All 26 charts are available offline. The charts show both direction and rate of tidal streams at hourly intervals by careful and accurate use of graded arrows and display mean neap and spring tidal rates in tenths of a knot. The app also shows you today's tides at Dover, for which an internet connection is required.
This app is universally available on both your iPhone and iPad. The sea maps are zoomable, thus also of good use on the smaller phone screen.
