My website is a forum. The native mobile app's only function is to access the forum and provide a better experience than can be provided through the browser.

Given that the same content is being accessed, should I use the same Google Analytics tracking code?

Or should I create a new property and select "Not a website" when it asks for the website?

I was not able to find anything that discussed this and what would be best practice, given that the same content is being accessed.

Thanks!
