Good app, and thanks to earlier reviewers!

When I first fired up Tides, it immediately closed, as other reviewers mentioned. They also mentioned how to fix the problem, tapping the icon along the bottom to bring up the screen where you pick the location. I didnt even switch from Auto mode to a manually chosen location -- just going into this screen seems to have fixed the crash-on-launch problem. Tides is a very useful app for me now, and even better for my rockhound girlfriend!
