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. No more forgetting the alarm on during your day off or off during a work day. Set it up once and let Shift Alarm handle the rest. Free 15 day trial. After that, choose an annual subscription or a one time purchase (lifetime). Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
