## What is Sereno?

Sereno turns your phone into a high-end sound machine for sleep, focus, and calm. Dozens of hand-tuned sounds are generated live on your device and blend into 1000+ unique soundscapes — so the rain never loops and the ocean never repeats, just an endless, gentle mix that carries you through the night.

Pay once. No subscription. No ads. No account. Works fully offline.

— DOZENS OF SOUNDS, 1000+ BLENDS —
Real-time synthesis means sound that never repeats. Start with dozens of living sounds — colored noise (white, pink, brown), rain, ocean, wind, streams, fire, night crickets, fans, and more — then layer and tune them into over 1000 unique soundscapes. Every play is a fresh performance.

— UNLIMITED MIXING —
Layer as many sounds as you like. Set the volume, balance, and EQ of every track to build your perfect mix — thunder over a crackling fire, rain on a tent, a fan behind soft brown noise.

— EVERY SCENARIO —
Ready-made scenes for sleep, deep focus, ADHD focus, study, relaxation, meditation, tinnitus relief, baby sleep, travel, and more. Save and name your own.

— GENTLE SLEEP TOOLS —
A sleep timer that fades out softly instead of cutting off, plus a sunrise wake that swells in birdsong to greet the morning.

— FOCUS & ADHD —
Steady brown and pink noise can quiet a busy mind and help you stay on task. Purpose-built focus scenes for work, study, and ADHD.

— MADE TO FEEL CALM —
A serene, dark-first design with slow, breathing motion and calming themes. Background playback, lock-screen and AirPlay controls, and an immersive bedside mode that dims to the sound.

— PRIVATE BY DESIGN —
No tracking, no ads, no account, no data collected. Everything stays on your device.

Unlock Sereno Pro once for every sound, unlimited layers, all scenes, tuning controls, and more — yours forever.
