It's always good before starting do design for any Apple product to have a quick look at their Human Interface Guideline (HIG) https://developer.apple.com/library/ios/documentation/userexperience/conceptual/MobileHIG/index.html https://developer.apple.com/library/ios/documentation/userex.... They have HIG for almost everything. I also read that a lot of apps are developed on iOS first http://www.businessinsider.com.au/app-design-company-director-all-of-our-clients-choose-ios-over-android-2012-7 http://www.businessinsider.com.au/app-design-company-directo.... I wonder if there's any truth to that. But saying that I know that Google is pressing their Material Design http://www.google.com/design/spec/material-design/introduction.html http://www.google.com/design/spec/material-design/introducti... quite hard lately. Would really love to hear what Android devs think of the Material Design. Are they going to port their current app design to it?
