Noctula

Noctula is the simplest way to track your baby's sleep. One tap to start, one tap to stop. No sign-ups, no internet required, no subscriptions.
SIMPLE SLEEP TRACKING
Start a sleep session with a single tap. A gentle timer tracks how long your baby sleeps. End it when they wake. That's it, no complicated menus, no learning curve.
12 SOOTHING SLEEP SOUNDS
White noise, rain, ocean waves, fan, birdsong, and more. Every sound loops seamlessly with studio-quality crossfading. Set a sleep timer to auto-stop after 15, 30, 45, or 60 minutes. Route audio to any AirPlay speaker.
LIVE ACTIVITY & WIDGETS
See your baby's sleep status right on your lock screen with Live Activity. Add home screen widgets for instant access, start and stop sessions without opening the app.
APPLE WATCH
Track sleep from your wrist. Start and stop sessions directly from your Apple Watch when your phone isn't nearby.
SLEEP HISTORY & INSIGHTS
Review every session on a beautiful heat map calendar. Track daily totals, nap counts, longest stretches, and sleep streaks. Know exactly how your baby's sleep patterns are evolving.
100% PRIVATE & OFFLINE
All data stays on your device. No accounts, no cloud sync, no analytics, no third-party code. Noctula is built entirely with native Apple frameworks, nothing leaves your phone.
PRICING
Noctula offers a 7-day free trial with full access to every feature. After the trial, unlock the app forever with a single one-time purchase of $7.99. No subscriptions, no recurring charges, no hidden fees.
