Inside the Bay
Every component, engineered to fit a single court.
Tennis, engineered for the city. Sensor technology tracks every shot with zero latency. No partner required — just you, a racquet, and up to 1,500 balls an hour.
A typical rally delivers ~300 balls an hour. Rally House delivers up to 1,500 — five times the reps, same session.
Dial in depth, speed, spin, and direction to build custom ball patterns tailored to your game.
Players improve 3–5x faster than on a shared outdoor court, thanks to the reps and instant feedback.
Shot data appears in real time, so you always know what's working and what to adjust.
Practice on your own with guided drills and real-time feedback. No coach, no partner, no waiting — just focused repetition at your own pace.
Master short, cross-court, and full-court rallies for game readiness. Build consistency and court coverage with patterns that mirror real match play.
Design your own drill sequences — set the depth, speed, spin, and direction of every ball. Repeat the exact pattern until it's automatic.
Score points by hitting moving targets. Builds coordination and keeps every session fun and engaging — great for all ages and skill levels.
