The Made in app detects where a product has been manufactured. It supports many countries and has the advantage of being able to detect even if the product has been modified or if the manufacturer has changed. 

It is free and has a simple and intuitive interface.

To use the app, first open the app. Then push the button and enter the code you receive on the screen. The application will detect the country of manufacture and will provide you with information about it.

You can also view the world map to get an idea of where the product has been manufactured.
