iOS Users, do you use Google apps on your phone/tablets?

Simple question. Personally, I used to all the time, but since Mavericks, I've already switced from Chrome to Safari (on both phone and mac), Hangouts to iMessage.

Still debating on ditching Google Contacts and Calendar for iCloud, but that might never happen (Contacts and Calendar go hand in hand with Gmail, and I would never leave Gmail for iCloud mail). Also still debating on switching from Google Maps to Apple Maps, but that's unlikely too...

How's about yous?
