That was fast Google!
Approximately a week ago I suggested that Google integrate translation in Google+ within their iOS app (a feature my Android brethren have apparently enjoyed for quite some time).
After the latest Google+ update which included full resolution backup of images & videos (long overdue honesty), Google also integrated their translating feature within Google+.
Tapping on the widget at the top of the screen…
…then tapping on the “Translate post” button…
…will automagically translate the post within the app!
Note: most apps either open up Google Translate via Safari/Chrome or open up the official Google Translate App itself.
Interestingly the post will stay translated even after traversing back to the main stream (but only for awhile).
