Your putting stroke, measured.
Prop your phone up, hit five putts, and find out what your stroke actually does — not what it feels like it does.
What the baseline covers
-
Set the phone up
Face on, level with your hands, about two metres away. The app shows you a framing guide.
-
Hit five putts from six feet
One recording, five strokes. Putt as you normally would, not as you think you should.
-
Read what your stroke did
Tempo, stroke length either side of the ball, head and body movement, and how much all of it varied.
-
Work on the three things that matter
You get a short practice session built around your biggest fault. Come back, film it again, and see whether it moved.
What it can and cannot see
A phone camera at 30 or 60 frames a second can time your stroke and measure how far things move. That covers tempo, acceleration through the ball, and how still you stay — which is where most putts are lost.
It cannot measure face angle or path to a fraction of a degree. A putt from six feet misses if the face is one degree open, and no phone resolves that reliably. If you want those numbers you need a launch monitor. Everything here is something the camera can genuinely see.

Reading the clip
Where did they finish?
The camera watched your stroke but has no idea what the ball did. Five taps and it can tell the difference between a stroke fault and an aiming fault.
