Mobile shiny app that runs offline, no connectivity

Question

I am trying to make a shiny app that can be used on a smart phone without connectivity.

I have found several examples of shiny apps being bundled into something convenient and run on a desktop or mobile device, but they all still require an internet connection. I want the mobile app to be able to run locally with no connectivity.

The closest thing I have seen is making a shiny app into a Progressive Web App (PWA). PWAs in general do have the ability to run without connectivity, but shiny PWAs that I have found still require connectivity.

List of similar resources:

shiny as standalone electron app (not for mobile) Deploying R shiny app as a standalone application
PWAs for shiny https://github.com/pedrocoutinhosilva/shiny.pwa
shinymobile - does create PWA https://rinterface.github.io/shinyMobile/

From what I can tell, all these and others still require internet connection, though.

Any options for an app that can run on a smart phone without connectivity?

Shiny apps run all your R code on the server. You cannot run shiny apps without a server, and you can't run a server on your smart phone. If you need to run without a connection to a server, shiny probably isn't the right solution for you. — MrFlick, Jul 15 '21 at 21:03

For an epidemiological cohort study, a Shiny app was developed to run completely offline in Android mobile devices. The app was designed for field level data capture. The code to setup the Android devices so that the Shiny app runs locally, offline, was published in GitHub, https://github.com/dmrodz/htrack. The installation_and_dependencies section contains the setup needed for the mobile device to run R (and the app) and deploy in the default browser (offline/locally).

The development of this app was peer-reviewed:
