Read any list of sleep hygiene tips and you can hear the hidden assumption underneath: go to bed at the same time every night, get morning sunlight, wind down in the evening. It is decent guidance for people whose work happens in daylight. Now hand it to a nurse rotating between day and night shifts, or a factory crew on a 2-2-3 pattern, and it reads like advice from another planet. Same time every night? Which night? The one that starts at 7 a.m.?
The people the advice forgot
Tens of millions of people work evenings, nights, or rotations. They are disproportionately the people we call essential: hospital staff, EMS, warehouse and plant workers, transit operators. And nearly all mainstream sleep tooling treats their schedule as an error state. Apps assume one sleep block per day, anchored to midnight. Charts break when you sleep twice in 24 hours. Streaks shatter the first week a rotation flips. The message, intended or not, is that their sleep is wrong, when really the software is.
What I changed after listening
Steady, the studio's sleep and fatigue app for shift workers, came out of exactly those conversations, and two design decisions matter more than any feature list. First, the schedule is the source of truth, not the clock. The app thinks in shifts and sleep windows, so a noon bedtime is just a bedtime, never an anomaly to be corrected. Second, there are no streaks and no guilt mechanics anywhere. A rotating schedule guarantees broken patterns, and software that punishes a nurse for her employer's roster is not a wellness tool, it is a nag with a chart.
What the app offers instead is a plain fatigue picture: how much sleep you have actually banked against your upcoming shifts, when your low-alertness windows are likely to fall, and a gentle plan for the next sleep opportunity. Information, not judgment.
The honest boundaries
Two things I want to say plainly, because health software should be humble. Steady is not a medical device and does not diagnose anything. Persistent, severe sleep problems deserve a clinician, not an app, and shift work disorder is a real condition a doctor can actually help with. And no app deletes the underlying truth that rotating shifts are biologically hard. Software can help you spend your limited sleep opportunities a little better. It cannot make 3 a.m. a humane time to be awake, and pretending otherwise would be selling, not helping.
What shift workers taught me, in the end, was not really about sleep. It was that "default" settings, in software and in advice, quietly describe a default person, and millions of people live outside that default. Building for them starts with believing their schedule is legitimate. Everything else follows from that.
