## What is Serenity?

Fall asleep faster. Stay focused longer. Serenity generates beautiful ambient soundscapes — no loops, no downloads, no internet required.

WHY SERENITY?

50 Algorithmically Generated Sounds
Unlike apps that play short audio loops, Serenity creates infinite, non-repeating soundscapes using advanced audio synthesis. Rain that never repeats. Waves that never loop. True sonic immersion.

5 Categories: Nature, Noise, Water, Weather & Ambient
From birdsong and whale calls to brown noise and rain on a tin roof. 15 sounds are free, with 35 more available as individual tips ($0.99 each) or unlock everything with Serenity Pro ($5.99).

Mix & Match
Layer multiple sounds together — rain on a cafe window, crackling fire with crickets, ocean waves with gentle wind. Save your favorite combinations and switch between them instantly.

4-7-8 Breathing Exercise
The scientifically-backed breathing technique that helps you fall asleep in minutes. Beautiful animated guide with haptic feedback.

Smart Timer
Sleep timer with gentle fade-out so sounds don't end abruptly. Set it and drift off.

100% Private
Zero data collection. Zero tracking. Zero ads. No internet required. Everything happens on your device. Period.

Fully Accessible
Complete VoiceOver support, Dynamic Type, and high contrast throughout. Designed for everyone.

22 Languages
Localized for a global audience.

Designed with Apple's Liquid Glass interface for iOS 26.
