I've been testing some features of tenniscutapp and this is the selling point for me! But it actually does so much more... I've provided a little feedback on it and hope to see that implemented in a future update coming soon. That said, the feature is both interesting and helpful! You get a clear path of the ball and can learn how spin affects trajectory. Tip: film from a high up angle! App might struggle to track ball reliably otherwise. I mounted from top of fence for this shot and it seems to be about 90% effective and with perfect accuracy while it's actually tracking.
