About Racket Theory
Good setup decisions
start with your game.
Built by a tennis-playing designer who wanted a clearer way to connect equipment choices with what happens on court.
Beyond the spec sheet.
Rackets and strings come with plenty of numbers. The harder question is what they mean for the way you actually play.
Racket Theory brings your Player DNA, current setup and match notes together. String Advisor and Racket Finder use that context to help you explore equipment choices.
Your experience stays part of the story.
Save a match, describe what you noticed and return to it later. Trends helps you look for recurring signals across recent logs, while String Life gives you an estimate to help plan restringing.
These readings are starting points to test on court. They don’t guarantee a result or replace your own judgment about how a setup feels.
