A shift-rotation calendar that gets 12-hour and DuPont overtime right, because most don't. Pick a rotation pattern — including 12-hour, DuPont, or your own custom cycle — set the day it starts, and ShiftRoster projects every month forward: your shift, your rest days, and public holidays for your German state (Bundesland), computed on your device with no yearly update needed. Why this app exists: shift-roster apps compute overtime by counting shift days, so a 12-hour rotation with 16 rest days a month shows overtime that makes no sense. ShiftRoster computes your target from your actual contract hours, so working a rest day adds real overtime and a rest day never inflates your target. Vacation and sick days are credited correctly. Your running hours balance (Stundenkonto) carries over month to month and is always something you can check against your own contract. FEATURES • Rotation patterns — 8-hour, 12-hour and DuPont templates, plus a custom cycle editor for any pattern not on the list • Month calendar — your shifts, rest days and public holidays at a glance • Hours & overtime — target vs. worked, computed correctly for 12-hour rotations, with vacation, sick and training days credited • Public holidays for all 16 German states (Bundesländer), calculated on your device with a local Easter-based algorithm — no network fetch, no yearly content update • A home-screen and Lock Screen widget showing today's and tomorrow's shift, built to keep working after iOS updates Unlock "Full roster" once, for EUR 5.99 / USD 5.99, to add: • Pay estimate — enter your hourly rate and night/Sunday/holiday supplement percentages for an estimated gross per period (not a payslip, not tax advice) • Calendar export — send your shifts to the iOS Calendar • CSV month sheet — a shareable hours-and-pay spreadsheet for payroll disputes • iCloud sync — your roster on every device you own Everything else — the full rotation calendar for any month, hours and overtime, one Bundesland's holidays, and the widget — is free, no trial, no time limit. This is a one-time purchase. No subscription, no ads. No account. No tracking. Your data stays on your device. ShiftRoster gives no legal, tax or payroll advice — the pay estimate is arithmetic on the rate and percentages you enter, so you can sanity-check your own payslip.
