Hey guys, I have a specification & mockups for an iOS app I want to develop (my 1st). It is a dating app similar to Tinder, Happn & Blendr, with a twist. I need to find a developer to finish refining the algorithm/dev plan with me, and then work with me to develop the app. I am posting the job on work platforms like oDesk/Elance. What skills do I need to specify in the job post to find appropriate developers? many thanks, Josh
