About FighterCenter
FighterCenter is a study workspace for fighting game players. It combines notes, combo collections, drills, frame data, quizzes, and a task list so players can save what they learn, plan practice, and track progress over time. According to the homepage, frame data, combos, and notes cover more than 50 fighting games.
The homepage also describes beginner guides for each supported game, explaining the screen, controls, and terms, and per-character frame data and hitboxes. Players can add combo sets to a personal library and turn saved combos into practice sessions with reps and progress tracking. The homepage mentions iOS and Android options alongside the web app and a Pro option, but it does not list pricing details or describe what Pro includes.
