NightFlow helps you fall asleep to TV without leaving it on all night. Start the app, lock your phone, and watch as usual. When your show ends or your TV goes quiet, NightFlow detects the silence and gently fades in calming nature sounds so you drift off without a jarring stop or awkward gap.
Built with privacy in mind, NightFlow processes audio locally on your device and is designed for bedtime with a dark, glare-free experience.
