An App Clip is a small part of an app that lets you do a task quickly, like rent a bike, pay for parking, or order food. You can discover App Clips in Safari, Maps, and Messages, or in the real world through QR codes and App Clip Codes—unique markers that take you to specific App Clips.
With some App Clips, you can tap the banner at the top of the screen to see the full app.
