Dygn
The right nudge, on time
A full 24-hour day, held as a dial. Dygn nudges you at the right time for light, caffeine, meals, movement, wind-down and sleep — then lets you mark Done, Snooze, or Skip.
How it works
See the day. Follow now. Tap what happened.
Complex clocks, a simple loop. Your rhythm is an arc; the bright needle is now.
02
The Now card
One card for the current nudge. Not a feed. Not a score. Just what this hour is for.
03
Done, Snooze, Skip
Reminders you can actually answer. No streak theatre — a record that you followed through, later, or not this time.
Protocol
The right action, at the right clock.
Light
Seek it when the dial says so. UV and cloud cover shape how long outdoors is enough.
Caffeine
A window, not a lecture. Know when caffeine is still on the table — and when to close it.
Meals
Timed with the rest of the day, so dinner does not collide with wind-down.
Movement
Train times Zone 2 and harder work to your rhythm, including short sessions on travel days.
Wind-down
Dim the day on purpose. The Now card tells you when to start.
Sleep
A target window on the arc from wake to bed — then a tap that you kept it.
Train
Workouts timed to your rhythm.
Hard work wants a window. Train places Zone 2 and heavier sessions on the same clock as light and sleep — and shortens the plan when you are on a travel day, in a hotel room or a gym.
Log a session, plan the next one, or read history and load without leaving the tab.
Sky
Weather that shapes the light advice. Moon, on device.
UV, cloud cover, sunrise and sunset are not decoration. They change how long outdoors is the default. Moon phase, illumination, rise and set are computed on the iPhone — no network required for the sky clock.
Trip
Jet lag, planned before, during, and after.
Add a flight. Dygn builds light, sleep, nap, and caffeine plans for the days around it. Optional melatonin windows are times, never a dose — skip them if you do not already use melatonin.
Dygn is not a medical device and does not diagnose, treat, or cure any condition.
Sources
Apple Health, WHOOP, Oura — optional, on this phone.
Connect what you already wear. Sleep, HRV, resting heart rate, daylight, and workouts can inform the daily protocol. Widgets keep the dial and the next nudge on the Home Screen. You do not need WHOOP or Oura; Apple Health is enough, and Demo mode needs no accounts at all.
Apple Health
Read sleep, HRV, heart rate, daylight, and workouts. Write workouts you log in Dygn.
WHOOP
Optional recovery, sleep, and workout summaries fetched to this iPhone.
Oura
Optional, same idea. Tokens live in the Keychain. Disconnecting removes them.
Widgets
Glance the dial and the current nudge without opening the app.
Privacy
No data collected. Nothing to sell.
There is no Dygn server and no custom backend. Schedule, completions, and trip details live on the iPhone and, if iCloud is on, in that Apple ID’s private CloudKit database. Nobody else, including the developer, can read your Dygn data. No account, no tracking, no ads.
