Quadras
— How it works

Three steps.
Zero hassle.

Whether you have five athletes or fifty, Quadra fits the way you already coach — your courts, your hours, your prices.

1

Set your hours.

Tell Quadra when you teach, on which courts, and at what price. Athletes can only book the slots you've opened.

Athletes book & pay.

They pick a slot in the app, pay PIX or save a card, and the session lands on your agenda — already paid.

You teach. They progress.

Show up, run the session. Athletes track their packages and progress; you see who's behind and who's ready for the next level.

AI Coach · Always on

A coach that never sleeps, in the same app.

Between sessions, your AI Coach answers questions, gives drill ideas, and keeps a journal of how you're feeling on court. It learns from your past sessions and notes — so it actually knows your game.

Ask anything.
"How do I fix my second serve toss?" — drills, video cues, technique tips, on demand.
Journal as you go.
Log how a session felt, what worked, what didn't. The AI builds a picture of your progress over months.
Knows your game.
Pulls context from your real sessions and coach notes — answers are about your tennis, not generic.
Q

My second serve felt loose today. Ideas before tomorrow's match?
Two things from your last 3 sessions: your toss is drifting back, and you're cutting your follow-through short. Try 5 minutes of toss-and-catch tomorrow, no swing — just land it 30cm in front of your front foot. Then 10 serves focusing on a long swing through the ball. Want me to add it as a warm-up reminder?
Yes, ping me at 8am.
Ask your coach…
— Built with coaches
I stopped chasing PIX transfers and writing down sessions on paper. My athletes book themselves, pay before the class, and I just teach.
