HarborTide: Tides & Currents

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. FEATURES • 12,000+ stations worldwide — tides and tidal currents, searchable and browsable on a map. • Live + offline — predictions are cached automatically and stay available with no connection. • Tide alerts — get notified before upcoming high and low tides, or when the water crosses a height you choose. Delivered by iOS even if the app is closed. • Home & Lock Screen widgets — current level, the next tide, and a sparkline at a glance. • Nearby — sort stations by distance using your location (used only on your device). • Sun & moon — sunrise, sunset, and moon phase for planning your day on the water. • Weather at NOAA stations — air and water temperature, wind, and pressure where sensors are available. • Favorites & recents, imperial or metric units, and a dark, marine-inspired design built for iPhone and iPad. PRIVATE BY DESIGN No account. No ads. No tracking. No analytics. Your favorites and settings stay on your device, and your location is never transmitted. Please note: HarborTide is provided for planning and reference only. Do not rely on it for navigation or safety-of-life decisions. Always consult official tide tables, charts, and local Notices to Mariners.
