Check Your iPhone for 32-Bit Apps That Won’t Work in iOS 11

You know you have 32-bit apps in iOS 10.3 when you open one and get the message: “This app will not work with future versions of iOS. The developer of this app needs to update it to improve its compatibility.”

When iOS 11 is released later this year, it’s widely believed that Apple will remove support for older 32-bit applications. A small, but telling feature from iOS 10.3 seems to confirm this, as the latest firmware now has the ability to detect apps that are still running 32-bit processes on your iPhone, iPad, or iPod touch.

The shift has been a long time coming, with the introduction of the iPhone 5s back in 2014, which used a 64-bit A7 processor. Since then, Apple has warned app developers of its eventual move away from 32-bit architecture, but as many as 187,000 apps still aren’t updated and could soon stop working.

Thankfully, there’s a hidden tool in iOS 10.3 that lets you find all of the 32-bit apps on your device. So before your favorite apps become obsolete, I’ll show you how to see which ones are outdated, and even contact the developer to get them to update their apps to the new 64-bit architecture.

Step 1Check for 32-Bit Applications

iOS 10.3 has made it easy to check for any outdated 32-bit apps. Simply head to the “General” menu in Settings, then tap “About,” and choose “Applications.” A list of outdated apps should now automatically show up to give you notice.

If you can’t tap on “Applications,” and don’t see an arrow next to it, that means you don’t have any 32-bit apps and don’t need to worry about anything right now. Lucky you.

Step 2Contact the Developer

If you have 32-bit apps installed that are really important to you, contact the developer right away to see if there’s an update in the works. To reach out to an app developer, simply go to the offending app’s page on the App Store by tapping on the app name in the 32-bit list, then tap on Developer Website. From there, go to their contacts link and leave them a message.
