SleepGuru is a 2-layer audio mixer for sleep. Combine any two sounds — stories, meditations, nature sounds, frequencies, kids content — with independent volume controls. Over 2,000 possible combinations.
I built this because I got frustrated with apps that made me choose. Now I fall asleep to rain + a sleep story, or ocean waves + a meditation. Whatever works that night.
Works offline on iPhone, iPad, and Mac. New content added weekly.
