Почему никто не разрабатывает открытое приложение для Android

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.

Думаю, это уже обсуждалось здесь несколько лет назад: Discourse sites in Playstore
