This project compares Kuala Lumpur "before and after" through a mobile application. The app aims to show how places in Kuala Lumpur have changed over time as the city developed, such as the original site of Masjid Jamek where Kuala Lumpur began. It also aims to educate younger generations and tourists about the city's culture and heritage. The app allows users to view different visuals of selected locations as they were in the past compared to the present.
