How it works
How Caddium works
Film one swing with your phone. The AI analyser measures it at address, top, impact and finish and gives you one focus point with a drill.
How it works
Three steps. No equipment.
- 1You filmOne swing of five to ten seconds with your phone. Your whole body in frame, camera still.
- 2The AI analyser measuresIt finds address, top, impact and finish and measures your swing at those moments.
- 3You get one focus pointShown on your own swing, with one sentence and a drill. This is what it looks like:

The four moments
Address, top, impact and finish.
The AI analyser finds these moments in your video by itself. You don't have to point anything out or trim anything.

- AddressYour setup just before you start.
- TopThe highest point of your backswing.
- ImpactThe moment the club hits the ball.
- FinishHow your swing ends.
What the AI analyser measures
Eight things, at the moments that count.
You see every part back on your own swing. The camera angle decides what we can measure.

Head: sideways
From address to impact your head stays in the same place; you turn around a fixed point.

Head: height
From address to impact your head stays at the same height.

Hips: towards the ball
From address to impact your hips stay on the line behind you.

Posture: spine angle
We measure how far forward your upper body leans at address, top and impact and whether you stay over the ball.

Tempo
With a smooth rhythm the backswing takes about three times as long as the downswing.

Downswing sequence
This is how it should go: hips, then shoulders, then hands. That sequence is where clubhead speed comes from.

Weight shift
Your weight moves to your front foot before or at the start of the downswing.
Keep turning your front hip until after the ball.
Hip turn at impact
Your hips keep turning through the ball. That is how your top speed arrives at the ball.
The difference
Why not a regular chatbot?
A regular chatbot
- Describes what it thinks it sees in a few separate frames.
- Sometimes tells a different story for the same video.
- Gives a list of tips.
- Starts every conversation from scratch.
The AI analyser
- Measures 33 points on your body, frame by frame.
- Measures the same video the same way every time.
- Only mentions what was measured, and that text is checked.
- Picks one focus point, shows it in your own swing and keeps all your analyses in one place.
The swing score
Four parts of 25.
Posture, downswing, tempo and weight shift together make up your swing score.


- Your focus point is marked in your scoreThat is where you gain the most, so that is where you start.
- Nothing guessedWhat your camera angle can't see stays open in the ring instead of being estimated.
- How to fill the ringFilm from the other angle too and the missing parts are measured.
One focus point
One thing to practise.
No list of twenty points. You get the focus point on your own swing, a drill that fits it and a swing thought to take to the range.

Keep your head behind the ball until after impact.
A recording check first
We check your video before we measure.
First we check that your video is usable: its length, the picture quality and whether it holds a full swing with your whole body in frame. If not, you read what to film differently. Your analysis simply stays put for another try.
What we check
- The length of your video
- The picture quality
- Your whole body in frame
- A full swing
Is something wrong?
Then we tell you what to do differently and you can film again straight away.
The loop
Film, practise, film again.
After your practice you film again and see whether your focus point has changed. Your analyses are kept, so you can see your progress.

You already have your phone. The AI analyser does the rest.
