Is There an Official Google Reader App With Widget? Does anyone know if there is an official app from Google for Google Reader?

I would like an official app with a widget that displays the number of unread feed items.

Good News! Google just added widgets to the official Google Reader App.
There is a dearth of official apps for google's own services on google's own mobile OS.

No official Google Reader App, no official widget.

That may be because they work on optimizing the mobile versions of those web-services, to obviate the need for an additional app. You've already got the browser -- why install an app for a web-service?

This 2008 article on how gReader renders in mobile webkit might explain some of the concept.
