HappensNightly

Track your sleep patterns at a glance. Beautiful 14-night charts, daily journal, and HealthKit-powered insights to help you build better sleep habits.

See your sleep like never before.

HappensNightly turns your Apple Health sleep data into a beautiful, color-coded chart that reveals patterns you've never noticed. No more scrolling through endless tables — just a clean visual story of how you actually sleep.

THE SLEEP CHART A vertical timeline of your nights, color-coded by total sleep duration: • Green for ≥6 hours • Orange for 4–5 hours • Red for under 4 hours

Tap any night to see a detailed breakdown — bedtime, wake time, total duration, and your overnight resting heart rate, HRV, and SpO₂. Switch between 2-week, 1-month, and 3-month views to spot trends.

DAILY JOURNAL Log what shaped your night: • Sleep quality (Restless → Excellent) • Workouts with type and time • Caffeine intake throughout the day • Screen time before bed • Morning notes

Then watch which habits actually affect your sleep when you tap a night on the chart.

PERSONAL TARGETS Set your ideal bedtime and wake time. HappensNightly draws dashed reference lines right on the chart so you can see at a glance which nights you hit your goal and which you missed.

BEDTIME REMINDERS Get a gentle notification 10, 30, or 60 minutes before your target bedtime — the easiest way to actually wind down on schedule.

PRIVATE BY DESIGN • All your data stays on your device • HappensNightly reads sleep data from Apple Health but never writes to it • No accounts, no cloud sync, no ads, no tracking • Export your journal anytime as a JSON backup

REQUIREMENTS Sleep data must already be tracked in Apple Health (via Apple Watch, third-party sleep apps, or manual entry). HappensNightly visualizes what's there — it doesn't track sleep on its own.

Designed for people who want a calm, focused way to understand their sleep without subscriptions, gimmicks, or social features. Just your data, beautifully presented.
