iStreams - Thames Estuary

Real time tidal streams for Thames Estuary

iStreams displays the valid hourly Thames Estuary tidal stream atlas for the current real time, in reference to the time of high water at Sheerness... a smart app, fully functional offline. With tools to measure tide set and interpolated rate.

The nearest Sheerness HW time to the actual time 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 on the chart, displays the next or previous tidal hour chart.

* Whenever the chart displayed is valid at the current time, the validity period is displayed in green.

* Pinching or double tapping the screen, zooms the chart

* Select Local or UTC time.

Select the rate tool to auto calculate the interpolated tidal rate when in between neaps and springs.

The app automatically selects the nearest Sheerness HW time of the day, but if you want to see data for the next or previous HW of the day, swipe forward or back to advance the tidal hour.
