Alternating & custom weeks
One rest day this week, two the next — or any n-week cycle. Set once, done for the year.

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.

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 updated with releases. 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.
