Shift-work alarm · iPhone
The stock alarm counts to seven. Your roster doesn’t.
Alternating weeks, rotating shifts, public holidays — OnDot Alarm schedules around your real life, so you never edit alarms week to week.
Free download · Core scheduling always free · Pro includes a 7-day trial
CYCLE
Your alarm should follow your roster.
- 07
The stock alarm
Repeats by weekday only — a seven-day loop where weekends all ring or all stay silent.
- 14
Alternating weeks
A 14-day cycle: one rest day, then two. Set it once for the whole year.
- 04
2 on, 2 off
A 4-day cycle that ignores the weekday and follows your shifts.
- 08
3-shift rotation
Day, swing and night, each at its own time — eight days per loop.
ROSTER TAPE · LIVE
Your next alarm isn’t tomorrow at the same time
A repeating alarm has exactly one model: a seven-day mask. Two-on-two-off runs on four days, alternating weeks on fourteen, rotations on more — they all lay out on the same tape.

FAQ
Questions, answered
How is this different from the iPhone’s built-in alarm?
The stock alarm only repeats by weekday. OnDot Alarm expresses alternating weeks, arbitrary n-week cycles and shift rotations — and skips public holidays while ringing on make-up workdays.
Where does the holiday data come from?
Official public-holiday calendars are bundled with the app, and new years are filled in from the cloud once they are announced — no app update needed. You pick your region and can maintain custom rest days and workdays.
Free vs Pro — what’s the difference?
Alternating weeks, shift rotations and holiday skip are all free, with no limit. Pro adds iCloud sync, every Pro feature we ship next, and support for this indie app’s continued development — the yearly plan includes a 7-day free trial.
Does my roster survive a new phone?
With Pro, your roster syncs over iCloud. Sign in with the same Apple Account on the new device and it’s back.
How do I cancel?
Anytime in iPhone Settings → App Store subscriptions. You keep Pro until the current period ends — not a day is wasted.
Does my data get uploaded?
No. Your roster lives on your device and in your own iCloud. No accounts, no ads, no tracking.
