What coaches are saying
SwimAnalyzer helped me understand in seconds what was truly limiting my swimmers' progress. An indispensable tool.
Marie L.
Île-de-France Swimming Club
The precision of the race models is remarkable. I can finally show my swimmers exactly where their gaps are relative to elite benchmarks.
Thomas R.
France National Swimming Centre
In 25 years of coaching, I had never had such a complete tool for individualizing each swimmer's work. It's a true paradigm shift.

SwimAnalyzer was built with a simple intention: to turn swimming data into information that is genuinely useful for progression.
A fascination with technique, movement, and the efficiency of gesture — present since childhood — gradually gave rise to SwimAnalyzer.
The project is now built on over 25 years of swimming coaching experience, 15 years of race analysis, and an approach centered on understanding performance.
Over the years, I had the privilege of accompanying swimmers to the 2016 Rio Olympic Games and the 2018 Buenos Aires Youth Olympic Games, and of collaborating with some of the most respected coaches in the world, including Fabrice Pellerin and Guennadi Touretski. These experiences deeply reinforced my conviction that performance never rests on a single factor, but on complex balances that must be learned, understood, and analyzed.
My training as an osteopath also allowed me to develop a sharper reading of neuromuscular mechanisms, coordination, and biomechanical constraints that influence movement efficiency. This approach progressively strengthened my belief that performance is built through complex balances — often invisible, yet essential.
I discovered that behind every performance lie measurable and identifiable patterns, as well as intricate balances between coordination, motor efficiency, and the swimmer's capacity for adaptation.
"Every metric, zone, and indicator in SwimAnalyzer was designed with the requirement of offering tools that are genuinely usable in the field — in service of understanding, progression, and lasting performance."
