At first a new user needs to sign up and then log in. SoSporty is an mobile application which aims at the residents in Southampton thus after a user logged in, this app will automatically locate the current position of the user (if the user doesn’t open the locating function, he won’t be able to see the activities around him).

On the main page of SoSporty, the user can see all activities showing as red pins which happen today around him. The user can view brief information by clicking on the pins. The user can also search for activities which attracts him and choose to join some. Of course he could also organize an activity by himself and then wait for others to join or invite his friends (if he has any) to join in. If he doesn’t have any friend, he can also add new friends by searching their names and then he would be able to chat with his friends privately or share videos or photos with them.

Before the activity is finished, all participants in it can chat with each other in a chatting room, with fake names randomly allocated by the system, which aims at protecting the privacy of users. A user can also invite his friends that he already added to the activity.

If the user is not satisfied with the activity he has joined, he can quit it before the date when the activity happens.

When the activity is over, all participants need to score each other as well as the organizer.

The user can also edit his profile including the nickname, email or password, and view some notifications.
