Chat app for a church

The app should allow guests of a church service cerimony to previously see who else is going to be in the service. It is like a small social network among friends and all guests have access to photos and a small description of good acts of each other. They can “like” good acts of other guests and when two guests like each other's act, they match and can start praying together in a chat. In the church during the service, each one is informed by the app when a matched person is near. The only way to sign in the app is through a Facebook account. Logged in users will have 4 basic screens: 1) Home screen or “Quem vai tá”: Is the screen where photos of others guests can be scroll down and up. Clicked photos show more details. 2) User profile screen: User can add his photos and general infos about his own good acts. 3) Events screen: User can add the church services he intends to attend and choose the services he wants to see the guests that will be there. 4) Chat screen: A regular chat app as many we see. Here only matched guests can talk to each other. There will also have standard screens as, menus, inviting friends, like in Facebook and Playstore, blocked people list, help, cancel the account, tutorial, contact us, FAQ, User agreement. We also need a database to store all data about users and the use of the app I have all the JPG drawings for the screens. The app can be Android or Iphone or both I need you to install it on my server and provide all the code so that I can compile it if I need. Kind regards, Luc
