The PrimeTimes system, found in four different calendars and explained in its popular book, How to Know When to Go, has been the gold standard of when to go fishing and hunting since 1986.  And its Ultimate PrimeTimes software has been number-one since 2001.  Now as an app, Ultimate PrimeTimes truly is the ultimate in forecasting fish and game activity, as it adjusts to your exact location via GPS.  You also get 23 choices of what you are going after, from bass, walleyes, and offshore…to deer, waterfowl and coyotes. It even fine-tunes to your current fishing conditions, including today's weather and water conditions!  This interactive forecaster is loaded with features and very easy to use. Its data goes back as far as 2005, so you can check its predictions against past outings.
 
You can try it free with limited features and ads, buy it for only $9.99 a year with no ads and all features, or use it monthly for only $0.99 per month.  Whichever option you choose, you can run it on the internet AND your smartphone, which makes Ultimate PrimeTimes available to virtually everyone.
