Overall, I have found the iOS Google apps to be very accessible/usable with VoiceOver. For example:
Google+, Snapseed, Photos, Google My Business, Inbox, Chrome, Hangouts, Drive, Docs, Sheets, Search app, Play Books, etc.
It would be great to have a discussion and have input from others:
who have Googlefied their iOS experience and
how you find the VoiceOver accessibility of Google apps works for you?
