■■■ Features of the angler support app “Shiosai S” ■■■

■Tide graph (tide table, tide table, tide time table)
A tide graph that allows you to scroll horizontally and see the past and future flowing forever. An excellent tool that allows you to check the tide name, moonrise, and moonset at the same time. While scrolling, you can also check the tide level in detailed time units. It also has an enlargement function that displays just the tide graph on one screen.

■Weather information
Pinpoint weather information provided every 3 hours from an angler's perspective. Provides precipitation, temperature, wind speed, wind direction, etc. up to 5 days in advance. Very useful when planning a fishing trip. Add points of interest to your favorites and check them every day.

■Wind rose
Check the frequency of wind direction and wind speed for each direction on a graph. Wind is important for fishing. Sometimes strong winds can make it dangerous, and even a little wind can make it impossible to fish. Read the characteristics of the wind that day.

■Weather warning/advisory
When there is a risk of a disaster occurring due to heavy rain or strong winds, an "advisory" is issued, when there is a risk of a serious disaster, a "warning" is issued, and when there is a significant risk of a serious disaster, a "special warning" is issued. ” to call for caution and vigilance. This app provides information announced by region for each point. Think carefully about what is happening now and what will happen in the future before taking action.

■Shiona calendar
I want to go fishing at spring tide. Did you know that there are various ways to write Ushiona? The tide names published in calendars distributed at fishing tackle shops and in newspapers are based on the ``lunar calendar.'' However, there are several methods, such as the MIRC method and the moon phase method. Even on the same day, the tide name may be different depending on the method. I won't explain the differences between each method in detail here, but since spring tides may vary, please understand each method and choose the calendar method that suits you. This app is equipped with a function that allows you to change the method.

□More than 3,000 points
We provide pinpoint information on everything from weather and wind to waves. The number of points will continue to be expanded. In addition, it is equipped with a function that allows you to create original points such as places that are not listed as points or your own secret places.

□Quickly check current location information
It provides a function that quickly provides nearby information from your current location. You can check information as soon as you arrive at a fishing point without having to select each point.

□Design
We pursue a design that is easy to see and operate by displaying each provided information in separate cards. Rather than cramming too much information into one screen, we have adopted a simple design that provides just the right amount of information.

□Customize
It has a customization feature that allows you to change to your favorite color theme. It also has a dark mode. Dark mode is a function that darkens the color base on the screen. It has the feature that your eyes won't get tired even if you keep looking at the screen in a dark place.
