Abstract: Embodiments of the present invention are generally directed to devices, methods and instructions encoded on computer readable media for capturing motion and analyzing the captured motion at a portable computing device. In one exemplary embodiment, a motion capture and analysis application is provided. The application, when executed on a portable computing device, is configured to capture video of a subject (i.e., person) while the subject performs a selected action. The motion capture and analysis application provides various tools that allow an application user (e.g., trainer) to evaluate the motion of the subject during performance of the action.
