An alarm for a specific date on iPhone.
On the day, at the time.
Pick a date and time and it rings on that exact day — the one-time alarm the built-in Clock app can't do. It even rings on silent.
Sound familiar?
The built-in iPhone alarm only lets you pick a time — not a specific date. CAlarm is a date-specific alarm: choose the day and time, and it rings exactly then.

What you can do with CAlarm

Rings on silent
Built on Apple's AlarmKit (iOS 26). It rings at alarm volume even in silent or Focus mode, so a muted phone won't make you miss it.

Frequently asked questions
Can I set an alarm for a specific date on iPhone?
Yes. With CAlarm you can set an alarm for a specific date and time on iOS — for example '15 Apr, 2:30 PM'.
How is it different from the built-in iOS alarm?
The built-in iOS alarm only lets you set a time, not a specific date. CAlarm lets you set both the date and the time, so it rings on that exact day.
Does it ring on silent mode?
Yes. CAlarm is built on Apple's AlarmKit (iOS 26), so it rings in silent and Focus mode. It uses the ringer and alarm volume, not the media volume, so you'll hear it even with media turned down.
Does it show on the Lock Screen?
Yes. Alarms and reminders appear full-screen on the Lock Screen and in Live Activity / Dynamic Island, so you notice at a glance.
Can I set recurring alarms by weekday?
Yes. You can pick multiple days — like every Monday and Thursday at 9:00 — for recurring alarms.
Can I get a pre-alert before an event?
Yes. You can set reminders before an event — 5 minutes, 10 minutes, 1 hour, 1 day, or 1 week before.
Can I change the alarm sound?
Yes. Choose from many sounds — classic, nature, music box, seasonal, and emergency tones.
Is CAlarm free?
Yes. It is free to download and the core features are free to use. Some features, such as removing ads, are available via in-app purchase.
