With SketchUp Viewer you can store and share 3D models on your iOS or Android mobile device. SketchUp Viewer is a great way to share models with clients or have a portfolio of 3D models on hand when you're on the go. The SketchUp Viewer for Mobile app also offers AR model viewing capabilities for users with an ARKit (iOS) or ARCore (Android) enabled device. See Viewing Your Models in Augmented Reality for more info.
To view your own models in AR, you will need an active SketchUp Go, SketchUp Pro, or SketchUp Studio subscription. For more information on these subscription plans see Plans and Pricing.
