Does it have a tide chart, not just a table?

Yes. The home screen is a full 24-hour tide chart with a marker for now and every high and low tide. People told us "no graphs = not very useful", so the graph comes first.

Does it work offline?

Yes. Tide times are calculated on your phone from harmonic constants, so it works on piers, boats and beaches with no signal. No account or sign-in.

Can I see more than the next five days?

Yes. The calendar shows the first high tide for every day of the month, and you can swipe the chart to any date.

Is there a 12 hr time option?

Yes. Choose 12-hour or 24-hour time, feet or meters, and MLLW or mean sea level in settings.

Will it show tide changes when in different areas or countries?

Yes. About 8,700 stations across the US, Canada, Japan, Europe, Australia and more, each shown in its own time zone with daylight saving handled. Korea is not covered yet.

Can I save my favourite place and local beach?

Yes. Star any station and switch between favorites with one tap. The widget shows the next tide for your favorite.

Can I use it for navigation?

No. Ebbline shows predictions only and is not for navigation. Predictions do not include weather, storm surge or river flow.

Yes. Every feature, including alerts and the widget, is free and supported by ads.

Why tide times differ from your beach

A tide table is a prediction for one station. The farther your beach is from that station, or the deeper it sits inside a bay or river, the more the timing and height shift. Add weather, and a difference of tens of minutes is normal. Reviewers have described docks under water when the table said otherwise; this is usually why.

Five reasons for the gap

Station distance: the nearest station may still be miles from your beach.
Geography: tides arrive later, and at a different height, inside narrow bays and estuaries.
Weather: strong wind, low pressure and storm surge push water above or below the prediction.
Time zone and daylight saving: a wrong zone shifts every time by exactly an hour.
Datum: MLLW and mean sea level give different height numbers for the same water.

How to close the gap

Pick a station with similar geography, compare it with the real water a few times, and remember your offset, such as "our beach runs about 20 minutes late". Allow extra margin on stormy days.

How Ebbline helps

Ebbline lists stations near you with their distance and shows times in each station's own time zone, with daylight saving handled. Predictions do not include weather, storm surge or river flow, and are not for navigation.
