Prott Viewer is a free Android app from Goodpatch Inc. designed to provide a seamless viewing experience for all prototypes designed with Prott. Its simple interface allows you to focus on previewing the prototype in all its interactive glory. All you need to do is download the app, tap on the preview URL or scan the QR code, and hit play to start viewing.

One of the best features of this app is that it allows you to view prototypes offline after they have been stored in the app. This means you can have easy access to them anytime and anywhere. Additionally, if the comment feature has been enabled on the prototype, you can share your thoughts from within the app by tapping the comment icon.

Overall, Prott Viewer is an excellent tool for anyone who works with Prott prototypes. If you have any questions or feedback, the Prott team is always available to help.
