DeerDays is a Deer Movement Predictor, hunting logger/analyzer, harvest logger, photo manager, and a calendar all in one! Hunt on days that you have the best chance of seeing deer, record details of your hunts so that your data produces the best location for the current conditions to hunt, manage every aspect of your herd, and keep your day to day schedule on the calendar. We offer FREE software that you can download and use but you won't have full functionality. Purchase the software for only $10 and you get FULL functionality of this VERY powerful software. When you buy the software you get the following: The DeerDays Calculator which tells you the best days to hunt deer on, the Deer Days Analyzer to find correlations based off of your collected hunting data, and the Deer Days Trend Analysis to show you any trends in your past hunting data. http://www.deerdays.com/
