Without boring you with the specific data and numbers (though if you’re interested, we posted a link below), the fact is that Apple’s iPhone iOS and devices running on Google’s Android each make up a significant portion of the total market share, and neither is likely to vanish any time in the near future. So, if you’re looking to create a mobile app, the smartest move is to accommodate both of them.
Without getting into the technical nuances of iOS and Android, the fact is that both have their own distribution methods, and many apps are not compatible for both. If your app isn’t compatible with both iOS and Android, many of your potential users will never be able to find your app, let alone use it.
