Right, and I bet the experiment was to figure out how many people would notice the missing email, and either complain, or start visiting the site more often. Of course we'll never know if most people are more like you, or would actually go to the site daily, if it weren't for the email.
I don't have the app on my phone, so either (1) they didn't notice that, or (2) they wondered if losing the digest would make me install it (guess not).
I think the app is what's supposed to make their site "sticky."
