I rely on this app daily and find its simple interface easy to use and read. A really cool function to add would be an alarm or notification of some kind that you could set to tell you when tide is high, low or at a certain level in between tides. For instance, I can point my sea wall on an outgoing tides after the tide drops under 6. If the app could be set to inform me when it reaches that level, it would make my life easier.
