Thanks for the feedback, I'll rewrite the description in the next update. While keeping score yourself on the Watch isn't ideal (having someone else do it, say your friend on your paired iPhone is) I figured the 5 seconds or so after a point is enough for someone to tap the top half of their Watch screen or the bottom half without it interrupting the flow of the game.The description needs to be improved. Why should I use this app. Tennis is one of the easiest games to score, and I don't want to be going to my watch between every point. What's the purpose for the app? What problem does it solve? You description answers none of those questions.
