There is an existing app for shooting sports called shot coach https://itunes.apple.com/us/app/shot-coach-video-analysis/id605565597?mt=8 but it is lacking in several areas. A great addition to Coach's eye that would be attractive those in the shooting sports would be the ability to track shots, splits, transitions, reloads and other key elements of shooting. This coupled with the ability to use your side by side video would be an extremely valuable tool to the shooting sports. It should not be difficult to add this functionality to your existing framework. It would be beneficial to be able to tag these events based on sound like in the shot coach app that is only available for IOS.
