Shift Calendar Alarm
Read full descriptionHide full description
If your shifts move around from week to week, you probably spend more time than you'd like resetting alarms and double-checking them before an early start. Shift Calendar Alarm takes care of that. Put your shifts on the calendar, and the app sets your iPhone alarms for the next 60 days, then updates them on its own whenever your schedule changes. Start by saving the shifts you work most, like early, late, night, or on-call, as Shift Types. Each one can have up to three alarms, on the day itself or the evening before, which helps when a very early start means you want a heads-up the night before. Then tap dates on the calendar to schedule them, with more than one shift on the same day if that's how your week looks. The calendar and shared images show the month’s scheduled day count, counting each date once, and dim days outside the month. Even if your schedule is never quite the same, there's often a stretch that repeats, and Patterns save you from tapping it in again and again. Line up those shifts in order, say two early days, two nights, and two days off, pick a start date, and the whole stretch lands on your calendar at once. Your first pattern is free. Tap any date to see that day's shifts, alarms, and notes together, and a small dot on the calendar tells you which days have notes. A note can stay with its Shift Type or be rewritten for a single day. If you don't need one particular alarm, say on a day you've swapped with a coworker, you can skip just that one without changing the shift itself. Scheduled Alarms shows everything that's about to ring, and Alarm Health checks permissions and sync status and points out anything that needs attention. You only need to rebuild alarms by hand if sync runs into a problem. The Home Screen widget keeps today's and tomorrow's shifts and alarms in view, and a 9:30 p.m. reminder tells you what tomorrow looks like before you go to bed. You'll also find Silent Alarm Mode, calendar images you can share with family or coworkers, iCloud sync, language settings, and Light and Dark Mode. The free version includes 3 Shift Types, 1 pattern, and 8 scheduled shifts. Premium removes those limits. Shift Calendar Alarm is made for keeping track of your own shifts and alarms. It isn't a team scheduling, payroll, or HR tool. Highlights: - Calendar-based shift planning - Multiple shifts on the same day - Date details and notes - One-time alarm skips - Up to three same-day or previous-day alarms per Shift Type - Automatic sync of native iPhone alarms for the next 60 days - Scheduled Alarms, manual rebuild, and Alarm Health - Home Screen widget for today’s and tomorrow’s shifts and alarms - 9:30 p.m. reminder with tomorrow’s schedule - Silent Alarm Mode, calendar image sharing, and iCloud sync - Multi-day Patterns, with your first pattern free - Free: 3 Shift Types, 1 pattern, and 8 scheduled shifts, with Premium unlimited Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
