Store description excerpt
Lull turns your phone into a calm, private soundscape for focus, relaxation and sleep — and it works completely offline. Tap any sound to start, layer several together, and fine-tune the volume of each one to build your perfect mix. Rain on a campfire night, ocean waves with a soft breeze, or pure brown noise for deep work — it's up to you. KEY FEATURES • 12 ambient sounds you can mix freely — rain, heavy rain, ocean, stream, wind, campfire, night, cafe, fan, and white / pink / brown noise • Independent volume slider for every active sound • One-tap mixes like "Rainy cafe", "Deep focus" and "Sleep" • Sleep timer that gently fades the sound out so you can drift off • Pomodoro mode — sounds play while you focus and pause on breaks • Keep-screen-on option for nightstand use • 100% offline — no streaming, no account, no data leaves your device • Light / dark themes and English / Japanese Just calm sound whenever you need it.
