I Want to Track X-Z Phone Position. Should I use VR?

Hi there!

We're working on an app where the user will need to catch a projectile in flight, and we thought it would be cool to use the physical position of the phone to move their hand to catch the ball. I know that AR/VR frameworks have this capability since they use it to track camera position. However, I wonder if there isn't a simpler way to do this since all I need is to track the X-Z position of the phone without considering rotation or real-world objects. Any ideas on a simpler way?
