Thanks for explaining. So basically - this app acts like a concealed/plausibly deniable dead-man's switch with the capability of contacting third parties who might be able to help if the phone is taken away/destroyed by the abuser. And the reason the action isn't taken immediately is that it can take some time to set up a proper "escape" - but if critical, this can be expedited.

That makes sense now. It's not immediately obvious to a newcomer.
