If you create a link to your hosted TW file (which can be hosted on your own device, tiddlyhost, tailscale connection, etc.) in the Android app “Markor”, then when you preview your page and click on the link, your page is loaded in a special single-page viewer provided by Firefox. You can save from this page back to your host.
The advantage is that you don’t have to wade through the dozens of tabs that the full Firefox gives you, and you can make your own personal menu back in Markor.
Couple this with the browser storage plugins (the official one and the Btheado opinionated one) and you have something very close to a full TW application.
