Alarum

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

That sounds like a low bar. It isn't. Until iOS 26 no third-party app could do it, so every alarm app on the App Store worked around the system instead of with it. Alarum is built on Apple's AlarmKit, which means the system itself is ringing, not a background-audio trick.

• Rings on silent, in Focus, and at zero volume
• Your own sounds — import any audio file
• Snooze from one minute to twelve hours
• Test any alarm before you trust it with your morning
• No accounts, no tracking, no paywall

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