Three months ago at Google IO they unveiled the new Google assistant for iOS available to the USA, the announcement was a big deal and the assistant was actually able to do some things better than Siri itself. 

Today Germany, France, and the United Kingdom have finally been included in the rollout. The app is 137 megabytes in size and requires iOS 9.1 or later. Unfortunately even with iOS 11 beta it seems as though the Google assistant can still toggle more settings than Siri.
