The stock alarm counts to seven. Your roster doesn't. OnDot Alarm is the iPhone alarm for people who don't work Monday to Friday. Alternating weeks, rotating shifts, public holidays — it schedules around your real life, so you stop editing alarms week to week. WHAT IT DOES • Alternating and custom weeks — one rest day this week, two the next, or any n-week cycle. Set it once. • Shift rotation — day, swing and night shifts, each with its own time. 2-on-2-off and 3-shift templates are built in. • Holiday aware — skips public holidays automatically and rings on make-up workdays, following official calendars bundled with the app. Pick your region, and keep your own custom rest days and workdays. • Clock — Timer, Stopwatch and World Clock in one tab; control timers from the Lock Screen and Dynamic Island. • Widgets — see the next alarm right on your Lock Screen and Home Screen, plus World Clock and, with Pro, Shift Week. • Sounds — a built-in set; Pro adds import of your own audio. FREE, WITH NO LIMIT Alternating weeks, shift rotations and holiday skip are free, with no cap on how many alarms you create. Upgrading never takes them away. • End dates — optionally end a shift rotation or calendar-date schedule on a chosen date. No end date is set by default. Browse past months in read-only mode. ONDOT PRO Pro also includes manual shift swaps and calendar-date scheduling: assign shifts directly to individual dates. Pro adds iCloud sync, so alarms, rotations and holiday settings stay consistent across your devices. Your data lives in your own iCloud account — there are no accounts to create, no ads, and no tracking. Pro also lets you import your own audio as alarm sounds and unlocks the Shift Week widget, with your shifts for the next 7 days at a glance. Pro also includes every Pro feature shipped later, and supports the continued development of this independent app. The yearly plan includes a 7-day free trial. Monthly, yearly and lifetime options are available; prices are shown in the app before you buy. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Manage or cancel anytime in Settings on your iPhone.

Shift Assistant
Read full descriptionHide full description
Shift Assistant schedules alarms from your roster—not another clock. Enter how you rotate and when a shift starts: 2-on-2-off, morning/swing/night, fixed weekdays, or a custom plant cycle. Wake, leave, and clock-out follow the shift; rest days stay quiet. Weekday schedules can follow national holidays: off on official rest days, still on for makeup workdays. After you change the roster, tap Update alarms. Overnight shifts stay on after midnight, and the clock-out alarm remains. Wake, leave, and clock-out can ring through Silent if you allow alarms; snooze shows a live countdown on the Lock Screen and Dynamic Island. Sleep is a regular notification—tap I’m already asleep if you went to bed early. Home screen widgets show leave countdown and your next shift. Mark plant rest, actual clock-out, or holidays on the calendar.
