I use and app called Fishing Deluxe for the calendar, they have added weather also in the past year, and you can also log the days you fish with whatever info you want to add. It also has 1 button to push and it adds the weather at the time you are fishing. I really liked it when they added that. It also had a map that you can place spots that you want to save. I also have Weatherbug, its also pretty simple and easy to use.
