i don't think the target audience of this app wants to think about being a "dead man", or dead anything, when this app would be useful. It's a fun nerd term, but if your life is actually in danger it's far from where your mind wants to wander, even though it's technically correct.

>a fun nerd term

It absolutely isn't. Lots of things have dead man switches, like locomotives and heavy machinery, and they're named as such.

Nerds work on locomotives and heavy machinery too. Those hard working folks are smart also. Unless your talking in a pirate voice, this is a nerd term for anything that kills something instantly.
