TideApp brings tidal data right to your desktop. The application displays the current tide conditions, along with daily highs and lows with their accompanying times. Will support multiple instances, so feel free to add 3 or 4 or dozens of widgets to your Dashboard!
KINGADROCK Very nice layout. Clean design that looks great next to Apple's Weather Widget.
I wish it had the option to show two days of tides though. Perhaps arrows at the bottom to view the next and previous day's tide information. (Version 1.3)
Just one suggestion, and you might be on this already, whether the tide is rising or falling it is always graphically displayed as rising. Could I be missing something? To clarify the presentation, the arrow could be replaced with a square or, if you're up for a challenge, the arrow could change direction to indicate rising and falling tides.
