Is MTR tracked per account or per project?

We currently have a single Project on our Account but plan to add a second, in order to have separate apps with separate subscriptions.

I have seen a post which says that MTR is tracked at an Account level, not per app, but I’m not sure how Projects fit in.

We will have one Account, with two Projects.

Each of those Projects will have two Apps (one iOS, one Android).

Is MTR tracked at an Account level or a Project level?
