WHY SAEGE • Adaptive Sleep Sounds Three balanced layers: immersive ambient environments, scientifically tuned binaural beats, and a warm low-frequency drone. Built for deep listening, all night long. • Smart Sleep Tracking Motion and microphone analysis detect sleep onset, distinguish movement from rest, and map your journey through Light, Deep, and REM stages. • Beat-Aligned Smart Alarm Wakes you during your lightest sleep phase by gradually shifting brainwave frequency from Delta to Alpha. Wake naturally — never jolted. • Immersive Sound Environments Ocean, Forest, Deep Sea, Rain City, Space, Temple, Frequency. Each with unique tonal variations and visual ambience. • Visual Effects Particles, Aurora, Breathing Orb, Ripple, and more — calming visuals that respond to your sleep depth. • Breathing Guide (4-7-8) Activate your parasympathetic nervous system with proven breathing patterns to slow your heart rate before sleep. • Morning Report Sleep score, timeline of detected events, trends over time, and Apple Health sync for a complete picture of your rest. THE SCIENCE Binaural beats use two slightly different frequencies in each ear. Your brain naturally synchronizes — a process called frequency entrainment. Saege guides your brainwaves through the natural sleep arc: Alpha (10Hz) — Relaxation Theta (6Hz) — Drowsiness Delta (1.5Hz) — Deep sleep Best with headphones. Monaural mode is also available for speakers. PRIVACY FIRST Your sleep data stays on your device. Nothing is uploaded, sold, or shared. Optional Apple Health sync only if you choose.
