Questions people actually ask
Does the alarm ring when my iPhone is on Silent or in a Focus mode?
Yes. Larm uses Apple's AlarmKit framework (iOS 26), so alarms are scheduled by the system itself and ring loud and full-screen even with the Silent switch on, a Focus (like Sleep) enabled, or the app closed.
Is Larm really free? What does the one-time purchase unlock?
The core app is free: alarms with repeat and snooze, all alarm sounds, sleep mode and the sleep log. Larm Pro is a single one-time lifetime purchase (not a subscription) that unlocks fall-asleep nature sounds and 30-day statistics. No ads, no subscriptions anywhere.
Does Larm work offline? Do I need an account?
Fully offline. No account, no sign-in, no cloud — all data stays on your iPhone.
Does Larm track sleep phases with the microphone or sensors?
No — and that's deliberate. You tap "going to sleep" and Larm logs your time in bed. No microphone listening, no motion sensing, no invented "deep sleep" numbers. Honest data only.
What iPhone do I need?
iOS 26 or later — the reliable alarm is built on Apple's AlarmKit framework introduced in iOS 26.
