Terrible UI/UX
If you’ve ever done the RYA Day-Skipper theory course, don’t expect this to align with anything you were taught about tidal streams. In fact, just stick to using the almanac.
Even Imray’s charts and tide tables set reference to a set port and follow how you are taught.
yet this app switches between the nearest port, gives an exact time that is either UTC or local so not able to set a constant reference or tidal window. Also it doesn’t allow you to search by lat/lon at a specific time/date you have to drag around and hope you get the right tidal stream.
All this combines to mean that trying to use it for route planning and course to steer predictions can cause wildly differing results.
Stick to manual methods or alternatives.

Broken app
Impossible to drag map to select new locations now. App used to be brilliant, but essentially not working now.
Look elsewhere
Probably one of the most user unfriendly GUI’s I’ve ever used. App was recommended on a training course which we all immediately downloaded. Everyone was left scratching their heads and asking how to access the relevant information. I’m sure the data is there, it’s just like toothache to find it. Even the licensing is difficult to understand. Do you need two purchases, both the stream data and to look seven days ahead. I gave up, there are a number of easier-to-use apps available.

Latest update doesn’t work
The latest update doesn’t allow you to move around the map with IOS 26. Kinda makes it useless now.
Map view issues
The recent update of the app has introduced a glitch meaning you can no longer use the map view on an iPhone . Previously the app worked flawlessly.
