Marine Metrics puts the tide, wind, sun and sea temperature for any stretch of coast on one clean, dark screen. Search any beach, harbour or town, not just the nearest tide gauge, and scrub the chart to see the height at any hour. It's honest about its data: tides are labelled as predictions, and sea temperature is a measured satellite reading. Save your spots and see the next tide in a Home Screen widget. Free for today's tides; Premium adds a 7-day outlook, 20 spots and widgets.
