La Soundbox Les Visiteurs is a lifestyle application for Android devices developed by Useless Industries. It is a complete soundboard that features more than 60 sound clips from the movies Les Visiteurs and Les Couloirs du Temps. The sound clips are presented in an elegant and easy-to-use interface, making it simple for users to find and share their favorite quotes.

The app allows users to share their favorite sound clips with friends via WhatsApp, SMS, or Facebook Messenger. It also features a mode for using sounds as alarms or message alerts, as well as a Maracas mode that activates sounds by shaking the phone. Additionally, the app has a magical mode that plays a random sound when the phone's sensor detects the user's hand passing over it (requires a presence sensor).

La Soundbox Les Visiteurs also has a dark theme that can be set to automatic or manually adjusted (requires Android version > 10). Users can add as many widgets as they want to their home screen and suggest missing sounds to the app.

Overall, La Soundbox Les Visiteurs is a must-have for fans of the movies Les Visiteurs, Les Couloirs du Temps, and anyone who enjoys a good soundboard application.
