iStreams - Channel Islands

iStreams displays the valid hourly Channel Islands tidal stream atlas for the current UT time , in reference to the current UT time of high water at Dover... a smart app, fully functional offline.

The nearest Dover HW time (UT) from the actual time (UT) is selected from the database and the relevant streams chart is displayed, together with the time period for which the chart is valid.
As the time moves to the next valid period, the relevant hourly chart is auto displayed.

* Swiping left or right on the chart (or tapping the ← → buttons), displays the next or previous hourly chart.
Whenever the chart displayed is valid at the current time (UT), the validity period is displayed in green.
* Pinching the screen zooms the chart

Select 'Channel Islands' or zoomed 'Alderney' streams chart, from the segmented control.

Tap on the interpolation button to display a Springs/Neaps scale, here you can auto calculate the tidal rate when in between neaps and springs.

For forward planning, tap on the date to select a different date, whereupon data relevant to that date will be displayed.
