhone running iOS 26 or later. It is designed to leverage the system's Clock-grade alarm engine for optimal performance on supported devices.
