Phone or Tablet

The app works on any Android device at level 3.0.3 or above, most phones and tablets are supported. Depending on the nature of your android device, the landscape or portrait mode display may present a more useful size.

Accurate Predictions

This app was written using well-known tidal prediction algorithms and publicly available location data. It can be expected to match very closely to federally-published tide tables. It uses the "Harmonic Prediction of Tides" methodology in long use for tide elevation predictions.

Designed for On The Spot Use

The tidal status presentation gives an immediate snapshot of the tide situation, more useful than just a standard list of highs and lows. The display can be refreshed at any time to update this status. This app is designed for use while actively out and about along the waterfront. It uses large text and the bright color scheme is easily read in the bright sun.

200 Year Calendar

In addition to today's tides, a date picker is available to choose any date from 1901 to 2100. The app does not have to be refreshed on the new year.

Next Day, Prior Day Swipes

Gestures are supported to go to "next day" and "past day" to step day by day through a range of dates. These operate like turning the page of a book. You can quickly swipe through a range of dates to look for good clam digging days.


The selected station can be added to a set of eight favorites. These can be accessed by a down-swipe. Shortcuts cover all states available for this multi-state app.

Selectable Color Schemes

There six display settings, bright, dark, auto day/night, and three others.

Adjustable Display Contents. You can show just the plain graph, or a graph with daylight hours brightened, or a graph with a full sun and moon time display. You can turn the grid on and off as you wish. You can mark a height on the graph with your chosen value and the app will show what time those heights are crossed.

Tide Station Selection. At any time a given state is available for navigation through the location button. You choose a region, then a station. You select another state by swiping upwards and choosing one. Saved shortcuts allow direct jumps to any station in any state covered by the app.

A list of regions and stations for each state can be found at
