ShiftSlayer brings your schedule, worked hours, overtime, PTO, and paycheck estimates together in one clear workspace built for shift workers. Plan repeating or custom rotations, browse your schedule on a monthly calendar, and record what you actually worked. ShiftSlayer keeps scheduled time separate from completed work so earned-so-far totals stay meaningful while projections still help you plan ahead. See regular and overtime hours, unpaid breaks, shift differentials, on-call pay, call-in premiums, bonuses, deductions, and estimated taxes in one paycheck view. Choose weekly, biweekly, semi-monthly, or monthly pay periods and configure the overtime rules that match your workplace. Review prior pay periods, enter the actual values from a paystub, and compare them with the estimate. Track PTO balances and requests alongside the schedule that uses them. Your core data stays on your device. Automatic local restore points help protect against accidental changes. An optional ShiftSlayer account can store an encrypted cloud backup for recovery. The backup is encrypted on your device before upload. ShiftSlayer includes no advertising or cross-app tracking. Notifications are optional and scheduled on your device. Paycheck and tax results are estimates for planning and informational purposes. Your employer’s official time and payroll records remain the final record. Optional ShiftSlayer Pro Monthly ($3.99/month in the U.S.) or Annual ($29.99/year in the U.S.) unlock the same advanced paycheck audits, earnings and overtime trends, and custom reports. Prices are shown in your local currency where available. Existing free features, iCloud backup and recovery, and custom entry pay rates remain free. No free trial. Payment is charged to your Apple Account on confirmation. Subscriptions renew automatically unless cancelled at least 24 hours before the current period ends. Manage or cancel in Apple subscription settings.

Verdict
The clearest difference is in-app purchases: Shift & Overtime Tracker at none against ShiftSlayer's 2. ShiftSlayer's advantage is ads (none vs shown) and update cadence (daily vs every 5 days). On price, device support and iOS requirement there is nothing between them.
