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 allows users to suggest new locations or report inaccuracies, making it a community-driven tool. Its popularity surged in 2025, with nearly 20,000 users in one week during March, following France’s darkest winter in three decades. JveuxDuSoleil helps Parisians find sunny spots in a city known for narrow streets and tall buildings, where terraces are culturally significant but have declined from several thousand in the 1970s–80s to just over 1,000 today. The app simulates urban shadows and highlights sunlit terraces, aiding users in securing sunny seating at cafes. Its creator maintains the project without profit, covering server costs himself. Experts note the app’s role in supporting Paris’s terrace culture amid challenges like rising rents and changing social habits. (Updated 21 Aug 2025, 18:36 IST; source: link)
