A French app named JveuxDuSoleil, created by Jean-Charles Levenne in 2020, uses sun-positioning algorithms and building-height data from OpenStreetMap to identify sunny terraces in Paris. The app, designed to help users find sunlit spots in the city’s narrow streets, has gained popularity this year, with nearly 20,000 users in one week in March following France’s darkest winter in three decades. It is community-driven, allowing users to suggest new locations or report inaccuracies. Parisian terraces, considered a key part of social life but declining in number since the 1970s, benefit from this technology that highlights sun exposure in real time. Levenne maintains the app without profit, covering server costs himself. Experts note the app’s role in preserving terrace culture amid challenges like rising rents and changing habits. The app works globally but is mainly used in Paris, where terrace culture is central to social life. (Updated 21 Aug 2025, 18:34 IST; source: link)
