## What is Shift Rail?

An ad-free shift calendar that shows today's shift the moment you open it.

ROSTER
Pick your rotation and tap which shift today is — the whole month fills in, no start date to work out. Start from 2-shift, 3-shift, day–night–off–rest, 24-hour duty or weekday presets, or build your own rotation of 2 to 28 days.
• A month calendar with day, evening, night, duty, off and rest days in their own colors, starting on your device's first weekday
• Tap a date to change just that day: leave, a swapped shift, cover
• Monthly totals, such as D 10 · N 10 · Off 5 · R 6
• Today, tomorrow and your next shift at the top of the app
Saving, viewing and changing days in a roster works without Pro.

ALARMS FROM YOUR ROSTER (PRO)
Tap "Set alarms from this roster" and Shift Rail sets each date's alarms for that day's shift, 28 days ahead. The roster is the source: change a day and that day's alarms change too. When fewer than seven days are left, opening the app quietly tops them up.

SHARE THE MONTH AS AN IMAGE (PRO)
Send an image with the roster's name, month, calendar and totals through Messages, Photos and more. Try it three times without Pro.

ALARM ROUTINES FOR A SHIFTED DAY
• Save separate routines for workdays, workouts, weekends, or shifts
• Move a routine from 60 minutes earlier to 90 minutes later, comparing every time before applying
• Set one alarm to a target time and preview the whole routine moving with it
• Choose the system sound or one of four original Shift Rail sounds

CAREFUL BY DESIGN
Shift Rail uses Apple's AlarmKit framework to schedule its alarms. It checks the resulting schedule after a change. If the schedule needs attention, the app shows a repair state instead of claiming that everything worked.

OPTIONAL PRO
A one-time Pro purchase sets alarms from your roster, shares the month as an image, and saves named target-time plans such as Early shift or School run. There is no subscription. All original alarm features and rosters work without Pro, and rosters with alarms set and saved plans stay readable, usable and deletable if Pro access ends.

IMPORTANT
No ads, no sign-in, no server. Shift Rail manages only alarms created inside Shift Rail; it does not change alarms in Apple's Clock app. Alarm access is required. Roster alarms are scheduled up to 80 at a time, so a roster with many alarms covers fewer days. Vibration and volume follow iPhone system settings, and delivery remains subject to iOS and device settings. Rosters and routines stay on this iPhone.

English and Korean are included.
