How it works
Three steps to a better swing
No sensors. No radar. Just your phone.
Record
Film your swing face-on with any phone. No special setup, no sensors, no tripod required.
Analyze
AI measures 15+ biomechanical metrics against tour benchmarks. Every joint, every frame.
Improve
Get your score, your biggest opportunity, and a specific drill to fix it — in seconds.
Real coaches. Real clubs.
Connected to your club.
ScratchLens partners with golf clubs so you can book lessons directly through the app. Your coach receives your AI analysis before the lesson — zero time wasted on diagnosis.

Research & Science
Built on science, not guesswork
Our scoring engine is grounded in published biomechanics research from the world's leading sports science institutions.
Technical University of Munich
#1 ranked engineering university in Europe. Biomechanics research informing our measurement and scoring models.
Titleist Performance Institute
The TPI Big 12 fault taxonomy. Tour-level benchmark data for every swing metric we measure.
Penn State 3D Biomechanics Lab
Linear motion benchmarks for pelvis and torso displacement at address, top of backswing, and impact.
Stanford · Frontiers in Bioengineering
Peer-reviewed research on 3D swing kinematics across different clubs and skill levels.
Benchmarks sourced from 10+ peer-reviewed publications and professional tour measurement data.
Why I built this
I wanted the best swing analyzer on the market. So I built it.
Julio
Founder & Builder
I develop personal AI systems, and I run an agency that helps businesses grow. I'm not a tour pro — I'm a builder who got obsessed with his own swing and couldn't find a tool that actually measured it.
I'm studying Mechanical Engineering at TU München — ranked #1 in the EU for the field. Scratch Lens is where that training meets the obsession: biomechanics, computer vision, and a score I can trust — the analyzer I wanted in my own pocket.
I stopped waiting for someone else to build it, and built the instrument I wished existed.
