Hey everyone. So I am almost done with my second book on ios and objective-c and am about to start my first app, so I have the knowledge to code apps (hopefully ). I had an idea today to make a social networking app that kinda combines yelp and twitter in a way (if you need more info to help me with my problem I would be happy to expand). Before I spend time planning this out, I was wondering what equipment I would need and what it would cost to run this app and make it. Google hasn't really helped me so far, but a random guess would be I would have to buy a server. Any help would be appreciated and if you need more info just ask. Thanks in advance!
