Schedule assistant (Pro) Check your schedule, log overtime or change shifts in one sentence, typed or spoken. Every change waits for your confirmation and can be undone. You can also ask Siri what you work tomorrow. Alarm check See how every reminder in the next 48 hours will sound, and turn ordinary notifications into alarms with one tap. Schedule analysis Spot where your roster cuts into sleep, such as short breaks between shifts, runs of night shifts or too many days in a row, with suggestions. Today's shift and countdown See today's shift, start and end times, time until work or clock-out, and your next reminder. Shift calendar View morning, evening, night, off, and duty shifts directly on a monthly calendar. Cycle scheduling Create repeating patterns such as two days on and two days off. Preview and generate up to 365 days while choosing whether to replace or keep existing shifts. Excel and CSV import Preview and validate your existing roster before saving it.

Work shifts and lost track of which days you're on or off? Shift Alarm is the alarm clock that turns itself on for your work days and off for your days off, automatically, based on your schedule. Built for anyone working 12x36, 6x2, 6x4, or rotating shifts: nurses, security guards, factory workers, or any job with a schedule that keeps changing. WORKS WITH ANY SCHEDULE Set up your shift cycle once (6x2, 6x4, 12x36, or any other combination of work days and days off) and the app figures out on its own, every single day, whether today's alarm should be on or off. ROTATING SHIFTS (MORNING / AFTERNOON / NIGHT) Work in a factory with shifts that rotate between morning, afternoon, and night? Set each shift with its own alarm time and the app switches the alarm time automatically based on the day's shift. VISUAL CALENDAR See at a glance, on a monthly calendar, which days will have the alarm on and which are your days off, before the day even arrives. WORKS OFFLINE, NO ACCOUNT NEEDED No login, no internet required. Everything stays saved on your own phone. A REAL ALARM Rings for real, with sound and vibration, even with the phone locked, and if you restart the phone, alarms are rescheduled automatically.
