ClearBell Sound Lab

🔔 Sleep well with ClearBell.
ClearBell Sound Lab is your personal calm — a beautifully crafted app that turns ambient sounds, music, voice, and creative audio tools into soundscapes made just for you. Whether you're winding down for sleep, settling in for deep work, or simply taking a quiet moment, ClearBell is here to help you breathe out.
🌧️ AMBIENT SOUND MIXER
Layer rain, ocean waves, soft wind, distant thunder, forest streams, gentle fire, fans, white noise, and dozens more sounds. Adjust the volume of each one independently. Build the calm that's exactly right — for sleep, study, meditation, or just life's louder days.
🎵 MUSIC PLAYER
Tap into a curated music library with full controls — play, pause, shuffle, repeat, speed adjust, and a sleep timer. Your favorites are always one tap away.
🗣️ VOICE & GUIDED AUDIO
Bedtime stories, meditations, breathing guides, and more — with the same calming interface as the music player. Mark favorites for quick access.
💾 PRESETS — YOUR CALM, SAVED
Build your perfect mix once, then save it as a preset. "Sleep," "Focus," "Rainy Morning" — whatever you need. Switch between them with a single tap. Export and import your presets to share or back them up.
