"Wait — that was today?" By the time you realise, it's over. The online lesson. The dentist. Your kid's school visit. The form that had to be in by Friday. It was in your calendar the whole time. The notification came and went while your phone was face down on the table. KeyAlarm is for the appointments you cannot miss. ■ Add the keyword once. That's it. Type "lesson" and set it for 30 minutes before. From then on, every event with "lesson" in the title gets a real alarm — this week, next month, forever. You never set another one by hand. Three kids and a different activity every day? One rule covers all of them. ■ A real alarm, not a notification KeyAlarm uses the same system alarms as the built-in Clock app. It rings on silent. It rings in Focus. It keeps ringing until you reach over and stop it. That is the whole point — a notification you can sleep through is not a reminder. ■ One to get ready. One to leave. A single keyword can ring more than once. Thirty minutes before to start getting ready, five minutes before to actually walk out the door. Two alarms, one rule. ■ Or take a whole calendar Have a calendar just for your kid's activities? Skip keywords entirely and set an alarm for every event in it, whatever it says. ■ See that it's set Open the Scheduled tab and every upcoming alarm is right there with its time. No wondering whether it worked. Don't need one of them? Swipe it away, or tap the × on the Lock Screen countdown. ■ Your calendar stays yours KeyAlarm has no servers. Your events are read on your iPhone and never leave it. No account, no sign-in, nothing to opt out of. ■ Free for 30 days, then a one-time purchase No subscription. Pay once, keep it. And if the trial runs out, alarms you already set keep ringing — only new ones stop being added. An app like this should never go quiet because of billing. Requires iOS 26 or later. Works with any calendar your iPhone syncs, including Google, Outlook, and iCloud. Website and user guide: https://ltng.jp/apps/keyalarm/en
