The project
NOX is a revolutionary social alarm clock that transforms the morning wake-up experience. Users wake up every day to exclusive videos (noxs) created by friends, family, and favorite creators. The app combines an alarm clock, social network, and video feed to create a unique and engaging experience where users can wake up the world with their creative content.
The app offers: • Social alarm clock with automatic playback of noxs upon waking • Infinite scroll video feed to discover community content • Nox creation with music, filters, stickers, and GIFs • Interactive map to discover and wake up users nearby • Instant messaging to connect with other users • Dreams (24-hour disappearing stories) to share daily pursuits • Personalized wake-up experience with content selection • Global creator community sharing concerts, sports, news, and life moments • Profile customization and favorite nox sharing • Discovery of thousands of new noxs created daily
