Beautiful sleep insights, every night.

HappensNightly turns your Apple Health sleep data into a calm, color-coded chart you'll actually want to look at. See patterns. Log nights. Build better habits.

  • ● HealthKit-powered
  • ● 100% private
  • ● No subscription

Everything to understand a night.

Visualize, log, and learn from your sleep — without ads, accounts, or a single hidden subscription.

The Sleep Chart

14-night vertical timelines, color-coded by duration. Spot bedtime drift and recovery streaks at a glance.

HealthKit Native

Reads your sleep records directly from Apple Health. Nothing is written back. No third-party syncing.

Daily Journal

Log sleep quality, workouts, caffeine, and screen time before bed. Watch which habits actually matter.

Bedtime Targets

Set a goal bedtime and wake. Dashed reference lines show which nights you hit your target.

Caffeine Tracking

Tap the hour you had your coffee. See the correlation with last night's sleep instantly.

Screen Time Logging

Log how long you stared at a screen before bed — None to 2h+ in one tap.

Sleep Quality Ratings

Five levels from Restless to Excellent — capture how you actually felt, not just how long you slept.

Bedtime Reminders

Get a calm notification 10, 30, or 60 minutes before your target — the easiest way to wind down on time.

Consistency Streaks

Track how many nights in a row you hit your target bedtime and wake time — with a gentle streak counter, weekly, and monthly hit rate.

Export & Import

Export your journal as JSON anytime. Move to a new iPhone? Import in seconds.

Designed for late nights.

Deep navy backgrounds, soft glow, and zero noise — built to be checked before bed and right after waking up.

Your sleep stays on your phone.

HappensNightly was built for people who don't want their health data mined, sold, or backed up to someone else's server. There's no cloud, no account, no analytics. Just your data, beautifully presented.

  • No accounts. No sign-up.
  • Reads Apple Health — never writes to it.
  • Journal stays on-device. Export anytime as JSON.
  • No ads, no tracking, no third-party SDKs.
  • One-time purchase. No subscription.

HealthKit, the right way.

HappensNightly requests read-only access. The Apple permission sheet shows exactly what data we'll see — and you can revoke it anytime in Settings → Health.
