eTide HDF is the most accurate tidal app available. It provides not only information about current and forecast tides but also the depth at the desired location in feet, meters and kilometers.

You can set either standard time (local, telephone, and GMT), use one of the automatic time-zone detection methods, or choose the one you prefer most. If you are going to use the tide chart for the voyage, you will need to turn off automatic time zone detection in order to make sure that you know your precise time zone.

You can see not only the data of your desired location but also the data for over 10,000 tidal stations worldwide. You can also add these data to your watchlist.

For each station, you can change the data format from a range to a table or graph. You can see the whole data for the current and forecast tide in a table or graph. You can see a single station's data as a table or graph.
