Mr. Tides 2.0.5 is a maintenance update to the open-source application that provides tide and current predictions in a wide variety of formats (graphs, text listings, and calendars or a tide clock). It uses the algorithm used by the National Ocean Service in the U.S., which "is significantly more accurate than the simple tide clocks that can be bought in novelty stores." [Classic, OSX]
