Its just dating ios/android app similar to okcupid, in smaller simpler scale.. I prefer if someone has already worked on similar project and just fork out of that..
- user registration with photos & profile questions
- search/browse other profiles and give 0-5 stars ratings..
- pm messaging
- answer list of questions to improve the match (like: do you smoke? do you like horror movies etc..) .. I will make the list of questions..
- server side code needs to be php/mysql
