Mr. Tides is a Universal application for Mac OS X 10.4 that displays tides and currents for locations around the world. Written completely in Objective-C, Mr. Tides 3 is compatible with both Intel and PPC Mac computers.
Mr. Tides 3 has several changes over the previous version. It uses the Sparkle update engine for seamless updating and the latest XTIDE database engine for access to the harmonics data files. The views are simpler, the database uses Core Data for speed and robustness, and Core Animation is used in the Day view. The maps are now satellite images that can be zoomed for easy station location.
You can still export tides and astronomical information to iCal, and now station locations can be exported to MacENC and GPSNavX via an XML file. Open stations are now documents that can be saved to any location.
