Pretty good but one fatal flaw
This app works fairly well, but it has one huge flaw that makes it a pain to use: when you follow a link and then want to return to G+, it reloads your full steam all over again. That is slow, annoying, and unwanted. I want to pop out of G+, look at the link material, then return to G+ WHERE I LEFT OFF. Considering that following links is a primary activity when using G+, that is the natural way to go, not the way this app is built.
For comparison, look at the Twitterific app. When you click a link in Twitterific it opens the link in a new page. When youre finished reading you click DONE and you go back to your Twitter stream where you left off. Lots of other apps do it that way too, as it is the natural and user friendly way. Surely the makers of this app could do that too! It would change my rating from 2 to 4 stars.
