Fish Flingers
This app is also integrated in the Alt1 toolkit.

Fish flingers

This app calculates the quickest possible way to get all tackles at 100%

Guide

First make a screenshot of the overview interface and paste that in the app (or click the Read locations button if you're using Alt1)

Next you can add any hints you and the people around you get from the fisherman by clicking the Enter hints button.

When the game begins just use the shown tackles in the interface at the indicated location. If you're using Alt1 and catch a fish the interface will automatically update to the next fish. Without Alt1 you have to make another screenshot and paste that.
