Nook. is an entry to the 2026 Western Founders Network’s Product Design Sprint (PDS). In response to the theme "A Look Back Into 2016", the app strips away the addictive mechanics of modern social media feeds and replaces them a nostalgic, widget-based personal profile. We ideated, conducted user research, created wireframes, developed the brand and visual system, and built the final hi-fi interactive prototype all within 24 hours.
