Needs charts


Good app but this needs charts that tell you sunrise sunset times low tide, high tide times with Heights daily for the week and several weeks even! This app is designed well but it’s missing this key chart information. The only way to view it is to scroll through and observe their interactive graph but that’s way too time intensive and unfeasible. They just need one page I can scroll down and view several days of information in a chart at least two weeks ahead. I’m having to use another app to do this :-( also their feedback func doesn’t work because I don’t use the email app on my phone. Should work with Gmail.

Local tides


Having this information at my finger tips is such a fantastic tool. I know when to launch my row boat and which direction to go. Never have to ho against the current makes rowing so much easier. Many thanks for the developers.

Love it!


It gets straight to the point. Very user friendly, can bookmark your locations. I absolutely love that as soon as you open it, it tells you the time and tide for that precise moment.
