Nature sounds for a calm night. Sleepgod is a relaxation app that layers binaural beats over soothing nature sounds. Waves on the shore. Wind drifting through a forest. Soft rain on a quiet night. Choose tonight's sound, put on your earphones, and let the night settle in. Features: - 9 sounds: 8 carefully selected high-quality nature sounds plus a vibraphone ("Ocean" is free for 7 days; unlock everything with a one-time purchase) - Binaural beats layer with independent volume control and on/off - Sleep timer (15-90 min) with gentle fade-out - Wake-up timer (15 / 30 / 45 / 60 / 90 / 120 min) — at the set time, a gentle alarm plays over the nature sound - Background playback - Dark, night-friendly design About binaural beats: A listening experience created by delivering slightly different frequencies to each ear, producing a gentle "beating" sensation. Our binaural beats are designed around frequencies based on just intonation, known for its beautiful resonance, and gradually guide you into the beating. Let yourself rest in the beating and the subtle fluctuations, and feel a deep sense of relaxation. Stereo earphones or headphones are recommended. This app is intended for relaxation and is not a medical device. Please use at a moderate volume.
