Coinbase recommending third-party iOS app

On Coinbase's official blog they recommend a third-party iOS app on the iTunes store. This seems a bit more lax on security than I would expect from a wallet provider.

The unofficial app on the App Store uses Coinbase's name and artwork, and doesn't say that it's unofficial [2]. It's seen updates since Coinbase's blog post, where the author could have added this but hasn't. I also wonder if they've been making sure that they're still willing to say that they believe it to be secure and safe to use after the updates.

This is concerning to me, as a Coinbase user.
