Concentration Maker
Hyeonsu Seo
Your own quiet little room — 80 cozy sounds to sleep, study and breathe to. Quiet Room used to be a tiny white-noise app. Version 2 is a full rebuild: five times the sounds, a study timer, a breathing bubble and the cutest pastel rooms — still completely offline, still zero ads. 80 SOUNDS, ALL YOURS White, pink, brown (and cotton-candy!) noise, eight kinds of rain, calm waves and pebble beaches, crickets and frogs and one sleepy owl, crackling fireplaces, ticking clocks, night trains, cafe murmur, a cat purring on your lap, music boxes, singing bowls, lo-fi grooves, even deep space. Every sound loops seamlessly and plays with the screen off. MIX YOUR MOOD Layer any sounds, set each volume, and save the blend with a cute name and emoji. Or start from ready-made mixes like Rainy Library, Cat-nap Lap, Winter Den and Space Walk. SLEEP TIMER 15 to 90 minutes, with a gentle 20-second fade so it never jolts you awake. STUDY BUDDY A pomodoro-style focus timer with a soft chime between rounds — collect a strawberry for every round you finish. Works with the screen off. BREATHING BUBBLE 4-4-6 guided breathing for racing minds. Three rounds and your heart slows right down. MAKE IT YOURS Five pastel theme packs — Strawberry Milk, Lavender Dream, Mint Choco, Peach Fuzz and Midnight — each with light and dark looks, plus a sleepy cloud who naps while your sounds play. PRIVATE BY DESIGN Pay once, own it forever. No account, no ads, no subscriptions, no analytics, no network access. Your mixes never leave your phone. Made by GDLabs — small, honest tools that respect your attention.
