Reddit users thevincentasteroid and MMD3_ posted about an auto-playing video ad (with sound) on the home screen. The ad is for Chicken Tender Wraps from Carl’s Jr. When it begins auto-playing, it pushes all the other UI elements out of focus and goes almost full-screen, returning to the home screen after it has played through once.
I’m not sure what app feature parity you are talking about, unless it’s a specific application for android(?)
For what it’s worth the Apple ecosystem is the “popular/trendy” one and businesses will cut their balls off to have their app work well on Apple stuff. I say that entirely from a “Apple is the zeitgeist” not one is better than the other standpoint.
