App Design Viewer

App Design Viewer is the powerful companion app for App Design Studio on iOS and macOS that allows designers to collaborate on their designs, even if they are not in the same location.
With App Design Viewer you can view, prototype, save and comment on your designs. All of your designs that you create using App Design Studio are automatically synced to App Design Viewer and kept up to date using iCloud. You can also view any projects that have been shared with you. Any changes made to the designs in App Design Studio are updated live on the screen without having to refresh the app.

All of the UI objects in your designs are created with code instead of representing them using images. This ensures that the objects are up to date with the latest iOS style and will not lose quality as they are resized. The objects in your designs are positioned and sized using percentage values, ensuring they scale to look correct on whatever device you are viewing them on. You can also render and export your designs as PNG images with a single tap and save them to the Photo Library on your device.

The built in comments allow you to take notes or discuss the designs with your designer. You can also use the prototyping features from App Design Studio to see how your app will behave by transitioning to another view within the project, when pressing on certain parts of your design.
