Dawnline: Sleep Score

New: a more precise, more honest sleep score – now with sleep rhythm as its own component. No subscription, no cloud, every point explained.

Dawnline turns your sleep into one clear score from 0 to 100 – and explains every single point. Calm, understandable, no black box. Nothing that overwhelms you in the morning.

NEW IN 4.0 – A MORE PRECISE, MORE HONEST SCORE The score now measures more precisely when your night starts and ends, and for the first time factors in how regular your sleep is – the best-documented predictor of sleep health. Deep sleep and REM carry a bit less weight to make room, since no watch measures them reliably. Because the score is recalculated every time you open the app, this also changes your past history – a new explainer in the app shows exactly what changed and why.

YOUR APPLE WATCH AS ITS OWN SLEEP EXPERIENCE A complication shows your score at a glance, with no need to open the app. The trends screen can be scrubbed through the night with the Digital Crown – every turn instantly reveals heart rate, movement, and sleep stage at that moment. The entire watch interface is designed to be responsive across every display size.

YOUR READINESS A single, calm number tells you how recovered you start the day. It comes visibly from your sleep, your sleep debt and – when your Apple Watch measures them – your resting heart rate and heart rate variability. No secret; every ingredient is explained.

SLEEP VITALS Sleeping heart rate, resting heart rate, heart rate variability, respiratory rate, blood oxygen and wrist temperature – quietly shown in the night view. Just the numbers, calmly presented, straight from Apple Health.

YOUR RHYTHM How regular your sleep times are – now a real part of your score, worth 20 of 100 points, not just a display.
