What's an example of a government app

In Australia: Centrelink, Service Victoria, Medicare, myID (formerly MyGovID), ATO (tax) — for a start.

There's no great reason for these to be Android/Apple specific. I'm just offering examples as requested.

Portuguese government app: https://play.google.com/store/apps/details?id=id.gov.pt

Allows you to have a digital copy of your ID and sign in to government sites/services (there are alternative methods).

ROeID app, which is required by almost all RO government websites to log in.

Identity apps as well as apps to access government and social programs.

Not to mention why specifically government apps? Would those not be covered by general compatibility with web standards?

Wouldn’t well designed mobile web-apps suffice for that use case? I have several web-app site shortcuts linked on my Home Screen which behave just like the native apps. In most cases I don’t see why that would not be sufficient, including most “government apps” use cases
