My 2c Marks: it's not much about technical capabilities as much as discovery. The difference between a PWA and a native app may be slight, but users notice. Throw a wrapper like Capacitor around the PWA and publish it on Zapstore (and as a standalone APK), lift is small, an agent can get it done for you in no time.

iOS users spend more money on apps for sure, it's a different demographic, but that seems to apply to paywalls and IAPs. Companion apps i'm not sure sure.
