Today's Tide

Today's Tide is an Android app for checking tide changes by beach.

View a tide graph for your selected beach in the app, or keep the home screen widget visible for today's or tomorrow's tide flow. Widgets refresh around your selected beach and date, so you do not have to open the app every time you want to check the tide. The graph shows the current time, current tide level, and sunrise/sunset information so you can get a quick sense of the ocean conditions before heading out.
