Ratings and reviews

nice app, looks detailed and well designed with lots of info. My only issue is that when I change the units it's not reflected in the insights panel, only the cards at the bottom

Edit* It is so much better an accurate now 5 star app* (worst app ever off by an hour not accurate to anything being reported from the live station report there is no times of tide besides the next two day tides. only time chart graph for that day which is also very inaccurate)

Really easy to use, I photograph sea birds and it's a great help getting to the beach at the right moment.
