ABOUT PREDICTIONS
Predictions are based on the harmonic method, using constants from the Hydro offices (UKHO, SHOM, NOAA, BOM, CHS etc). 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. The Hydro offices consider the harmonic methods used in this product appropriate for navigation.

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.

Ratings and reviews

In 2025 the app is worse than 2 years ago. I left 4 stars because, it is really good if fixed. currently it deletes user settings on exit, so re-defaults to local time, deletes custom ports and hull depth settings when restarted. That means all you can rely on is the default tide times, but check whether it has reset to UT or local time each time you use it, as it swaps occasionally - yes, really is that unreliable currently. So sorry to see a good app decline. What a shame. Please fix.

Nice idea, and the graphical view of tide heights is useful. But this is so full of bugs. It crashes on about 50% of uses, it often tells me I have no licence when I have and it often reverts to tides at Dover, when this isn't one of my selected ports. Interface is confusing and payment options are very confusing. Currents uses a very blocky map and doesn't have nearly enough detail. More work needed Imray!

Deeply disappointed with the app purchase of additional tide tables. It is sold as an annual subscription but does not give you the years tide tables, just the current month. I consider this to be downright deceptive and an appalling practice. I'm so disappointed that I will cease using the app and find an alternative, giving up on the money I've been conned out of. I expected better from Imray.
