## What is Dawnline?

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.

WHY DAWNLINE
• No subscription – $4.99 once, every feature forever
• No cloud – your data never leaves your device
• Transparent score – every component visibly explained
• An Apple Watch experience that becomes the real star, not an afterthought

YOUR NIGHT AT A GLANCE
• Dawn Ring: your score, filling like a sunrise
• Moonline: your hypnogram as a calm wave instead of hard bars
• Sleep debt across your last 14 nights
• Watch complication: your score at a glance, no app needed
• Digital Crown trends: scrub through your night, raw values included
• Smart Alarm on the Watch: wakes you during light sleep within your wake window – with a guaranteed alarm at the window's end

SLEEP LAB – SNORE ANALYSIS, FULLY PRIVATE
Detect snoring episodes right on your iPhone. Audio is analyzed live and never recorded, stored, or transmitted – only summaries are kept (duration, episodes, timeline).

ALWAYS IN VIEW
• Home Screen and Lock Screen widgets with score and sleep debt
• Siri & Shortcuts: "How was my sleep?"

PRIVACY BY ARCHITECTURE
Dawnline has no server, no account, and no networking code. Apple Health is the only data source – read-only. This applies equally to iPhone and Watch.

Dawnline is not a medical device and does not replace professional medical advice.

## Version history (last 4 releases)

### 4.0 — 2026-08-10

Dawnline 4.0 recalculates your sleep score.

Two things changed. First, Dawnline now measures your night more precisely: bedtime and time in bed now come from your Apple Watch's sleep stages instead of an iPhone signal Apple itself no longer maintains. Second, the score now factors in how regular your sleep is – the best-documented predictor of sleep health, one the score never counted before. To make room, deep sleep and REM carry a bit less weight, since no watch measures them reliably.

Because the score is freshly calculated from Apple Health every time you open the app, this also changes your past history. That's intentional, not a bug – a new explainer shows what changed and why.

Also: your sleep balance now looks back 14 days instead of 7, and naps count in full.

Everything else stays the same: no subscription, no cloud, every point explained.

### 2.0 — 2026-07-23

Dawnline 2.0 brings three calm new perspectives on your sleep:

• Readiness — an explainable recovery score for the day, drawn from your sleep, your sleep debt and (if your Watch measures them) resting heart rate & HRV.
• Vitals — sleeping heart rate, respiratory rate, blood oxygen and more, quietly shown in the night view.
• Rhythm — how regular your sleep times are.

Everything stays on your device. No subscription, no cloud.

### 1.0.1 — 2026-07-20
