With Syncthing my smartphone and PC would be perfectly synched (from what I know), but isn't exactly what Immich does.
With it you can remove photos one your phone and still view them when the PC is on
I know how to use docker (a bit) and I have already installed Immich with it some time ago, but it would be nice to have an easier alternative, especially for less tech inclined people
It means we're doing something right.
