About this app

S19Labs turns your booth session into coaching you can actually use — after you leave the range.

Every shot you hit at an S19 booth is captured on radar and filmed from two angles, and your coach marks it up on their iPad. S19Labs brings all of that to your phone, so the lesson doesn't end when the session does.

Watch the coaching film
Down-the-line and face-on, played back at the exact frames your coach flagged — with their voice notes on what's working and what to work on.

See why the ball did that
Carry, ball speed, spin, launch, face and path — the cause-and-result numbers behind every strike, rated so you know which shots to learn from.

Track real progress
Ratings and key metrics trend over time and per club, with your personal bests and the shots that set them.

Keep a private journal
Voice or text notes on how a session felt — stored only on your device.

Book your next session
Reserve your next hit right from the app.

S19Labs is the player companion to the S19 / Studio19 coaching system. You can create your own account in the app, or sign in with one set up by your coach or booth.
