iPhone
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.
