ShiftClock: Hours & Pay

Time clock & overtime tracker. Track work hours, OT/DT pay, shifts & per diem. Built for hourly workers, tradespeople, and union members.

ShiftClock is a native iOS app for tracking work hours and calculating pay with full support for overtime, double time, union benefits, and payroll verification. Built with SwiftUI for a fast, responsive experience that works entirely offline.

CLOCK IN, CLOCK OUT, GET PAID RIGHT Track your hours with a single tap. The live clock shows your current session, daily totals, weekly progress toward 40 hours, and real-time overtime alerts. Punch breaks separately, log fatigue or per diem days, or add manual entries for past shifts.

BUILT FOR UNION WORKERS ShiftClock understands your CBA. Configure overtime and double time multipliers, choose which days of the week pay double time, set holiday pay rates, show-up time guarantees, per diem, shift differentials, and employer-paid benefits (Health & Welfare, Pension, Annuity, Apprenticeship Fund). Set it up once, then export your CBA profile and share it with your entire crew.

PER-PROJECT PAY ISOLATION Each project tracks overtime independently. If you work two jobs in the same week with different clients and different week start days, each project calculates its own OT threshold — no cross-project hour mixing that inflates or hides your real overtime.

APPRENTICE PROGRESS TRACKING Monitor your hours toward journeyperson status. Set your apprentice percentage, track cumulative hours, and see your next milestone threshold — all tied to your active project.

DETAILED REPORTS & PAY ESTIMATES Generate weekly, biweekly, or monthly pay period reports with full breakdowns: regular, overtime, and double time hours; gross pay; per diem; night differential; employer-paid benefits; and estimated federal tax withholding. Filter reports by project, view daily bar charts, and track weekly earnings goals.

PAY STUB RECONCILIATION Enter your actual paychecks to compare estimated vs. real take-home pay. Add each deduction from your stub — union dues, pension, health & welfare, taxes — and the app highlights discrepancies between your tracked gross and what you received.

PROJECT & CLIENT MANAGEMENT Create unlimited projects, link them to clients, set per-project pay rates and OT rules, configure project-specific tax settings, and add notes for contract details. Switch between active projects with one tap from the clock screen.

MILEAGE & EXPENSE TRACKING Log daily mileage with the current IRS standard rate. Track job-site expenses by category. View cumulative totals and export as CSV for tax filing.

EXPORT EVERYTHING Export reports as CSV or plain text. Back up your complete data (settings, entries, projects, clients, mileage, expenses, and pay stubs) as JSON. Import backups on a new device to pick up right where you left off. Backups are cross-platform compatible with the Android version.

WORKS OFFLINE — YOUR DATA STAYS ON YOUR DEVICE The entire app runs locally with no internet required. No accounts, no cloud sync, no subscriptions. Your time data never leaves your phone unless you export it.

TWO WORK MODES • Advanced/Union Mode: Full feature set with OT/DT multipliers, holiday pay, per diem, apprentice tracking, employer benefits, CBA profiles, and pay stub reconciliation. • Basic Mode: Simplified time tracking with clock in/out, overtime after 40 hours, and pay estimates. No DT or union-specific settings to clutter the interface. Switch between modes anytime without losing data.

SHIFTRELAY INTEGRATION Submit timecards directly to your employer through ShiftRelay. Link your employee code, and the app builds and sends your timecard automatically at the end of each pay period.
