This project is solving the Transient Watch – Daily News on Active Neutron Stars and Black Holes on Your Mobile Phone challenge.

This is an android application contested for NASA App Challenge. This application notifies interested astronomers with 'daily news' on the transient high-energy sky, based on information available from public pages at NASA, the European Space Agency, the Japanese Space Agency, etc.

The app collects information from a webpage(similiar like NASA resources) that has json-formatted data. At first, a script, resided on our sever checks whether there is any update of the previuos data of that webpage. If it finds any update, then it auto-generates a notification and a news featuring that update of the specific content.

In this way, all users who have installed this application are notified about the update of a content via a notification message in their corresponding android devices. And that notifications redirects himself/herself to the details of the update information of that content inside the application.
