Focusnest - Mix noise and nature sounds to enter your focus mode

Hey Product Hunt! I'm the maker of Focusnest — a free iOS app that helps you create the perfect sound environment for deep work, relaxation, or sleep. Why I built this: As an engineer, I rely on ambient sound to get into the zone. But most apps felt too cluttered, required subscriptions, or needed an internet connection. I wanted something dead simple — pick your sounds, adjust the mix, hit play, and focus. What makes Focusnest different: - Sound mixing — Blend white, brown, and pink noise with nature sounds (rain, streams, campfire, waves, birds, wind, thunder) with individual volume control - One-tap presets — Save your favorite soundscapes and switch instantly - Pomodoro timer — Built-in focus/break cycles so you stay on track - 1/f fluctuation — Natural sound variation that makes the audio feel alive, not robotic - Fully offline — No internet needed, works anywhere - Background playback — Keep the sound running while you use other apps It's completely free with no ads and no paywalls. Whether you code, study, write, or just need to wind down — I'd love to hear how you use it!
