Kairos: Smart Alarm
Alarms that know your days off
Only for iPhone
Free
iPhone
Link your iPhone calendar to an alarm group and pick a word like “Vacation.” Then just add a “Vacation” event and alarms take that day off. Holidays are handled too.
Alarms that turn on and off with your schedule.
Ever forgot to turn off your alarm before a vacation, or to turn it back on for a weekend shift? Kairos checks your calendar and public holidays and decides each day whether to ring or rest. It works like the built-in Clock app, and takes care of the things you used to switch by hand.
■ Group your alarms
• Put several morning alarms in one group and set their repeat days at once.
• Turn a group off and every alarm in it goes quiet; turn it on and they’re back.
• Need just today off? Turn an alarm off and tap “Resume at Next Alarm.” It rings again from the next one.
■ Holidays off, automatically
• With “Skip Holidays” on, alarms stay quiet on public holidays, including observed holidays.
• Choose U.S. or Korean holidays. Set it with one switch for a group or for a single alarm.
• Holiday data updates automatically, without an app update.
■ Skip or ring by calendar events
• Link your iPhone calendar in an alarm group and choose words to rest on, like “Vacation” or “WFH.”
• From then on, a “Vacation” event is all it takes to skip that day’s alarms.
• Choose a word to ring on, like “Weekend shift,” and alarms ring even on weekends.
• Event titles are only matched on your device. They are never stored or sent.
■ Adjust any day on the calendar
• Tap a date in a group’s calendar to skip or ring just that day.
• The Schedule tab shows which alarms ring each day and why the others are off.
■ Rings like a real alarm
• Built on iPhone alarms (AlarmKit), so it rings in Silent mode and during a Focus.
• Pick a snooze length from 1 to 15 minutes and see the countdown on the Lock Screen.
• Ten original alarm sounds, plus a “Tomorrow’s Alarms” note the night before.
• Awake before your alarm? Touch and hold the heads-up notification to turn that day’s alarm off (turn it on in Settings).
■ Widgets at a glance
• See your next alarm on the Lock Screen and Home Screen.
• If tomorrow is a day off, the widget shows why and when alarms ring again.
• The medium Home Screen widget shows the next few days, including days off.
■ English and Korean
• Kairos follows your iPhone language, or pick English or Korean in Settings.
■ Privacy
• No sign-up or login. All settings stay on your device.
• No data is collected or tracked.
