One-time alarm
Set '15 Apr, 2:30 PM' to ring once on that specific date. You'll never forget the day of an event.
All features of the date-specific alarm
From date-and-time alarms to pre-alerts, schedules, calendar and widgets — here is everything CAlarm can do.
Download on theApp StoreDate-specific alarms
The built-in iOS alarm only lets you set a time. CAlarm lets you set both a date and a time, so it rings on the exact day.
Weekly repeat
Combine any days Mon–Sun. Recurring alarms like every Monday and Thursday at 9:00 are easy to set up.
Alarms linked to schedules
Create alarms straight from a schedule you've added, and link several alarms to a single schedule.
Swipe to delete / duplicate
Long-press to duplicate an existing alarm, swipe to delete (with undo). Toggle recurring alarms on and off in one tap.
Reliable alarms with AlarmKit
CAlarm is built on Apple's AlarmKit (iOS 26). It uses the same mechanism as the built-in Clock app, so alarms arrive more reliably than notification-based apps.
Rings at ringer / alarm volume
It rings at the ringer and alarm volume, not the media volume. Even with media turned down, the alarm rings loud and clear.
Rings on silent
It rings even in silent, Do Not Disturb, or Focus mode, so it won't go quiet and slip past you.
Full-screen on the Lock Screen
Alarms and reminders appear full-screen on the Lock Screen, so you notice the moment you glance at your phone.
Pre-alerts
A heads-up before the main event, so you don't lose time to prepare or travel.
9 pre-alert options
Choose from 5, 10, 15, 30 minutes, 1 or 2 hours, 1 or 2 days, or 1 week before.
Attach notes & URLs
Add a title, note, or URL to a reminder and jump straight to what you need from the notification.
Rich alarm sounds & snooze
Pick from more than 30 sounds to match the moment.
A wide range of sounds
Classic (buzzer, digital, doorbell…), nature (birds, forest, river), music box, songs, seasonal, and emergency tones (including Japan's disaster-alert sound) — plus 'none'.
Long snooze too
Snooze intervals from none, 1–30 min, 45 and 60 min, up to 2–12 hours — from short anti-oversleep gaps to a 12-hour long snooze.
Schedule management & templates
Manage the events themselves, not just alarms — and save your common patterns as templates.
Schedules
Set a title, start/end time, note, URL, and color. Link notifying reminders or silent milestones to each schedule.
Schedule templates
Save recurring schedule patterns as templates and create them on any selected day in one tap.
Templates for items too
Not just schedules — alarms, reminders, and milestones can each be saved as templates, and reordered by drag & drop.
See it all on the calendar
A month view shows your schedules and alarms at a glance.
Month view
Scroll infinitely between months. Day cells show color markers for your registered schedules.
