User reviews

Wouldn't be without it, excellent app.

This is one app i use all the time. And,with other corrobrative sources of info, rely on heavily. Both pre-trip planning and especially when at sea. Even more specifically, on the French side of the Channel & Channel islands, where tides are more dominant. You can very quickly determine in real-time the options for approaching a coast, and make the best choice. It can save hours of warming up the Planet,punching a foul tide. Would not be without it. Just wish there was a version that covered the full French Brittany & Atlantic coasts, or more, using the French SHOM charts. There is not.

Perfect for me

Our boat lives in the inner basin at Falmouth Marina, accessible for about 7hrs each tide. This App graphically shows me + or - 15 mins when I can leave or return to my berth. Invaluable. As a bonus it shows tides and weather. Of all the Apps on my phone, this is the most useful. Can’t think how it could be improved.

No hassle app

It just works - easy to use and value for money!

Updated useless.

Got to the end of 2025 then stopped. Did not move into 2026. No updates into new year…nothing. Where I was movement in car depends on tides. Remote no signal, so could not download new. Really inconvenient and annoying.

Accurate - 1 improvement please!

I have checked this app randomly against information from tide tables for a Solent standard port and it was spot on for height and times. Checked some secondary ports against easytide.admiralty.co.uk and heights were pretty much bang on, and timings if different were by a few minutes. This was a lot better than a couple of other apps some friends had. SUGGESTION: standard ports stand out in the A-Z ports list (they are capitalised) but once selected to show tide times there should be an indication whether we are looking at a Standard or a Secondary port. (The capitalisation is lost and I have not spotted another indicator)
