Alarum: Loud Alarm Clock

Alarum is an alarm clock that actually rings — through the silent switch, through Do Not Disturb, and through every Focus mode.

WHAT THE BUILT-IN CLOCK DOESN'T DO

• Your own sounds. Import any audio file and wake up to it. • Test this alarm. Fire the real alarm, with its real sound, seconds from now — so you know it works before you rely on it. • Snooze from one minute to twelve hours, set per alarm. • Bedside mode. A dimmed nightstand clock that stays awake. • A countdown timer that rings just as loudly. • Choose the typeface and the accent colour.

BUILT ON ALARMKIT

Alarum uses Apple's own alarm system, so iOS itself schedules the alarm — not a background-audio trick of the kind alarm apps had to rely on before iOS 26.

NO PAYWALL

Everything above is free. There is one optional purchase in Settings that unlocks nothing at all — it exists only for people who would like to say thanks, and the app never asks.

NOTHING LEAVES YOUR PHONE

No account. No sign-in. No analytics. No third-party services. Your alarms are stored on your device and nowhere else.
