Thank you guys. I’ve been using LocalSend for a year or so, and recently I noticed it’s Documents & Data is over 1 GB on my iPhone.
To me, that means that there’s some cache you cannot remove (the only way to clear that on iOS is to remove the app: I have just tried that, and it solves the issue).
I thought KDE Connect is more bloated. Turned out, it’s just 8 MB; and it has the ability to clear cache. All my computers are on Linux (Gnome or sway: perhaps that’s why I forgot about the KDE Connect), and I thought hey, really, why not!
So, as someone who used LocalSend for a long time: it does the job, but KDE Connect is just better, it turned out.
