Ohh, then that is exactly what Amethyst does. I thought you had discovered some magic :)

when I open amethyst without internet it doesn’t work, i don’t think its the same ?
The ui is only based on local subscriptions, remote connections only dump data into nostrdb
We don't have the disk db, but there is a full in-memory relay that all screens pull and save to before reaching for externals. And when the externals bring new info, the reactive flow will update each intermediary cache until it reaches the screen and updates it. Since Android doesn't kill the app that frequently, the cache just stays on for days or weeks in some cases.
the disk db is nice so you can still use all your apps while your internet is down, but this might only be useful if you are building a microapp browser.
It's only useful if the app is getting killed too many times. Otherwise, in-memory relay does work offline too ( albeit we never really focused too much development on it ).
In most normal cases, Android will put the RAM of the app in zRAM to free memory for other apps and recovering that when the user brings the app back from background.
My heavy user for instance only sees an app restart with clear db once a month or so.
