Ocean Watch vs Tideline

Find your tide. Ocean Watch tracks tides at 3,300+ stations on every US coast, on iPhone, iPad, Mac and Apple Watch. It works offline. • Offline forecasts. Decades of data and the prediction engine are built in, so the tide is there when the signal isn't. • Tidemarks. Set a height so you know when the water will float your dock or expose your beach. • Beauty with insight. Interactive graphs and visualizations that let you feel the flow over time. • Plan ahead. The Almanac lets you travel into the future and pick your window for fishing, sailing, surfing or paddling. • The big picture. The Weeks at a Glance view lets you see the monthly trends as the moon waxes and wanes. • The little picture. Apple Watch, no iPhone needed. Every station on your wrist, with always-on complications. • Widgets. The tide on your Home Screen and everywhere else. • Area Map. See what's here and where you're going. • Share and export. Send the current tide as a picture, or export a week as CSV or PDF. • Your place is special. We've supplied gorgeous local photographs for many areas, and you can add your own. Stations outside the US and Caribbean have limited support.
