android app for tracking and comparing friends running distance

I need a simple app for my group of friends. This app will allow the users to register an account with password. Users can then key in the following fields: - date (default current date) - time ( default current time) - distance ran - time taken - location - total accumulated distance( from a file on a website) The data will be uploaded to a text file / msql database. The next page can see all the users, sorted by who has the highest accumulated distance.. This app just need to create the app. The budget for this app is $30 to $80 The web site with msql or text database will be provided
