Steady vs ShiftRhythm

Steady is built for shift workers, not 9-to-5. WHAT MAKES STEADY DIFFERENT Drive home risk alert When fatigue makes driving home too risky, Steady warns you before you get in the car. Drowsy driving is comparable to drunk driving, 17 hours awake is roughly a 0.05% BAC, 24 hours awake is roughly 0.10%. No other shift-work app ships this warning the way Steady does. Smart wake alarm Wakes you in your lightest sleep within a 30-minute window. Beats your iPhone's default alarm for anyone who can't sleep on a 9-to-5 clock. 3-day fatigue forecast See your hardest days before they hit, then plan around them. 300+ evidence-based coaching tips Grounded in research from the American Academy of Sleep Medicine, NIOSH, and Czeisler and Walker's chronobiology work. Routed to your current state, not rotated randomly. Bilingual English and Spanish Written natively in both languages. Not a translation, full native UX in either language. Private, on-device No accounts, no servers, no tracking. Your sleep data never leaves your phone. Carries Apple's "Data Not Collected" privacy badge.

STEADY PRO Free 7-day trial. $3.99 per month or $24.99 per year, still a fraction of what comparable shift and sleep apps charge.

WHY WE BUILT THIS Most shift workers don't get to choose their schedules. They do get to choose how they recover. Steady is the app that helps you do that, without selling your data or charging $70 a year. Steady is not a medical device. Always consult a licensed clinician for medical advice.
