The US is the only place it is available (or so it was reported a few days ago).

I was able to download it from the US App Store: https://itunes.apple.com/us/app/paper-stories-from-facebook/...

It won't come in the search probably, but if you go to the page for the Facebook app and click through to Facebook, Inc. you'll find it in their apps.

For me it was just hard to find.. had to look for "Related" apps under the main FB app.

and iOS 7 only. But I guess there aren't many others out there whose iDevices don't support the upgrade.

Does anybody know their strategy here?

It can take time for apps to propagate through the App Store once it goes live. It is not a 'flick a switch and the app appears everywhere' process.

Not available in Germany either.
