Automatic update is a great feature
which Apple introduced on iOS 7. When turning on automatic app updates, it
automatically updates to the new version of any apps when connected to Wifi and
cellular data. This is great for most users to stay up-to-date without manually
doing anything. 

Here’s a simple steps on How to disable automatic app updates and downloads on iPhone/iPad running iOS 10.3.2/10.3.1 or below.

But some users like to stay to the previous version and always
want to disable automatic downloading app updates on iPhone/iPad due to some
reason. Because you can’t downgrade back to previous version once you have
updated the app. So doing this you always have an option to stay in the older
version or can update to the latest version anytime you like.
