Lulu Light is a mobile sleep app that uses your phone’s camera flash and immersive audio to help you fall asleep fast. By emitting specific light patterns and sounds associated with Delta and Theta brainwave frequencies, it is designed to induce a hypnagogic, dream-like state through closed eyes. The experience includes modes for power naps, a jet-lag manager to shift your body clock, and shared sessions so you can sleep with friends and stay accountable.
