&gt; So I think your point, while valid, does not apply in any way to Xamarin!<p>I&#x27;m afraid GPs point is still valid - UX (the experience) is more than just native&#x2F;native-looking widgets, but how the app conforms to platform conventions. For example, iOS apps typically include(d?) a back button at the top left corner; even if the button is rendered faithfully as an Android widget - that app will feel alien on Android (it was also an easy way to spot lazy iOS &#x27;ports&#x27;). I think edge-swipes are another iOS convention for navigating back&#x2F;forward, which would be foreign on Android, so I fully agree with GPs statement: Each platform requires UI work to make it really fit the platform in question
