It's not market share - it's revenue, demographics, usage patterns, and time to market that encourage iOS first over Android. While it is true that Android crushes iOS on global market share, the other factors are reversed in iOS's favor. For example: http://www.businessinsider.com/ios-android-shopping-2013-12 http://www.businessinsider.com/ios-android-shopping-2013-12 Intuitively, this makes a lot of sense. Many Android phones are substantially less expensive than comparable iPhones, and thus act as a stand in for an old Nokia or Ericsson. Those users that purchase inexpensive Android phones often aren't using it as a smartphone - it's just the free or cheap phone they get with their contract, and the use it as a phone first and foremost. This is in direct contrast to the iPhone, where Apple's advertising de-emphasises the "phone" part of the equation. This is further evidenced by the fact that expensive Android phones see comparable (or better!) engagement as compared to iPhones: http://info.localytics.com/blog/top_of_the_line_android_phones_show_40_percent_higher_engagement_than_iphones http://info.localytics.com/blog/top_of_the_line_android_phon... Also, keep in mind that the HN crowd is mostly interested US/Valley companies. Mobile market share numbers in the US are very different than global market share numbers, which leads to a lot of iOS first development in the US: http://www.comscore.com/Insights/Market-Rankings/comScore-Reports-January-2015-US-Smartphone-Subscriber-Market-Share http://www.comscore.com/Insights/Market-Rankings/comScore-Re... Hence why so many apps on HN seem to be iOS first. All of this having been said, if the rising trend in Android revenue and engagement keeps up, along with the improvements Google is making to its developer tooling, it's likely that we'll see Android first start to happen. Some of this trend can be seen in the Localytics analysis above, though it isn't the whole story - App Annie's recent report is a great overview: http://blog.appannie.com/app-annie-index-retrospective-2014/ http://blog.appannie.com/app-annie-index-retrospective-2014/ While there will almost certainly be some lag-time between the time that Android first becomes feasible (e.g. now-ish) and businesses actually going Android first due to psychological biases, once it becomes the more profitable option companies will choose it. Until then, iOS first wins.
