Nuro Pro is a private in-browser audio engine for developers, students, and creators. Instead of relying on repetitive focus playlists, Nuro Pro lets you play your own local music while layering real-time binaural beats (Delta to Gamma) and sound-masking noise (brown, pink, white) underneath. Features session timers, clean light/dark themes, and runs 100% locally in Chrome & Edge with zero tracking or RAM bloat.
