The San Juan Islands in Washington State, USA, is a boating paradise. This app provides tide and current predictions for the area. There are 41 tide stations and 55 current stations.

The predictions are immediate. There is no loading from the internet, all tide and current data are built into the app.

The chosen area is covered by the nautical chart #18421 "Strait of Juan de Fuca to Strait of Georgia". You can view the selected station on this chart, initially displayed in full, you can zoom and pan to see full detail of the chart.

A date entry screen allows you go see the prediction for any date. You can also swipe left and right to go forward and backward a day at a time.

There is a favorites system, you can save up to eight locations for immediate access by a down swipe.

Full sun and moon information is available if desired, you can also just show the daylight range, or simply the tide table and graph by itself.

To select your desired station, use the location button. A list of regions

will be displayed. For current stations, the region names are bodies of water,

such as Strait of Georgia - Currents. For tide stations, the region names

are land areas such as Strait of Georgia - Tides.

Choose one of these, and a list of stations is displayed. Choose a station,

then the tide or current table for the present date will be calculated and displayed.

A display is produced showing the entire San Juans nautical chart, which includes an inset station name, and line to the location, and a dot representing the station. The map is small but it shows the location within the entirety of the San Juans. At that point, you can use pinch and pan gestures to zoom into the station and see the chart detail as you wish, there is sufficient chart resolution during zoom to show the full detail as on the original chart.
