Think of it like this; you have a local relay on your phone that you post to. It keeps a record of all your notes local and at the same time blasts the notes out to the broader Nostr network. One of those relays that it blasts to is also yours but it keeps a record of the data public for others to find. This could also go for your blossom media, you upload to your local relay as a โbackupโ of your blob, and then it mirrors to public blossom server that other people can find.
Me personally (using Haven) I'd really like an WebUI for management (storage and stats mainly, like seen what's in Blossom and easy delete something with classic lists and checkboxes + eventual regex/query search) and a client built-in so one can deploy a single application and have all setup in a single shot: "just install Haven, go to localhost:port and start reading, publishing, managing your Nostr garden", the need of separate stuff kill newcomers interests IMVHO.
The client itself well, could be very rich, like a public blog face (long form), a Reddit/Lemmy-like face (short form), a contact manager for Nostr as a digital identity, a chat UI, tomorrow adding VoIP as a module maybe, than some long form became a Wiki, some short form tasks with a management UI like Vikunja and a step at a time "the modern personal web" became Nostr.
A long journey the humanity really need :)
When I try using the 'Mac Relay Sync' feature in the iOS app, I click the 'Sync Now' button. Then while loading it says 'Connection Error' and then I get the message 'Already up to date' after it finished loading.
Can you verify if that feature is supposed to work or not?
If I quit the relay on Mac, I get the same exact messages, so it does not seem to work for me.
