Apple is set to launch an app called “Move to iOS” that will make it easier for Android users to migrate to iOS.
Move to iOS is one of the newest features introduced with iOS 9. According to Apple’s website, the app “securely transfers your contacts, message history, camera photos and videos, web bookmarks, mail accounts, calendars, wallpaper, and DRM-free songs and books.”
As for apps installed on your Android phone, Move to iOS will look for its iOS counterpart and will be suggested for download from the App Store. Paid apps will be added to your iTunes Wish List.
