Setup guide

Set up your iPhone launch monitor in five steps.

Repeatable camera geometry matters more than clever software. Use the same 41-inch overhead position, stable support, centered ball, and even lighting every time.

Quick setup

  1. Mount the iPhone

    Secure the iPhone on a stable tripod with the camera directly above the ball at the guided height of 41 inches.

  2. Center the ball

    Move the tripod or ball until the ball sits in the on-screen target. Do not hand-hold the phone.

  3. Check the scene

    Use even lighting and a background that contrasts clearly with the ball. Remove fast-moving objects from the capture area.

  4. Wait for Ready

    Let True Carry finish its camera and exposure checks. Swing only after the app shows the Ready state.

  5. Keep sessions consistent

    For comparable numbers, keep the same phone, height, ball position, lighting, and ball type throughout the session.

Why placement changes the estimate

True Carry converts movement in camera frames into shot inputs. If the camera height, angle, or ball position changes, the geometry changes too. A stable, repeatable setup gives the model a more consistent view of the launch.

Troubleshooting a missed shot

  • Confirm the app showed Ready before the swing.
  • Increase light without placing a bright glare on the ball.
  • Use a clean ball that contrasts with the mat or ground.
  • Check that the tripod did not move after calibration.
  • Confirm the full launch area remains inside the on-screen guide.

Different setup for swing video

The 41-inch overhead placement is for launch-monitor capture. Down-the-line swing video uses a separate position, roughly six feet behind the golfer at hand height. Do not use the swing-video position for launch measurements.
