Instead of a fixed playlist, Attune layers real-time binaural tones, curated solfeggio frequencies, high-quality ambient beds, and natural soundscapes — so you can build the exact texture that helps you settle in. DESIGN YOUR SOUND • Layer mixer — blend binaural tone, ambient bed, and noise with per-layer volume • Curated frequency chips — pick a tone (174–852 Hz) and a brainwave band (Delta to Gamma) in one tap • High-quality beds — ocean, rain, and aurora ambiences, gaplessly looped • Procedural noise — white, pink, and brown ONE-TAP PRESETS • Deep Focus · Flow State · Clear Mind — for work and study • Ocean Calm · Soft Rain Focus — for unwinding • Delta Sleep · Aurora Drift — for winding down CLASSICAL MUSIC • A curated library of rights-clean classical recordings — Bach, Beethoven, Chopin, Debussy, Satie, Schubert, and more • Browse by composer; multi-movement works play gaplessly • Every recording is public-domain or openly licensed and credited in the app — a free sampler is included, with the full library in Attune Pro BUILT FOR EVERYDAY USE • Session timer with a gentle fade-out, or keep playing • Background playback and full lock-screen controls • Dynamic Island & Live Activity — control it without opening the app • Universal Purchase — one download for iPhone and Mac • On your Mac, Attune lives quietly in the menu bar CALM BY DESIGN A "Minimal Zen" interface — near-monochrome, wide open space, a single sage accent — so you can adjust with your eyes half-closed and get back to what you were doing. PRIVATE BY DEFAULT No account. No ads. No tracking. Every sound is generated and mixed on your device, so it works fully offline. Attune is a sound tool for focus and relaxation.
