Halcyon: Brown & White Noise

Halcyon helps you fall asleep, relax, and focus with soothing sounds you can mix your own way — plus wind-down programs, narrated sleep stories, guided relaxations, and breathing exercises to quiet a busy mind.

MIX YOUR PERFECT SOUND
Layer any of 39 high-quality sounds and set each one's volume to build the exact soundscape you like. Rain over a distant campfire. Ocean waves under soft wind. A fan with gentle night crickets. Save your favorite mixes and bring them back with one tap.

• Nature — rain, light rain, heavy rain, rain on a roof, window, or tent, wind, campfire, night, storm, forest birds
• Water — ocean waves, gentle shore, rolling waves, shore break, stream, waterfall
• Noise — white, pink, brown, grey, green, and blue noise, with a short guide to how each one differs
• Comfort — fan, heartbeat, air conditioner, tumble dryer
• Ambience — airplane cabin, night drive, café, train
• Pulses — Delta, Theta, and Alpha Pulse, headphone-free pulsed tones for a steady rhythm
• Frequencies — five binaural tones for deep sleep, meditation, relaxation, focus, and clarity (headphones recommended)

GUIDED SLEEP & CALM
• 10 sleep and relaxation guides — wind down, body scan, letting go, and more
• 20 original sleep stories written to drift you off — narration is now available for 18 of them in a choice of four calm, natural voices, with more stories gaining narration over time
• The Riverboat includes narration in all four voices without Premium
• 3 wind-down programs that ease your whole mix back, layer by layer, to quiet
• Box, 4-7-8, and coherent breathing exercises to slow your breath and settle your mind

BUILT FOR SLEEP
• Sleep timer that fades gently to silence — it won't jolt you awake
• Save a timer with any mix, or set a default timer that starts whenever you press play
• Background playback keeps sounds going with the screen off
• Lock-screen and Control Center controls
• Optional: play alongside other apps — keep rain going under a podcast, audiobook, or music (Lock Screen controls are off while this is on)
• Siri Shortcuts to start a preset, a saved mix, or a sleep story
• Back up and restore your mixes, favorites, and settings with a file you save or email yourself
• A calm, dark interface designed for the end of the day
