Slumby: White Noise & Sleep

Sleep sounds, white noise and focus ambience in one app. Slumby is an ambient sound mixer that lets you build your own background sound, for deep sleep at night and for focus work during the day. 🌙 Most sleep apps hand you fixed tracks. If the track does not suit your room, that is the end of it. Slumby plays several sounds at once and gives each one its own volume. Heavy rain over brown noise with a little fireplace crackle. Build the mix once, then use it every night. 🎧 WHY SLUMBY A steady, unchanging sound covers the neighbor upstairs, traffic outside and snoring next to you. It also gives a busy mind something flat to settle against. That is what makes it work as a sleep aid, as tinnitus masking, and as study sounds for a session where every noise pulls you out. It is a white noise machine that fits in your pocket. ✨ FEATURES 🔊 CUSTOM AMBIENT SOUND MIXER Layer multiple tracks and set the volume of each one. More rain, less brown noise, until the balance is right for you. 🌧️ FULL SOUND LIBRARY High quality audio, all included: • Rain sounds, heavy rain and thunderstorms • White noise, brown noise and pink noise • Fan noise for a constant, flat hum • Crackling fireplace • Ocean waves and flowing streams • Forest and nature sounds ⏳ SLEEP TIMER WITH FADE OUT Set the timer and the volume fades down before playback stops. No sudden silence at 3am, and nothing running until morning on your battery. Let the sleep sounds run all night for deep sleep, or fade out after twenty minutes for a nap. 🧠 FOCUS, STUDY AND DEEP WORK Slumby is not only for bedtime. Use it as a focus timer companion: start a pomodoro block, put on a study sounds mix, and let the fade out mark the end of the session. Cover office chatter in an open plan room, hold concentration through long reading, or keep a quiet room from going silent while you work. Students use brown noise and rain sounds for exam revision. Remote workers use fan noise and ambient sounds all day. 📴 OFFLINE MODE AND BACKGROUND PLAY Every sound ships inside the app. Play in airplane mode, on the train, or anywhere with no signal, and use no data doing it. Audio keeps running with the screen locked or while you use another app. 🌟 WHO SLUMBY IS FOR • Anyone with insomnia or light sleep who wakes at any noise • People on a busy street, near construction, or under noisy neighbors • Students and professionals who need hours of concentration • Tinnitus sufferers who use masking sounds • Parents settling a baby with white noise • Anyone who wants a nap sound that shuts itself off Open Slumby, build your mix, and turn your phone into a sound machine you actually control. 💤
