## What is Shizumori?

Shizumori is a calm, dark, beautifully simple sound app for sleep, focus, relaxation, soothing a baby, and masking tinnitus.

Mix over 100 high-quality soundscapes across 15 categories — rain, ocean, fire, wind, water, white/brown/pink noise, fans, clocks, nature and more — into your own perfect blend. Save your mixes, set a sleep timer, and drift off.

WHY SHIZUMORI
• 100+ sounds, 15 categories — layer any of them into custom mixes
• Never stops — your sound keeps playing during calls, videos and games
• Tinnitus tone & filter — find your personal frequency and shape a notch filter that sits alongside your ringing instead of clashing with it
• Calming breathing exercises paired with sound
• One-tap ready mixes for sleep, focus, babies and calm
• Sleep timer with a gentle fade-out
• Beautiful, dark, distraction-free design

FOR EVERY MOMENT
• Sleep — soften the room and fall asleep faster
• Babies — gentle white noise and womb-like textures to settle little ones
• Focus — steady background sound to block out distractions
• Tinnitus — broadband masking sounds that help the ringing fade into the background
• Calm — unwind anytime, anywhere

Shizumori is a relaxation and sound-masking tool. It does not diagnose, treat, or cure any condition.

Start free. Build your first mix in seconds.
