Know what your paycheck should be, before it arrives. Most hours trackers fall apart on hospital schedules: overnight shifts split in two, night differentials forgotten, weekly overtime counted wrong. This app is built for 12-hour shift workers, so the hard parts are automatic. CLOCK IT OR LOG IT • One-tap clock in / clock out, or log a shift in seconds • Overnight shifts count as one shift, on the day you clocked in, the way payroll does it • Repeating rotations (like 3-on-4-off) fill your calendar in one tap PAY THAT MATCHES YOUR STUB • Night and weekend differentials apply themselves to the right hours • Per-shift overtime (after 12h) and weekly overtime (after 40h), split correctly • See each pay period's total build shift by shift YOUR TIMESHEET, YOUR PROOF • Export any period as CSV or a clean PDF timesheet • Back up everything to a file you control PRIVATE BY DESIGN • No account. Your shift and pay data never leave your phone. SUBSCRIPTION Try everything free for 7 days. After that, TwelveHr Pro keeps every feature unlocked. No tiers, no locked buttons.
