1. Built to Replace Paywalled Legacy Time Trackers
The Work Hours Calculator mobile application (Package ID: com.workhourscalculator.app) brings our full US payroll, state overtime, and wage-protection suite directly to your Android phone, iPhone, tablet, or desktop—working 100% offline via Service Worker caching and local storage.
- Timestamp-Anchored Live Punch Clock: Unlike legacy Android apps whose timers die when the OS battery saver puts the app to sleep, our punch clock records exact Unix timestamps (
clockInTs), ensuring 100% accuracy even if you reboot your phone mid-shift. - 5 Adaptive Background Themes: Switch seamlessly between Midnight Slate, Pure OLED Carbon & Gold (saves battery on AMOLED screens), Deep Forest Emerald, Royal Sapphire Navy, and Crisp Apple Daylight.
- Zero Subscription Paywalls: Unlimited CSV exports, printable PDF timecards with signature blocks, and 1-click JSON backups are free forever.
