UWPSpy is a handy and efficient tool (brought to you by the developer of Textify and 7+ Taskbar Tweaker) that caters to the needs of UWP app developers. It offers practical and convenient features that allow developers to view real-time changes in their projects instantly. With UWPSpy, developers can quickly and seamlessly optimize the development process, leading to a more streamlined and effective workflow.

Modify UWP apps
With UWPSpy, you can modify UWP apps by repositioning UI elements and more. Whether you want to make minor or extensive modifications, you must have some knowledge in this area to manipulate the apps effectively. Fortunately, UWPSpy streamlines the process and minimizes concerns, making it as smooth as possible.

Observe changes in real-time
UWPSpy enables users to observe how changes affect the structure and functionality of their UWP app. It's beneficial for helping with UI design tasks during app development. When you select specific properties, the linked elements will be highlighted, and any changes will update in real time.

Usage:

Run UWPSpy.exe and select the UWP/WinUI 3 application you want to spy on.

A window with the application’s UI elements will appear for each UI thread of the target application.

A UWPSpy spying window can be closed, in which case it will become hidden. It can be shown again by running UWPSpy.exe again and selecting the same application.

To completely stop spying on an application, its process must be terminated.

It is always a good idea to have a restore point just in case you run into a problem.
