Por que ninguém desenvolveu um aplicativo Android de código aberto?

Is it possible to convert a forum into a real app?

The easiest thing you can try is deploying a TWA based on a PWA for Android. It’s really simple; it’s essentially publishing a PWA on the Play Store with official tools. It’s a more involved process for iOS, especially because of the review process, but you can also use something like PWABuilder or a similar tool to help publish your web app there. Both are just web views which will work almost the same as an installed PWA.

Acho que isso também foi discutido aqui há alguns anos Discourse sites in Playstore
