Moonwater
Tides for your location
Free · Designed for iPad. Not verified for macOS.
Know the tide at a glance — your location’s high and low water in a clean, beautiful chart.
Moonwater shows the tide for your current location the moment you open it, in a smooth, beautiful chart.
• Automatic location, or search any coastal place in the world
• Scrollable sea-level chart with the current height, the next high and low water, and whether the tide is rising or falling
• Scrub through the chart to read the height at any moment
• Home-screen widget for your last viewed location
• Available in Dutch, English, German, and French
Tide and sea-level data come from Open-Meteo (MeteoFrance SMOC model).
Note: Moonwater is for general information only and is not suitable for navigation. It does not replace an official tide table or nautical almanac.

A big update for iOS 27:
• Tide briefing for runners and surfers: see when the sand is firm or how good the waves are, with personal advice on devices with Apple Intelligence.
• Sessions on the Lock Screen and in the Dynamic Island: count down to firm sand or the next tide.
• New large widgets, including iOS 27's extra-large portrait size.
• Ask Siri "When is low tide in Moonwater?" and find your favorites in Spotlight.
• Drag favorites into your own order.
• More accurate high and low tides: a double low water now shows its lowest point.
Moonwater now requires iOS 27.
