    My application is a social network of a different variety. It is a sort of "matching website", similar to dating websites, but with the goal of finding genuine friends that share common interests, vicinity and overall compatibility. This application is not a dating website, it is not for professional growth, it is not a time waster. It is to create genuine friendships. It will be most beneficial to individuals who are new to a city, post college, busy with work, relatively introverted, married/don"t go out much, etc. The long term goal of the application is to have subsequent Android and Web based applications, but to start, iOS will be the main platform. The application supports the creation, management of groups, events, profiles, internal discussion boards and private messaging. Most importantly and the crux of the program is that the application implements a complex matching algorithm based on interests and the user"s answers to questions. This algorithm will operate in a way that is different from traditional matching and will "weight" questions based on their importance. I will come up with the questions for the matching algorithm. The freelancer that wins the bid will only have to put the questions into the matching algorithm in such a way that it will generate matches.The application has pretty much all of the designs complete, with screenshots, storyboards and picture files. The entire functionality of the application is mapped. It just needs to be coded and implemented.Monetization: - Ads running on select screens. Ads can be specific to user responses. - Exclusive content (may not be implemented until application has been running for awhile). - Sponsored accounts, etc. (may not be implemented until application has been running for awhile). The winning Freelancer should have the ability to, once the iOS app is running and turning revenue, implement the app in Android and later, web. The winning freelancer should also be able to setup the host server, most likely on Amazon AWS, should be able to setup analytic tools, such as Google analytics or Flurry, should provide support services to protect the application from operating system bugs, provide updates, keep the code running smoothly, etc. for at least a year after the application is complete. FREELANCERS SHOULD NOT BID ON THIS IF THEY ARE INCAPABLE OF COMPLETING THESE TYPES OF MATCHING ALGORITHMS AND COMPLEX APPLICATIONS. I HAVE ALREADY TAKEN THIS APPLICATION BACK FROM A DEVELOPMENT COMPANY THAT HAD NO BUSINESS UNDERTAKING THIS PROGRAM. ALSO, IN THE FREELANCERS BID, PLEASE MENTION ACKNOWLEDGEMENT OF THE REQUIREMENTS OUTLINED IN THIS SOLICITATION.

    This is a social sharing platform that touches on social responsibility, politics, and cultural items that are shared among followers of users. Trending stories/photos are available for viewing and users can share on Facebook and possibly Twitter. The concept is easy but the overall build may be moderate to difficult because it will require servers running user settings and content as well as giving feedback to the user.

    We are looking to get a mobile application developed for both the iPhone and the Android OS. We have a well thought out application that will require creating user profiles, chats between users, group chats for multiple users, geolocation, and a matching system between groups. This application will also require some proper database creation and management to handle the back end for users and other stored data. I apologize for not explaining the application in full here, but will require the developer to sign an NDA before we can disclose all the details. We are looking for a single developer who can do both iOS and Android, as we don&quot;t want to use one developer for each OS and complicate everything.We have a large budget depending on what all you can offer us, and would like to see the full mobile application completed within 120 days.
