The idea

You’ve tried the magnesium, the mouth tape, the 9 p.m. phone jail. Nocturne starts somewhere else: with your actual nights. It notices the flat white you had at 15:20, the run you squeezed in after work, the meeting that ran late, and quietly rewrites tonight. A wind-down that fits your evening. Sound that listens back. An alarm that waits for you to be ready.

Tonight’s forecast

Every evening, a plan written for this exact night.

At 18:00 Nocturne looks at how you slept, how today went and what’s on tomorrow, then drafts tonight. It’s there the moment you open the app. It’s usually right. When it isn’t, it learns.

How it works

One night, in three acts.

01 Wind down

03 Wake gently

Act I

Wind down

21:30 – 23:00

Dim the day, in stages.

Nocturne reads your afternoon, the 15:20 flat white and the late call included, and times a wind-down that starts where you actually are. Lamps warm, screens go amber, then four minutes of breathing. Nothing to remember. The reminders arrive when they’re needed.

Act II

Drift

23:00 – 06:20

Sound that listens back.

Rain far away, a low brown hum, a night train you’ll never catch. The mix follows your breathing, thins out as it slows, and goes silent in deep sleep. Stir at 03:12 and it returns, quietly, before you’ve noticed you were awake.

Act III

Wake gently

06:20 – 06:45

An alarm that waits for light sleep.

Set a window, not a time. Nocturne watches for your lightest moment inside it, raises a sunrise on your screen and lets birdsong in at a whisper. Worst case, it rings at your hard stop. Never late. Just less startled.

The science

We measured it, because you’d ask.

Eight weeks, 1,284 people, 91,406 nights. Each person was compared with their own first two weeks, the most honest control group we could find.

Falling asleep

18

minutes faster

Median time to fall asleep went from 32 minutes to 14 by week eight.

“The biggest gains didn’t come from earlier bedtimes. They came from moving the last coffee and the last bright screen.”

Method. Nocturne Sleep Study, February–April 2026, run by our in-house research team. Adults used Nocturne+ for eight weeks with a phone or wearable, plus a two-question morning diary. Results compare each participant with their own two-week baseline; the study was not randomised or blinded, and figures are medians unless noted. Nocturne is a wellness app, not a medical device.

FAQ

Questions people ask at 2 a.m.

Still awake? Write to hello@nocturne.sleep. A human replies by breakfast.

Do I need a smartwatch or a ring?

No. Put your phone on the mattress and Nocturne uses motion, and sound if you allow it, to estimate your stages. A watch or ring sharpens the picture and syncs in a minute, but you can start tonight without one.
