Get the app
Your visit, your audio guide, and your QR access — in your pocket, offline-ready.
The Notre-Dame Companion apps for iOS and Android carry everything from your purchase: My Visit, your reservation QR, the audio guide and history series, the interior route, the nearby map, and the practical checklist.
Audio downloads are offline-ready, so the guide keeps working inside the cathedral’s thick stone walls — no signal needed.
The apps are launching alongside the service. Until they appear in your store, everything is available on the web at the same address — sign in with your booking code or email.
