Has anyone used the Affluences app while traveling? I read a suggestion somewhere to download it to get wait times in Paris. It states “The app that lets you know in real-time how busy are hundreds of partner institutions.” We will be in Paris in March and wanted to know if this app is worth using. It states it “installs sensors in partner institutions”.
I also downloaded the Tupuy app for the free Sacre Couer tour. Has anyone purchased any of their other Paris tours?
