Schedule, heights and coefficients of the tides on more than 150 French ports and some ports in Great Britain.

Application made from the harmonic constants provided by Previ Mer.

It is completely autonomous: the internet connection is only used for updates and for displaying maps.

No advertising. No use of geolocation data outside the application and only to locate the nearest port.

All local times displayed are summer and winter times.

The menu allows you to calculate the tides and give the specifics for a day

Set your own threshold (minimum height for practicing navigation or maximum for fishing on foot).

Ask for other ports if necessary.

Thank you for sharing your comments in order to further improve the application.
