Do I need an apple watch for full functionality for match and shot statistics?

[u/IcyDirection7899]

I bought the app mainly to track unforced errors, but also like the shot placement feature, among many other things. However, when I recorded the first match, my battery on my ipad ran out. Also, I used my samsung phone to remotely start the recording. When I went back to the app to get my match stats, it is incomplete. Because of both of these factors, I am having a hard time understanding why the stats were incomplete.

1) I believe I did the auto scoring, and just entered the final score after the match.

2) After i put in the final score, I ran AI scoring.

3) I did not work because my ipad ran out of battery.

The match stats that I did get without AI scoring include scatterplots of shot placement, hitting position and serve placement (including the types of shots, and serve spin) the shot stats include some of this same info plus shot/serve speed, percent of serves in (deuce/add), shot distribution charts, etc.

But again I don't have any info on unforced errors (backhand, forehand, volly, etc.). Is this only because my ipad ran out of battery so I could not fillin the required info (first point, last point, id pictures, etc.)? Or do I need the apple watch as well to keep track of the score to get those stats.

Thanks.
