Shift Fuel is the meal-timing app built for rotating shift workers — nurses, CNAs, hospital crews, and anyone on nights or a 2-2-3. No macro tracking. No calorie math. Clear windows: fuel before your shift, eat mid-shift, wind down after nights. WHAT YOU GET (FREE) • Meal windows aligned to YOUR shift start, sleep, and rotation • Today view with countdowns and what’s next • Rotations: 2-2-3, 4-on-4-off, Panama, or a custom week • Night-shift aware caffeine and wind-down guidance • On-device privacy — schedule stays on your iPhone / iCloud SHIFT FUEL PRO • Full week meal planner across your rotation • Local reminders before eating windows • Home Screen widget & Live Activity • Monthly, yearly, or pay-once lifetime Made for people who eat dinner at 6 PM before a 7-to-7 — because generic diet apps don’t get shift life. Not medical advice.
