Hush — Focus Sounds

Hush is a focus sounds app that lets you build layered soundscapes from real-time noise generators, brainwave entrainment, and 80+ ambient sound samples. MIX UP TO 6 SOUNDS AT ONCE Combine noise generators, binaural beats, and ambient recordings into a single layered mix. Each source has its own volume control so you can dial in exactly the right balance. NOISE GENERATORS White, pink, brown, and gray noise synthesized in real time — not loops, so every second sounds natural. BRAINWAVE ENTRAINMENT Binaural beats (Alpha, SMR, Beta, Gamma), isochronic tones, and monaural beats to support focus, relaxation, and deep work. Adjustable carrier frequency. 80+ AMBIENT SOUNDS Rain on a tent, cat purring, coffee shop chatter, vinyl crackle, crackling fire, underwater, train rides, and dozens more — organized across 12 categories. BUILT-IN & CUSTOM PRESETS Start with curated presets like Deep Work, Coffee Shop, Storm, or Cozy — or save your own. A Random Mix button generates fresh combinations when you want something new. FOCUS TIMER Set a countdown from 1 to 180 minutes. Sounds fade out gently in the final seconds, with an optional chime when time is up. WORKS IN THE BACKGROUND Control playback from your Lock Screen and Control Center. Your last session is automatically restored when you reopen the app. PRIVATE BY DESIGN No account required. No ads. No tracking. No data collection.
