M1 native apps obviously won’t be intel compatible. During the transition period, you can expect most big developers to release x86 version of their apps. But after the transition period, id reckon intel based macs will lose app support way faster than PowerPC transition era.
Edit: oopsie. iPad section. 😂
If that’s the case, “native M1 app” is kind of a flop, as iOS app is pretty much “architecture” agnostic (there’s only one for recent devices). But if news apps are developed after September, then I think they will become native M1 app. But optimised M1 app is another matter.
