— 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.
