Most sleep apps play nature sounds or tell stories. Somnolent uses science. We ported our top-rated VR sleep technology (72% efficacy) to mobile. Using hypnotic audio-visual entrainment and binaural beats, the app mimics your brain's sleep frequencies to heavy your eyelids. It features simple, slow, pulsing visuals, a soothing, slowing heartbeat, hypnotic narrations and binaural beats that down-regulate your nervous system.
