ultiTide is an iPhone App which provides tide and tidal current predictions for over 4000 locations in the United States and U.S. Territories without the need for an internet connection. A network connection is only required to display the map data in the Local Stations view.

MultiTide is designed to help you plan for anything from a trip to your local tidal pool to a multiday kayaking trip. Change the prediction start date to see future (or past) tide predictions. The three station tabs allow you to easily switch between predictions for up to three different stations.
