Moonrain is a free, offline sleep-sound mixer iOS app that lets users blend up to four ambient sounds, use a sleep timer, guided breathing, ASMR, meditation timers, and a gentle alarm, all without accounts, ads, or tracking. It stands out for its privacy-first, fully offline design, widget/Siri integration, and shareable sound mixes, though it occupies a well-trodden category of sleep apps.

Target audience: iOS users, people with sleep issues, meditation practitioners, parents, remote workers seeking focus
