Building web services and smartphone apps, which is most of what I’ve been doing professionally at HappyFunCorp1 for the last decade or so used to be pretty straightforward. Not easy, but straightforward, especially when the client was a consumer startup, which so many of them were.

The more we did the better we got at it. Design and write two native apps, usually iOS first and Android second. Don’t skimp on the design. Connect them to a JSON API, usually written in Ruby on Rails, which also powered the web site. There’s always a web site; consumers might only see the side which is a minimal billboard for the app, but there’s essentially always also an admin site, to control features and aspects of the app.
