ONE NOTIFICATION PER ALARM An alarm used to arrive as several notifications — one per escalation level, plus a duplicate. It now appears as a single notification that updates as the alarm escalates, and turns into a short summary when it ends. THE REAL REASON, EVEN WHEN THE APP IS CLOSED Alarm notifications now show what your Mac actually detected instead of a generic sentence, even if the app has been closed. KNOW WHEN YOUR MAC DISARMS If your Mac switches to Home because your iPhone came back home, you get a notification with a one-tap "Arm Guard" in case it wasn't you. CLEARER WORDING "Everyone's Home" is now "Someone's Home", and device counts say what they are: familiar devices nearby.

The alarm path has been rebuilt. If you only read one line: alerts now arrive even when the app has been swiped away. ALARMS ACTUALLY REACH YOU Alerts previously relied on a silent background wake, which iOS delays under Low Power Mode, throttles unpredictably, and does not deliver at all if you have force-quit the app. For a security app that was the single worst failure mode. Alarms now arrive as a real alerting notification with sound, carrying the reason with them. "IT'S ME" FROM YOUR WRIST WORKS Dismissing an alarm from the watch used to clear only the watch screen. The alarm kept sounding at home and nobody told you. The command now travels all the way through. NOTIFICATION BUTTONS WORK Arm and Disarm from a notification previously changed the label on your screen without sending anything. They now send the real command and the change sticks. SIRI TELLS THE TRUTH "Arm", "Disarm" and "Dismiss alarm" reported success no matter what happened. They now send a real command, and if it cannot be delivered Siri says so instead of pretending. COMMANDS ARE NO LONGER LOST Two commands sent close together — say switching mode and then dismissing an alarm — could overwrite each other and one would vanish. Commands are now queued and each one is confirmed before it is cleared. DISMISSING AN ALARM REMOTELY WORKS Dismissing from the phone was silently doing nothing on the alarm record itself. Fixed. ACKNOWLEDGING AN ALARM IS VISIBLE Tapping "I'm checking" now puts the alarm into an Investigating state you can see, instead of only pausing the countdown with no visible change. BACKGROUND REFRESH Status is refreshed periodically in the background, so what you see when you open the app is current rather than however stale it was when you last closed it. MORE RELIABLE CONNECTION Push registration retries with sensible backoff instead of hammering iCloud, sync no longer treats a network failure as success, and the status you see is a single consistent value rather than three inconsistent spellings of it. FEWER FALSE ALARMS A familiar device could be mistaken for an unknown one after its Bluetooth address rotated. Recognition is much more reliable now. BATTERY Duplicate network fetches on each notification were removed, and retries now back off instead of repeating every thirty seconds.
