Fish Cal Lt
This is a good app that gives the expected peaks and valleys of good/bad fishing times and days. I was a little confused with the use of it at first but now it has started to make much more sense. Of course the sun and the moon are important but so is the meteorology of the moment so using this sort of software also requires some buildup of experience by the user to know when fishing will be optimum. Nice though!
