Information about older adults’ everyday journeys and outdoor activities can provide insights into their travel habits, leisure preferences and other daily activities. In this research, a smartphone-based mobile application was developed as a tool to better understand such daily activities of older persons who reside in Bukit Panjang Town, Singapore. The Chapter delivers a detailed methodology of the mobile application data collection, which includes device location information (GPS coordinates), background noise, background light level, and device battery level. Using analysis in MATLAB, heat maps were used to visualise the gathered insights. The findings showed that older participants tend to visit and spend their time mostly in their local neighbourhood whereas the visits to places outside of it are mostly done for shopping, religious and healthcare purposes.
