Most shift apps are team tools for managers scheduling a crew. ShiftGrid is the personal version - one worker, one rota, on their own phone. A rotating pattern is a formula, so it should not be typed in by hand. Pick a preset - 2 on / 2 off, 4 on / 4 off, 2-2-3 Pitman - or build any cycle length, set a start date, and years of schedule generate instantly. Override any day for swaps, sick leave or vacation without breaking the pattern Fully offline. No account, no cloud, no ads, no subscription
