Sleeper
Read full descriptionHide full description
Sleeper is not another generic relaxation app. It's a sound-masking system built to solve one very specific problem: you can't sleep because of a noise you don't control. We don't sell "nice sounds." Every mask inside Sleeper is engineered to cancel one exact type of noise — footsteps and slamming doors upstairs, a TV or voices through the wall, a partner's snoring, traffic outside your window, a hotel corridor, a dog barking, a baby crying. You pick the noise that's keeping you up, and Sleeper gives you the exact counter-frequency for it. How it works: your brain never fully stops listening while you sleep. What actually wakes you up is the sudden jump between silence and a noise spike — a door, a voice, an engine. Sleeper raises your room's background level in a steady, controlled way (using precisely tuned white, pink and brown noise layered with real-world sounds like rain or airplane cabin) so that jump disappears. No contrast, no alarm signal to your brain, no waking up. Built around real situations, not generic scenes: • Noisy Neighbors — separate masks for footsteps, voices/TV, and impacts through walls and ceilings • Traffic & Street — continuous coverage for sirens, motorcycles and the rise-and-fall of traffic • Snoring Partner — a low-frequency mask you can play from your phone without leaving the bed • Hotel & Hospital — masks for corridor noise, door slams, and nearby equipment beeps • Airport & Flight — engine drone and boarding-area coverage for the road warrior • Construction & Renovation — masks tuned specifically for hammering and drilling • Barking Dogs & Crying Babies — layered coverage for sudden, high-pitched sound spikes • Rain Sounds — seven natural rain-based masks, from soft rain to full storm Each mask lets you control volume independently, so you build a different mix for a different night. Add a sleep timer with a fade-out so gentle you won't notice it end, and background playback that keeps protecting your sleep all night, screen locked, calls and alarms handled automatically. Sleeper won't stop your neighbor, the traffic, or your partner's snoring. It stops your body from reacting to it — so you fall asleep without fighting the room, stay asleep without being pulled back by every sound, and wake up actually rested. Available in English, Portuguese, Spanish, Arabic, Chinese and Hindi.
