Stop Demarchage is a productivity application designed for iPhone users, focusing on enhancing user experience by blocking unwanted commercial and advertising calls. The app effectively blocks 12 million phone numbers classified by ARCEP as telemarketers, ensuring that important calls from delivery services and customer support remain unaffected.

The application offers a straightforward and user-friendly interface, allowing users to block these intrusive calls without the need to share personal data. Once set up, the blocking feature operates seamlessly in the background, eliminating the need for users to frequently reopen the app. This allows individuals to concentrate on their priorities without the distraction of unsolicited calls.
