There’s no need to do this, as Discourse looks fine on mobile. Recreating the app entirely to provide a native app experience would be reinventing the wheel for the sake of doing so.
I believe @nexo and @waffleslop were inquiring basically about a fullscreen webview.
Note that FULLSCREEN flags aren’t possible with Discourse; it breaks the reply system. I inquired in a separate thread, and was told off, saying my idea was stupid. A week after release, hovering at nearly 50k downloads.
I currently have my forum on an iOS and Android app, and used a Webview and WK WebView in Android/iOS respectively.
iOS is a complete mess to deal with, Android was seamless. Both apps together, took about 30 minutes to convert into WebViews.
I did this to create a premium experience for my users, even if it is just tapping a button and opening what is essentially a browser window without a URL bar, it offers a better experience, which is what I wanted.
If anyone is looking for some help DM me, I’ll let you know how I did it.
The app itself (programming) takes 30 minutes tops, the signing for iOS takes hours. Android takes about 15 minutes from scratch.
