This application allows to control any change on a web or url. In the main view, the list of pages to control is showed with the current situation (green for small changes, yellow for medium changes and red for a lot of changes) and a label indicating that the control has errors (this could happen if no internet connection is available) or if the item is disabled. The user can set the sensitivity of the changes, the period of control for every single page or can disable the control temporary.
For a given item is possible to visit the site (or url) or reset the current situation to "small changes". At any time the user can refresh all the items without expecting that the period of control launches the verification.
