Nocturn
Healthier sleep and circadian habits for people whose schedules do not fit a nine-to-five.
Version 1.0.0 · Android · Direct APK download
Built around your day, not the calendar's.
Four things, done quietly: a day that starts when you say it does, a roster that matches your rotation, a short habit checklist and the numbers that show you are keeping it up.
A rolling 24-hour day window
Your day starts when you say it does. Nocturn runs on a custom rolling 24-hour window, and the dashboard always shows which day you are in right now.
A shift roster with rotation presets
Lay out your roster on the same rolling day. Seven common rotations are built in, so a standard roster is a tap away rather than a spreadsheet.
A daily habit checklist
A short list of habits sits beside the day window, so each one belongs to your day and not to a calendar date. Tick them off as you go.
Streaks and completion stats
Today's streak, your best streak and total checks — completion momentum at a glance, without harsh bright colours.
For people who work while others sleep.
Nocturn is sleep and habits for night-shift workers — and for anyone on a rotating schedule that does not fit a nine-to-five. It gives that schedule its own day, its own roster and its own small list of habits, in an interface that stays easy on the eyes at night.
It is built by S. S. Dhillon and is still in development. There is no Play Store listing yet; the current build is shared directly from this site.

Two books, one method.
While Nocturn is in development, the books cover the AI side — a complete operating method for a business, and a handbook of prompts for everyday work. Both are digital editions.
