If you have an Android device with the latest OS system installed, you will know the expression “OK Google” as it can be used to launch Google Now. 
It's a very smart feature compared to other systems like Siri, where you have to press and hold the home button.
So if you have an iOS device you will probably miss the "OK Google" feature.
Google has released recently an updated one version of the iOS app, which brings the feature in question to all users of Apple's operating system. With the updated app, users can say “OK Google” anywhere within the app and the personal assistant will be activated.
However, it works only through the application, which means that if Google App is closed, then it obviously will not work.
Agree, it's not that easy to integrate across the system, but we agree that Google's developers are close enough, especially if you're a regular user of Google's app.
Alternatively, if you prefer this type of integration system, Siri has an integrated function that works the same way. However, you need to have your iOS device connected to a charger.
In addition to adding "OK Google", there are significant changes to the app's update, which gives you more detailed results in local searches and the ability to copy and paste anywhere in the app.
Let's see, will Google developers be able to give iOS the functionality that has the OK Google feature on Android devices? or to put it another way: Will Apple leave them?
