Steady is built for shift workers, not 9-to-5. NEW IN 1.8 • A 3-minute reaction test before you drive home, compared with your own rested speed. A fatigue check, not a driving test. • Switching to nights or back to days: Steady plans the days around it, with bedtimes, light and a nap before the first night. • Your next 24 hours on one line: work, sleep, naps and your caffeine cutoff. • iPhone Duo: stand it half open and Steady becomes a nightstand. WHAT MAKES STEADY DIFFERENT • Drive home risk alert: warns you when fatigue makes the drive too risky. 17 hours awake is roughly a 0.05% BAC. Always free. • Roster import from a photo: point your camera at the schedule on the wall and confirm every day before it's saved. • An alertness curve that shows when you'll crash, plus the best windows for exercise, meals and light. • A sleep score measured against your own rotation, not a 9-to-5 clock. • Sleep debt and a payback plan built around your real rota. • Smart wake alarm: wakes you in light sleep within a window you choose, backed by a real system alarm on iOS 26 and later. • 290 coaching tips grounded in AASM, NIOSH and chronobiology research. • English and Spanish, written natively in both. • Private and on-device: no accounts, no servers, no tracking.
