It predicts the tides of about 340 places in Japan and displays them in a graph.
The Tide Graph is calculated using the tidal anharmonic constant in the app, so it can be used even in places where the network is not connected.
Even if the year changes, data updates such as updates are not required.

Today's tide graph flickers the current time, so you can see the current and future tide movements at a glance.
The sunrise and sunset are also calculated and displayed graphically, which is convenient for early morning surfers and anglers.

Since the location displayed once is automatically saved as history, it can be easily called from the menu.
You can also use the GPS function to search for and display the tide graph closest to your current location.

At the end of January 2021, weather information provision and widget functions have been removed.
