About
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.
Set tide alerts for upcoming highs, lows, or a water height you choose, and get notified even when the app is closed. Plan your day with sunrise, sunset, and moon phase, check station weather where sensors exist, and glance at Home & Lock Screen widgets that show the current level and the next tide.
Private by design: no account, no ads, no tracking. Your favorites and settings stay on your device, and your location is never transmitted.
