I show you the steps to creating a unity augmented reality app that can be put on your iphone or ipad. You'll need:
A vuforia account: https://developer.vuforia.com/
A Apple Developer license: https://developer.apple.com/programs/
A free version of unity: https://store.unity.com/
A 3D program if you want to create your own models. I personally use Cinema 4D
Final app in action: • Augmented Reality Vuforia Unity
