When opening a 32-bit app in iOS 10.3 beta, users are warned that "This app will not work with future versions of iOS. The developer of this app needs to update it to improve its compatibility."
The warning has led many developers to believe that Apple will drop support for 32-bit apps with the release of iOS 11.
Looking at app intelligence data, Sensor Tower says this could affect about 187,000 apps.
Analysis of currently active apps that have ranked in either the top free, paid, or grossing charts at some point since their release shows that this number stands at approximately 187,000 or about 8 percent of the roughly 2.4 million apps on the App Store worldwide.
Check out the chart below for a breakdown of how many apps could be affected in each App Store category. If you have a favorite app that is still 32-bit, you may want to encourage its developer to update!
