ShiftMaster Pro: Shift & Overtime Pay Logger

Shift workers, nurses, factory operators, and retail staff lose hundreds of dollars every year due to untracked overtime hours, night differentials, and payroll calculation errors. Mainstream shift apps charge $30–$60/year subscriptions, require employer accounts, and upload private schedule data to the cloud. ShiftMaster Pro logs shifts in 1 tap, automatically computes 1.5x and 2.0x overtime thresholds, incorporates unpaid lunch breaks and hazard differentials, and forecasts net take-home pay 100% offline.
