KeyAlarm turns calendar events into real alarms that ring through Silent mode and Focus — built on iOS 26 AlarmKit, now in 8 languages —
Lightning LLC (Tokyo) today announced that KeyAlarm, an iPhone app built on Apple's new AlarmKit framework in iOS 26, is now available worldwide in eight languages: English, Japanese, Simplified and Traditional Chinese, Korean, Spanish, German and French. It is one of the first apps to ship on AlarmKit.
01The problem: notifications are just banners
Calendar notifications are easy to miss. They are silenced by the mute switch, hidden by Focus modes, and dismissed with a single swipe. "It was in my calendar, I just didn't see the notification" is one of the most common ways people miss a lesson, a meeting or a train.
iOS 26 introduced AlarmKit, which for the first time lets third-party apps schedule alarms with the same standing as the built-in Clock app: full-screen, audible through Silent mode and Focus, and ringing until the user stops them.
02How KeyAlarm works
- Register a keyword once. Add "Piano" and every calendar event whose title contains "Piano" automatically gets an alarm. No per-event setup.
- Real alarms, not notifications. They ring through Silent mode and Focus and keep ringing until stopped. Snooze uses the system alarm UI.
- Several lead times per keyword. For example 30 minutes before to get ready and 5 minutes before to leave.
- Whole calendars, too. A "Kids" or "Work" calendar can be turned into alarms in one step.
- Nothing leaves the phone. No server, no account. App Store privacy label: "Data Not Collected".
