Dawnline: Sleep Score

New: Readiness — a calm, explainable recovery score for your day. Plus sleep vitals and your sleep rhythm. No subscription, no cloud, all on your device.

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 2.0 — 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 — a quiet but meaningful measure.

WHY DAWNLINE • No subscription — $0.99 once, every feature forever • No cloud — your data never leaves your device • Transparent score — every component visibly explained

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 7 nights • Morning glance on Apple Watch • 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.
