A free app for Android, by c.guine.
The tide application provides the most accurate tide times, heights, and tidal coefficients for 150+ French ports and a few British ports.
The application is completely free and has no ads or other ways to get money. It is made from the data provided by the port authorities and is updated every time a new data is available.
The application can also calculate the height of the water, in order to calculate the best time to get the required amount of fish or to catch the required amount of water.
It is possible to choose the period for which the data is provided, in order to get the time for a specific day or a specific month.
