FrameCalibur is a free iPhone application developed by Federico Pfeiffer in the Utilities & Tools category. This program allows users to view detailed frame data of characters. Users can select a character to explore its moves, filter, search, and easily sort them. The drag bar feature enables swift navigation between different move categories such as vertical or special attacks.

Moreover, users can select a second character to analyze all moves that can be punished from that character. By clicking on a specific move, users can access all the corresponding punisher moves. FrameCalibur provides a convenient way for players to strategize and understand the nuances of character moves in various scenarios.
