Shift Alarm reads the events in your device calendar, automatically detects each day's shift, rings your alarm for day shifts, night shifts and more, and skips your days off automatically — a wake-up app built for shift workers.

■ Who it's for
- Irregular schedules: day, night, early or late shifts
- You forget to turn off the alarm and wake up on your day off
- You don't want it to ring the morning after a night shift
- You're tired of resetting the alarm every night to match tomorrow's plan

■ How automatic detection works
1. It detects the day's shift from your calendar events (title and more)
2. It automatically decides "ring or skip" using the conditions you set
You build conditions by combining keywords, weekdays and holidays, so setups like "ring at 16:30 only on night-shift days" or "stay silent on weekends and holidays" work exactly the way you want.

■ Key features
- Rings according to your shift type and skips days off and paid leave automatically
- Per-day manual override: ring or skip "just for tomorrow" in one tap
- Group multiple alarms to manage their conditions together
- Snooze (set the interval and maximum count)
- A notification lets you know on mornings it skips (can be turned off)
- Review the decision history in a log
- Light / dark / system-linked theme

■ To make sure it rings
It supports exact alarms and full-screen display so it goes off on time even while sleeping or in silent mode, and it automatically reschedules your alarms after the device restarts.
