Why don't any Google apps work on my iPhone?

I have google drive and Google books on my iPhone but non of them seem to work?
I have been trying to log into my account using 3G but as soon as I tap 'add account' it comes up saying network unavailable, I've made sure my 3G is getting to this app so why won't it work? Why dont any Google apps work on my iPhone - 1

Because Apple locks out android features.

Their hardware is completely different so you need to use appstore instead.

  • Will moving photos/videos from iPhone to google pictures in google drive free space? Just wondering if moving all my photos into the google pictures (photos?) section of the google drive app on my phone will clear up memory space?
  • Why won't iTunes transfer any song or any file to any of my devices? I have unistalled and reinstalled iTunes multiple times. When I go to to transfer a song to iphone, ipad, ipod it just freezes up and doesn't do anything. I'm running the newest version of the program. What do I need to do? Just want to fix it. Thanks. I have waited on the program to transfer just to see if it is slow or what and it took 30 mins and nothing. I can't download software updates also.
  • Why won't any of the apps on my iPhone work? I tap an app and it just… Does nothing. I tap other apps like iMessage, Instagram, Facebook, mail, and nothing happens. Even when I press the lock button, nothing happens. What can I do? Also, it's an iPhone 5 and it's not jailbroken or anything like that.
  • Why don't iPhone users just download google hangouts? Instead of Facetime? Works just like Facetime but you can video call anyone on any device. And you can have up to 15 people on a video call, and message and screenshare. Facetime can't do any of that. But iPhone users rather everyone buy a iPhone just to facetime when they can use hangouts and video call the same.
