The current thesis aims to provide the best possible service to the clients visiting the IKA branches of Thessaloniki, while they are queuing for the various departments. The application allows users to issue tickets in any office / department, as well as office employees to inform users of their waiting time, whenever they serve a customer. This dissertation focuses in two main parts. The first one is the server and the functions it performs for the application, such as the storage of the database and the various calculations, so that they are presented to the user, i.e. the Android application. The Android application, which is the second part, deals with the appearance of branches / departments and the possibility of issuing a ticket to one or more of them, on the client's side, as well as the ability of employees to inform the users after the completion of their service. In conclusion, this application aims to help users who wish to visit any of the IKA branches without being physically present in the queue unless it is time to be served. As far as technologies are concerned, the application aims at new and popular ones, which are an interesting part to study
