A small exploratory study testing the use of a walking-specific app (Go Jauntly) for the analysis of associations between walking environments and perceptions. The study was conducted in the Global South (Buenos Aires, Argentina) and the Global North (Bristol, UK and Auckland, New Zealand). This was a collaboration between three universities (UWE, Auckland University of Technology, and Universidad Nacional de San Martin in Buenos Aires Argentina) and two private companies: Go Jauntly (developing the app) and Tranquil City (providing data analytics). The project was funded by the Volvo Research and Educational Foundation (VREF).
