This also gives you access to tidal stream data for the UK and France. If you want to broaden access to tidal data for any day of the year across all the territories, then you need an additional Hydrographic Office licence, costing an extra £4.99. If you want to look ahead, you have to buy a £3.49 licence for the calendar year, which allows you to see six days ahead in UK waters, the current day in France, and any day of the year in Italy, the USA, Australia, New Zealand, and a handful of others.
It shows you heights and times, neaps and springs, and has a tidal curve that allows you to set a horizontal line for your minimum depth to illustrate when you have to clear out.Ī vertical line lets you walk through the day’s curve, showing depth and time at different points.

Imray’s tides app is free to download and covers 8,000 global locations, with no network connection required.
Nor is it always specified whether the apps use UTC or local time, which can give rise to errors of an hour. Remember, errors can be magnified in areas of eccentric tidal behaviour, notably the Solent where there are two high waters and a very rapid ebb. Not all tidal apps offer the same level of support, so check the the apps covers the area you sail. Some do this free of charge and offline, but better-designed and more powerful apps will also provide a tidal curve you can interrogate, to visualise the remaining rise or fall of tide, though some of these are generic curves that require some caution. The most basic of tidal apps will provide heights and times that will allow you to figure out when to depart, round a headland or how deep to lay your anchor.
There is a huge range of inexpensive tidal apps to choose from, although most of the best tidal apps charge a subscription fee.
