The problem

Most tennis apps teach mechanics. The hard part is decision-making under pressure — when to flatten, when to slice, when to come in. That's the part coaches charge $200/hour for, and the part most players never train.

Why now

I played club tennis for a decade. The plateau wasn't power — it was reads. DropVolley is the trainer I wished I had: scenarios every morning, a quiz that catches your blind spots, and a plan that ties mind and body.

Why I'm building this

I built DropVolley because the gap between 'knows how to hit a forehand' and 'knows which forehand to hit' is the entire game above 4.0. Watching highlight reels doesn't move the needle. DropVolley is the system for the player who's done with content and ready to train the part that matters.
