Low Tide Times: ShoreWindow
Charts, Tables & Beach Planner
Free · In‑App Purchases
Now in 13 languages. Save your shore and see its next low tide window, with daylight, moon and waves, worked out on your phone.
Tide times, tide charts and low tide alerts, built around one question: when is the next low-water window at your shore, with the tide, daylight and moon you want? ShoreWindow works it out on your phone the moment you open the app, then plans the month ahead around it.
A tide chart still leaves the reading to you. ShoreWindow gives you the answer. It is made for people who go to the sea when the water allows: rockpoolers, beachcombers, coastal foragers, shore photographers and dog walkers whose beach is only open at low water.
IN YOUR LANGUAGE
ShoreWindow is in English, Danish, Dutch, French, German, Italian, Japanese, Korean, Norwegian, Portuguese, Simplified Chinese, Spanish and Swedish. It follows your phone's language, or you can pick one in Settings.
THE ANSWER FIRST
• Save a shore and see its next matching window straight away: when it opens, how long it lasts, whether it falls in daylight and whether the tide is rising or falling
• A tide curve with the day's high and low water under every window
• A day-by-day board with the lowest water and the biggest tide ranges marked
THE TIDE WINDOW FINDER
• Choose the conditions you want: how low the water goes, daylight, minimum length, arrival and leaving times, and weekdays
• It searches your saved shores day by day and lists every matching window
• Results are called matches, never safe. ShoreWindow checks conditions. It cannot judge access or sea safety
TIDES WITH NO SIGNAL
• Tide, sun and moon calculations run on your phone, so a remote shore with no signal still gets its window
• Tide stations in 108 countries and territories
• Every tide height shows its station, distance and datum, and stations checked against official tide tables are marked
• Weather, wave forecasts and water temperature need a connection. You can turn them off in Settings
SUN, MOON AND SEA
• Sunrise, sunset, golden hour, moonrise, moonset and moon phase for every saved shore
• Weather and a wave-height forecast where coverage exists
• Water temperature where the station measures it
• Heights in metres or feet
ALERTS AND WIDGETS
• An alert before a window opens, at low or high water, or when it is time to leave
• A home-screen or lock-screen widget with the next tide or your next window
• A short Getting Started guide at the top of Settings
FREE AND PRO
The free plan always shows the next matching window at one saved shore, with seven days of tide curves and times, sun and moon, the Finder for that shore over the next seven days, and one alert. ShoreWindow Pro adds the full 30 days, paging up to a year ahead, unlimited saved shores, the Finder across every shore and the whole month with weather and wave conditions, repeating alerts and calendar export. Choose yearly with a free trial, monthly, or a one-time lifetime purchase.
PRIVATE BY DESIGN
No account and no ads. Your shores, rules and alerts are stored on your device, and backup is free, including to iCloud Drive. Weather and wave forecasts are fetched for a saved shore's coordinates. Tide, sun and moon are worked out on your phone. Anonymous crash and performance diagnostics help fix bugs, and you can turn them off in Settings under Diagnostics.
ShoreWindow is a planning aid for the shore. It is not for navigation or sea safety. Always use your own judgement and local conditions.
