I tried mosh years ago, but ended up settling on "ShellFish" by the same guy who wrote "Working Copy". It can reconnect if you use a tmux session, and it has the ability to preview remote files and interact with the Files application on iOS (presenting the remote filesystem in Files).
I used to heavily use Blink Shell, but a combination of changes to their application and also that ShellFish + Tailscale is so easy and reliable made me switch entirely to ShellFish as well.
I also enjoy the ability to quickly launch/manage Digital Ocean instances useful sometimes as well.
