## What is Kairos?

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.

### 5/5 — 개발자님

*2026-10-18*

정말 갤럭시에서 오고 적응 안되는게 알람 그룹화였는데 만들어주셔서 감사합니다
한가지 추가해주셨우면 하는게 있는데
소리없이 진동으로만 울리는 알림이 있으면 좋겠습니다

**Developer response:** 안녕하세요. 카이로스 개발자입니다.
현재 사용하는 방식이 아이폰 시계 앱에서 지원하는 알람과 동일한 기능을 활용하여 앱 기능을 제공하고 있습니다.
소리없이 진동만 울리는 방식을 알아보니, 현재까지는 해당 기능을 일반 개발자에게는 지원을 하지 않아서 어떤 방법으로 해결이 가능할지 확인 중에 있습니다.

2026-10-22 추가 답변
1.4.0 버전에서 알람 사운드에서 '없음'을 선택하시면 소리 없이 진동만 울리는 알람을 설정하실 수 있습니다. 금주 내에 업데이트 될 예정입니다.

좋은 의견 주셔서 감사하며, 불편한 사항이 있으실 경우 언제든지 문의 주시기 바랍니다.
감사합니다.

### 5/5 — 기능 요청

*2026-10-18*

1. 오늘만 쉬기 기능이 있다고 들었는데 동작하지 않습니다.
그룹을 끌 때 다음 알람부터 켜기라는 알림창 뜨지 않아요
2. 일정 탭에 알람 현황들이 나오는데 해당 화면에서 특정 알람이.울리지 않도록 삭제/취소 기능이 있으면 좋을 것 같아요
3. 무조건 요일 반복으로 동작하는게 아이폰 시스템인 것을 알지만, 혹시 특정 일 하루에만 미리 알람을 설정 할 수 있는지 궁금합니다

**Developer response:** 안녕하세요. 카이로스 개발자입니다.

1. 오늘만 쉬기 기능은 알람이 설정된 당일 앱 내에서 알람 토글을 끄게 되면 다음 일정부터 다시 켜도록 버튼이 안내되도록 되어있습니다.
2. 일정 탭에서 특정 알람에 대하여 삭제하거나 취소하는 기능은 주신 의견을 반영해서 빠른 시일 내에 지원하도록 하겠습니다.
3. 그룹을 만들고 해당 그룹에서 특정 날짜를 지정하시면 원하시는 날짜에만 울리는 알람을 만드실 수 있습니다.

감사합니다.

### 3/5 — 알람 진동

*2026-10-12*

알람에 진동은 추가가 안되나요?
진동으로 알람을 받고 싶은 경우도 있어서요

**Developer response:** 안녕하세요. 카이로스 개발자입니다.
현재 아이폰에서 제공하는 시계 앱의 알람과 동일한 방식으로 제공하고 있어, 알람이 울릴 시 진동도 같이 오게 됩니다. 혹시 원하시는 방식이 진동으로만 울리는 형태를 이야기하시는 것일까요?
필요로 하시는 방법을 이야기해주시면, 추후 개발 계획에 먼저 반영하여 진행하도록 하겠습니다.

추가 피드백은 앱 내 지원 링크를 통해 전달 주시면 감사하겠습니다.

감사합니다.

### 5/5 — 기본 알람 앱보다 편해요

*2026-10-11*

비정기적으로 근무를 해서 매일 다르게 알람 설정하는게 번거로웠는데 이 앱 덕분에 훨씬 편해졌습니다. 알람 앱을 이거로 정착할 것 같아요.

**Developer response:** 안녕하세요. 카이로스 개발자입니다.
편해지셨다니 기분이 좋습니다. 앞으로도 많은 사용 부탁드리며, 불편하신 사항이 있다면 언제든 피드백 부탁드립니다. 감사합니다.
