You can’t install apps onto an iPhone from iTunes anymore. Apple removed app management from iTunes in newer versions. To get apps on your iPhone, open the App Store on the device, search for the app, and tap Get or the download button. If you previously downloaded apps with the same Apple ID, you can find them under App Store > your profile > Purchased. If you’re using an older version of iTunes that still supports apps, you may be able to sync them through iTunes, but for most users today, the App Store is the way to go.
