What happens to 32-bit apps on a device after an iOS 11 update?

I have several dozen 32-bit apps on my iPhone. What happens to them after I update the device to iOS 11?

Is there any way to save these 32-bit apps off of the device? (for use with a spare iPhone 5, for instance)


The data and application are both left intact. If you try to tap on those apps, it takes you to the settings / App Store to contact the developer and explaining the app will not run.

You can pre check on iOS 10 in the settings app.
