About The Author & This Site
Learn about our mission to provide gamers with free, simple, and accurate tools to master their aim without the clutter of other sites.
Alex Chen is a former semi-professional FPS player with over 15 years of experience in competitive titles ranging from Counter-Strike 1.6 to Valorant. With a background in data analysis, Alex became obsessed with the science of aiming mechanics and the data behind player performance.
He created the Boat Eye Sens Calculator suite to demystify sensitivity and provide the tools he wished he had when starting his competitive journey. His expertise lies in breaking down complex aiming concepts into easy-to-understand guides and tools for players of all skill levels.
