Signal has open sourced clients with reproducible builds (on Android) and their encryption library has been reviewed by multiple 3rd parties to great acclaim.

PGP lacks forward secrecy, meaning if a key does get compromised all of your past correspondence is now also compromised.

This solution works then, right? So given this implementation (and not a play store or ios download), one should be safe from xzy snooping?

Edit: As someone that has heard of forward secrecy but not how it relates to pgp, these were helpful reads:
