This is a design exploration for a mobile air quality monitoring app that aims to help users stay informed about environmental conditions in real time. The interface displays clear air quality index (AQI) readings for both indoor and outdoor environments, along with health recommendations and visual indicators for easy interpretation. I focused on delivering a clean, modern UI with a night-mode aesthetic, ensuring both readability and visual appeal. The goal was to create a user-friendly experience that empowers individuals to make healthier daily decisions based on air quality data.
