Thumbkey: A keybord with a vastly different layout designed for ergonomy. I’m realy happy about this one because the only atlernative was closed source.
syncthings-fork to backup my files
SD contacts on fdroid to export my contacts on change in a folder for syncthings to backup. ( I changed the code of this one to use only one file instead of several ones)
kde-connect: allows sharing notifications,
files, and much more between your phone and pc
Out of interest why do you use syncthing-fork?
not op but I use the fork too because there are more options and more control when it’s running. I have mine set up to turn on for 5mins every hour
