This is the problem I think. Their web app (both for Gmail and G+) are very good, so people expect that an iOS app for the same product will also be very good.

Then they went and released the iOS app for G+ and it was woeful (and continues to be woeful after a couple of updates). I didn't get the new gmail app before they pulled it so I can only speculate (and considering they pulled it rather than left it to iterate, I'll assume the bugginess was pretty bad).

Why is it they can get a mobile web version of an app so right and get the same native app so wrong?
