Changes: app for change detection between 2 photos of the same scene

Hi,

I wanted to report the release of my new application: Changes.
It can detect changes between 2 pictures of the same scene, as a book from the library has disappeared, the crack in the wall got bigger, the plant has grown, the workers have made good progress. It is perfect for cheating on the 7 differences game:

This application is a real innovation, it brings a service that did not exist in the world of smartphones.
