## What is Lull?

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.
