Good morning from Hamburg / Germany

The link from the BSH for the tide prediction in Germany has changed.
Here is the currently working link.

I refer to the website of BSH because it is the most accurate info. I would prefer having the same accuracy in an app. Preferably an app that also is available for my samsung smartwatch.
Cheers
