About this app

Steady is the sleep and recovery companion built for people who work nights, rotations and on-call. Instead of assuming you sleep at night, it plans around your actual roster, tells you how fatigued you will be, and warns you before you get behind the wheel too tired to drive.

WHY SHIFT WORKERS USE STEADY
• Know your fatigue before it hits. A single 0–10 fatigue score from your sleep, hours awake and body clock, updated as your sleep and shifts change, with a forecast so you can fix a bad stretch before it starts.
• Get home safely. The drive-home risk alert checks your fatigue at the end of a shift and tells you when a short nap or a coffee before leaving is the smarter call.
• Wake up at the right moment. The smart wake alarm senses motion and wakes you in lighter sleep inside the window you choose, so you feel less groggy.

BUILT AROUND YOUR ROSTER
• Shift pattern templates: 4 on/4 off, Panama 2-2-3, DuPont, fixed nights, on-call, or fully custom rotations.
• See tonight, tomorrow and the days after at a glance, with a bedtime plan for each.
• Swap simulator: try a shift change and see what it does to your fatigue before you say yes.

RECOVER FASTER
• Nap planner: the best nap window and length for the shift ahead.
• Caffeine cutoff: log a cup and see whether it will still be in your system at bedtime.
• Sleep debt: how much sleep you are short and how quickly you can pay it back.
• 290 coaching tips written for rotating schedules, night shifts and irregular hours, filtered to your situation.

FITS INTO YOUR DAY
• Health Connect import: bring in sleep already tracked by your watch or ring.
• Calendar export of shifts and planned sleep; CSV export of your history.
• Wear OS companion for a glance at your score and next alarm from the wrist.
• Home-screen widget with today's fatigue score and next bedtime.
• Full English and Spanish interface.

100% OFFLINE AND PRIVATE
No account. No server. No analytics or tracking. Everything is calculated and stored on your device, and you can export or delete it whenever you like. Health Connect access is read-only and optional.

STEADY PRO
Every feature is free for 7 days. Afterwards Steady Pro is a subscription of $3.99 per month or $24.99 per year (prices shown in Google Play for your country). Subscriptions renew automatically unless cancelled in Google Play at least 24 hours before the end of the current period.

IMPORTANT
Steady is a wellness and planning tool, not a medical device. It does not diagnose, treat or prevent any condition, and its fatigue estimates are not a substitute for your own judgement, your employer's fatigue policy or medical advice. Never drive if you feel unsafe to do so, whatever the app says.
