Tidal Map app for iPhone and iPad

Tidal Map is an app that visually displays global tidal levels and currents on a map. It can observe changes in tides on a large scale.
In addition, the tide map can also query the tide and current data at any time by location, and provide the high tide and low tide timetable for the coming year.
Note: This APP loads astronomical tide level and tidal current data, excluding the increase or decrease of water and residual current changes due to meteorological or other factors. In special cases, typhoons, cold waves, floods and other factors should also be considered.
