Tides Planner for Android

11 things about Tides Planner

1. There are differences between the app predictions and the official Hydro office tide tables, as these are based on large numbers of constants that are not made publicly available.

2. Predictions are based on the harmonic method, using constants from the Hydro offices (UKHO, SHOM, NOAA, BOM, CHS etc).

3. Essential TIDES tool for sailors, divers, canoeists, fishermen, surfers, swimmers, photographers and anyone involved with sport or leisure at the seaside.

4. Some countries have time limits from the national Hydrographic Office.

5. - Denmark, Spain, Portugal, South Africa, Oman, Argentina: SEVEN DAYS at a time.

6. Always consult tidal curves and take into account local weather (pressure and wind) and swell conditions, which can have a very significant effect on sea water levels.

7. - Italy, USA, Canada (main ports), Australia, New Zealand, Japan and other countries: ANY DAY in the year.

8. From version 3.0 enhanced predictions for Europe based on our own constituent analysis system.

9. Advanced users can take advantage of extensive tools to calculate time windows for entering/leaving and clearing depths.

10. The Hydro offices consider the harmonic methods used in this product appropriate for navigation.
