One of Signal's goals is to be proliferated in main stream applications (like Whatsapp) so hopefully those not savvy enough to use signal directly can benefit from the pressure that savvy users exert on Facebook and others to be reasonably confident in their crypto. Similarly, I've never personally verified that my version of Signal is the same as one that I could build from source, but I make the tradeoff that someone more paranoid than me would notice a widespread compromising of the app store.
