iPhones and iPads will no longer run 32-bit apps with the release of iOS 11 later in 2017. Those apps currently display a message saying they “need to be updated”, and they won’t run at all once you’ve upgraded. Here’s how to check which apps you have installed will stop functioning, if any.
How to Check for 32-Bit Apps
When you first launch one of these older 32-bit apps on a modern iPhone or iPad, you’ll be warned. On iOS 10.3, the warning says that “[App Name] Needs to Be Updated” and explains “This app will not work with iOS 11. The developer of this app needs to update it to improve its compatibility.”
This warning began back in iOS 9, released in 2015, where the warning was a more mild “[App Name] Mya Slow Down Your iPhone or iPad” and explained “The developer of this app needs to update it to improve its compatibility.”

This screen lists apps that are 32-bit only and won’t run on iOS 11. If you don’t see any apps here, you’re good—all your installed apps will continue functioning after the upgrade to iOS 11.

This change has been a long time coming. Apple announced that 32-bit apps would no longer be supported in the future to developers back in 2013, four years ago. Starting in 2015, 64-bit support became mandatory for both new apps added to the App Store and updates to existing apps. App developers have had years to prepare for this moment.
That means apps that show as incompatible haven’t been updated in years. Apple would like to entirely drop 32-bit support so iPhone…
