Don't need an app, look at the pastures. When the cows are laying down the fish won't bite. Does the same apply to hunting? I don't have a clue but I'm sure hunting pressure has a lot to do with movement too.
CAUGHT MANY A FISH IN FARM PONDS AND ON LAY WHEN THE COWS A LAYING DOWN.. KILLED MANY A DEER IN PASTURES WHEN THEY ARE LAYING DOWN AS WELL
