If I were to build an app for improving the performance of a wrestler I would want it to be free, have many video analysis tools, unlimited storage and a stat tracker. I have already downloaded UberSense which is free and has some features like slow motion and tools for comparing technique. I'd like to blend this with Hudl that has unlimited storage and the ability to make highlight videos to share but is not free. All of these features allow a wrestler to see the technique they are performing and get the feedback they need to clear up their mistakes. On the tactics side I would want to include a stat tracker for each wrestler. Points scored for or against the wrestler as well as what type of scoring and when and where it took place on the mat during the match. A wrestler could use this information to better understand themselves, learn to play to their strengths as well as cover any weakness, gradually improving performance.
