This app has a lot of potential and will impress any fellow hunters at base camp, when combined with a second IOS device with the remote feature. However, in order to get the most benefits from this app, the remote device must be equipped with a set of battery-powered speakers that are loud and clear enough to get the attention of deers. Moose calls should be added for a more complete hunting app. Some sounds should be improved like the rattling and wheeze. The contextual description should either be removed or put on a separate button because users tend to trigger on it instead of on the stop/play which can be bad if you intended to stop a call and it went on the description instead. Finally, the contextual description should be tailored to each call and explain in which situation you should do a sound over another, instead of just talking about the animal itself.
