For many simple, yet useful NFC features an app is not required to read NFC tags and perform actions with iPhones that support Background NFC Tag Reading. The native iOS apps such as Safari, Mail, Messaging, Maps and others listen for the appropriately formatted NFC chips and respond with expected actions. The most common being listening for an NDEF website record and opening the URL in the Safari web browser. Not having to download an app broadens the user base that will use the NFC tags as it removes an additional hurdle. As of iOS 15, there is not a dedicated native iPhone app to read NFC tags, and there probably will never be one.
