How to find out which of your apps are not compatible with iOS 11

Last week saw the release of iOS 10.3, and thoughts are already turning to the next major release of Apple's mobile operating system. When iOS 11 launches later this year, it is not expected to support 32-bit apps and this means that a number of apps that have not been updated accordingly will stop working.

Built into iOS 10.3 is a tool that can be used to quickly determine which of your apps could die in iOS 11. While it's possible that updates might be released for them, Apple's move away from 32-bit software is far from new, so it's probably time to start looking for 64-bit alternatives for anything you have come to rely on.

As we have noted before, Apple has not permitted apps that do not support 64-bit mode to be submitted to the App Store since the start of 2015, so if you have any apps that are still awaiting updates after two years, you can probably kiss goodbye to them. But how can you tell which of your apps are going to be affected?

Assuming you have updated to iOS 10.3, head to Settings > General > About > Applications. Here you'll see a list head: "These apps may slow down your iPhone and will not work with future version of iOS if they are not updated. If no update is available, contact the app developer for more information."

Up until now, Apple has only warned that 32-bit apps could slow down devices, but now the warning is more severe. While there has been no official announcement about exactly when 32-bit app support will completely end, it is widely expected to be in iOS 11, although the iOS 10.3.2 update is also a possibility.
