Help installing on iOS please

Please help, I get this error when I try to use the command: curl | gpg --import

command not found: gpg

Any advice appreciated as I’m trying to get into DeFi but its hard if you not overly tech savvy

I avoid macs, but you need to install gnupg tools to have gpg functionality if you miss that out of the box, this will let you verify that the installer file has been indeed signed by an official bisq contributor.
Installation will work anyway even without verification, doing the latter is best practice anyway
