The one and only Tide app that you've been waiting for!. Now with retina display support, works like a charm on both iPad and iPhone. Use TideTrac daily for info on tides, Moon and the Sun. It downloads your tide data and stores them locally for later offline use. Fast, accurate and easy to use. (Note - TideTrac supports coastal US Stations only) Not only does TideTrac tell you when a high tide and low tide event occur on a given day, it is the only app that can tell you the days of a month when the tides are highest or lowest in one quick glance with a graphical visualization. Swipe the graph to the right and view a four day preview of tide graphs. Add multiple tide stations to your favorites list and switch between them easily. Any station marked as a favorite will have their complete tide table downloaded automatically for the entire current year and will be available for offline viewing. Great for taking the phone with you and lookup tide data at anytime even when you don't have internet connectivity. On the first launch, TideTrac will automatically select the nearest station closest from your current location. But if you need to pick a different tide station, pick one easily from browsing the map visually! Advanced feature - TideTrac lets you lookup tides by hour of day (currently available on the iPad version only). For example, if you are interested in visiting the beach at 7 am for a walk, TideTrac can tell you on what days the tide are lowest and highest at this hour. Plan your visits or travel using the easy lookup table. TideTrac comes in a beautiful interface and also tells you the sunrise, sunset times, moonrise, moonset times. Whether you are going sailing or just planning ideal times to hit the beach or interested in finding the best times for viewing tide pools or finding the best times for fishing, knowing the tide level at any given time and day becomes essential. TideTrac presents all of its data efficiently without over-complicating the user interface. It is extremely easy to use. With the convenience of offline viewing, users can take TideTrac to remote locations and continue to view the tide predictions. What is not included in TideTrac is information on currents and local weather.
