SleepSound Pro transforms your phone into a powerful sleep and relaxation machine, generating 10 beautiful ambient soundscapes entirely through real-time digital signal processing — no audio files needed. Whether you struggle with insomnia, need to focus during work, meditate daily, or simply want to drown out distracting noise, SleepSound Pro crafts the perfect audio environment for any situation. **10 SCIENTIFICALLY-CRAFTED SOUNDS** • White Noise — Pure, flat-spectrum noise that masks all environmental sounds. Perfect for light sleepers and those sensitive to sudden noises. • Pink Noise — A naturally balanced spectrum that mirrors sounds found in nature. Studies suggest pink noise may enhance deep sleep and memory consolidation. • Brown Noise — Deep, low-frequency rumble reminiscent of strong winds or rushing water. Beloved by those who find white noise too sharp. • Rain — Gentle rainfall with realistic amplitude variation, bringing the calming rhythm of a rainy afternoon indoors any time of day. • Ocean Waves — Two overlapping wave patterns create the hypnotic ebb and flow of the sea, perfect for coastal relaxation without leaving home. • Forest — Light ambient background with occasional birdsong bursts, recreating the peaceful soundscape of a quiet woodland morning. • Fan — The familiar, steady hum of an electric fan. Consistent and comforting for those who sleep better with mechanical white noise. • Fireplace — Deep, warm crackling fire sounds with realistic random crackle events, creating the cozy atmosphere of a winter evening by the hearth. • Thunderstorm — Immersive storm experience combining heavy rain with distant thunder rumbles, for those who find storms deeply relaxing. • Café Ambience — Warm, mid-frequency background noise simulating a busy café environment, scientifically shown to boost creative thinking and focus. **ADVANCED FEATURES** Mix multiple sounds simultaneously to craft your perfect soundscape. Combine rain with cafe noise for focused work, or ocean waves with brown noise for the deepest sleep. The Pro mixer gives you individual volume control over each active sound. Save your favorite combinations as custom presets — your perfect "Deep Sleep" or "Focus Mode" mix is always one tap away. The sleep timer automatically fades your sounds out over 60 seconds before stopping, so you drift off naturally without abrupt silence. All audio plays in the background, so your screen stays off and your battery stays healthy throughout the night. **PRIVACY FIRST** SleepSound Pro never requires a microphone, never records audio, and never needs an account. All audio is generated locally on your device. Your sleep habits are yours alone. **FREE & PRO** Try SleepSound Pro free with 3 sounds. Upgrade to Pro for all 10 sounds, the advanced mixer, custom presets, and unlimited sound combinations. Choose monthly or annual billing, cancel anytime from your App Store settings.
