## What is LullaByte?

A little sound. A little space.

LullaByte brings offline music and gentle everyday practices together for sleep, rest and focus. Choose a sound for bedtime, a break between tasks, or a quiet reading session.

27 SOUNDS
All tracks are included with the app. Listen to free and unlocked sounds without streaming or downloading individual tracks. Browse Sleep, Rest and Focus, save favorites, and return to your listening history.

153 PRACTICE CARDS
On iPhone and iPad, explore short lessons, simple exercises and a dedicated guide for every track. Search by card, topic or music. Save a card, try an idea and notice what suits you. Your records stay on your device.

28 DAYS OF SOUND & REST
Discover a four-week program on iPhone and iPad: notice how you rest, explore your sound preferences, bring small practices into everyday life and write a rest plan of your own. Each day offers a short lesson, practical steps and an optional reflection. Most practices take about 3–8 minutes. Skip ahead, revisit a day or choose quiet instead of music. No streaks to maintain.

Lessons and exercises are free. Music follows your existing library access. You can complete every day without buying or playing music. Optional notes, weekly reflections and your rest plan save locally.

A GENTLER FINISH
Set a sleep timer, including End of Track, and choose a fade-out duration. Repeat a sound or let the session end. Quiet Mode simplifies the player after a moment; tap to bring the controls back.

10 SOUNDS, FREE FOREVER
Ten selected sounds remain free. Sleep, Rest and Focus each include at least three free sounds; tracks can appear in more than one category.

OPTIONAL LIFETIME MEMBERSHIP
A one-time in-app purchase unlocks all remaining sounds and all future sounds added through app updates. No subscription or automatic renewal. Purchase and restoration require an internet connection. After verification on this device, unlocked sounds play offline. Restore eligible purchases using the same Apple Account on your devices.

MADE FOR YOUR DEVICES
Listen on iPhone, iPad and Apple Watch. Watch includes playback controls, favorites and a sleep timer. Practice cards and the 28-day program are available on iPhone and iPad. Local progress does not sync between devices.

YOUR LANGUAGE, YOUR PACE
Choose English (US), Simplified Chinese, Traditional Chinese or Japanese, or follow your system language. Switch between light, dark and system appearance.

NO ACCOUNT REQUIRED
No advertising or tracking. Favorites, listening history, settings and practice notes stay on your device.
