When the Watch was announced, i couldn’t wait for a tide complication. Finally, this app delivers and it works really well. I’ve used the small complication and wish the Large Modular complication had a countdown to the next tide next to the actual time. There’s room for it and and would be extra helpful. Example below.
Tide Location
Low Tide (.23 ft)
5:23pm (-2:30)
