Waiting Line Manager

This app was created to handle a situation like this: say a badminton club with 30 members in different levels, and the club has limited uncertain of fields for members to play, each filed can have maximum 4 members. Same level of members prefer to play together. After a game the members may return to the waiting line or leave, and members may be late or leaving earlier, and new members may join at any time.

So, the question is, how to handle this chaos and assure every present member has the same opportunity to play? That is what this app will solve.

To use the app, just follow the simple steps:

1, For first time, use the app's Add Member function to create the Member Database, member's name and level will be saved in the phone.
2, Use the Sign In/Sign Out function to sign in or sign out members
3, Click the filed to form new team and reload.

Members can sign in or sign out at any time when they are not playing.

Hint: create some temporary members in case that after the waiting line started, a new person come and want to join the club, and want to be in the waiting line immediately.
