What should be app URL vs organisation URL?

I have created an App. Let's say MyApp.

Now, what should be URL for the app?

The name of the organization is also the same. Let's say "myapp Inc".

So what is the best practice to display organization info and app to put into URL?

To be more clear, should app URL be like:
app.myapp.com

and organization URL be like:
www.myapp.com
