For parents of junior golfers

Your child's swing.
Not Tiger's. Not Rory's.
Theirs.

SwingSet uses your child's actual body measurements to calculate their ideal stance, knee flex, spine angle, and distance-to-ball. No camera. No adult templates. Just a tape measure and biomechanics.

The problem

Every junior golf app compares your child to an adult.

Video analysis has error margins

Computer vision breaks down outdoors, on uneven terrain, and with non-standard camera angles. The data you get is wrong more often than it's right.

Adult templates fail growing bodies

A 9-year-old's torso-to-leg ratio changes every few months during growth spurts. Forcing a static adult template means practice built on a faulty foundation.

Injury risk from poor fundamentals

Teaching a child to swing like an adult creates compensations that load stress on joints, growth plates, and tendons that aren't designed for adult-level forces.

How it works

Three steps. Zero cameras. Real biomechanics.

01

Measure your golfer

Our guided wizard walks you through 5 measurements: height, arm span, torso length, leg length, and shoulder width. Looping animations show you exactly where to place the tape on each body landmark.

02

Our engine calculates their setup

Using peer-reviewed biomechanical relationships, SwingSet converts your child's proportions into their personal stance width, distance to ball, spine angle, and knee flex — exactly what a pro would calculate in a lab.

03

Re-check every 3 months

Kids grow fast. SwingSet tracks your child's history and alerts you when it's time to re-measure after a growth spurt. Your setup stays accurate as they develop.

Height
Arm span
Torso
Leg
Shoulder
These 5 numbers define your child's unique setup.
Body proportions

Every child's ratios are different. Yours should match yours.

Two kids who are the same height can have completely different arm spans, torso lengths, and leg ratios. That's why a standard template always misses the mark. SwingSet builds the setup from their proportions, not a population average.

Arm span to height ratio

Determines ideal shoulder rotation and backswing plane

Torso to leg ratio

Drives spine angle at address and ground force mechanics

Shoulder width to hip ratio

Defines balance center and weight distribution

Growth Alert

3 months since last measurement. Time to re-check.

James's arm span has grown 1.4" since February. His original stance width is now 6% too narrow for his current proportions. Re-measuring takes 3 minutes — and keeps his practice precise.

Multi-child profiles

Manage measurements for every junior golfer in the family from one account.

3-month re-check reminders

Automatic alerts after growth spurts so you never practice on outdated numbers.

The science

Built on the same principles used by elite junior programs.

SwingSet's calculation engine draws from peer-reviewed biomechanical research and the same body-proportion analysis methods used by national golf federations and sports science institutes worldwide.

I

TPI-influenced methodology

Body-swing connection principles aligned with the Titleist Performance Institute framework used by coaches worldwide.

II

Kinematic sequence research

Proper sequencing from ground up: how weight transfer, hip rotation, and torso coil connect to individual body ratios.

III

Growth-safe training load

Calculations designed to keep force outputs within safe ranges for developing growth plates and joints.

SwingSet does not replace a qualified golf coach. It gives your coach an accurate starting point — and keeps it accurate as your child grows.

Built for
their body

The only setup your child needs is theirs.

Stop borrowing adult templates. Start with your kid's actual measurements, calculate what their body actually needs, and build a swing that grows with them — not against them.
