The app makes the content look good, and it supports offline reading. But I don't see why it requires an app at all. It seems like I should be able to subscribe using my RSS reader or Google Play Newsstand, which are already on all of my devices. Because I have to go out of my way a bit to read the content, I browse it a lot less often than I'd like to.
The app itself is well designed, but the content won't download on my Galaxy S5. I ended up going to the site in my browser to read the content.
Great content, good to have it on Android.
