HarborTide: Tides & Currents

Live and offline tide & current forecasts for 12,000+ stations worldwide - with Home & Lock Screen widgets, tide alerts, sun & moon times, and nearby-station sorting.

HarborTide gives you clear, reliable tide and current forecasts wherever the water takes you and keeps working when your signal doesn't.

Browse a built-in catalog of more than 12,000 tide and current stations around the world. Live predictions come from official sources: NOAA CO-OPS for U.S. tides and currents, the Canadian Hydrographic Service for Canada, plus global coverage through national providers and tide-forecast.com. Once you've viewed or saved a station, its predictions are cached on your device, so HarborTide keeps working in airplane mode, out at sea, or anywhere off the grid.
