I use termux to ssh and RealVNC to connect to a remote vnc session, all over a wireguard VPN.
Also Syncthing to automatically sync files between the phone and my home server. I download podcasts and audiobooks into a folder on the server and they're automatically on my phone ready to play.
Immich to connect to my self-hosted media. And ntfy to get notifications from my home stuff.
Tasker to automatically activate my wifi hotspot for the car's Android headunit when it sees the car's bluetooth.
I have another tasker job to take the 2-factor authentication numbers from SMS and forward them to ntfy, so I don't even have to look at the phone, I get a popup on my PC with the 2-factor code.
And the best of all, Firefox with uBlock Origin add-on and Revanced Apps. Because ads are cancer.
And I still have a headphone socket.
Can all that be done on iOS?
