The next generation iRegatta has been released.
The original iRegatta app was launched back in the autum of 2009, before the iPad was on the marked. It has always been a focus point not to introduce features than couldn't also work well on an iPhone.
In iRegatta 2, this has changed. It's an iPad only app taking advantage of the bigger display. It's been rebuild entirely from the bottom, focusing on a more flexible user interface, where the user can customize the layout to serve his needs.
Take a look at some of the tutorial videos her: iRegatta 2 , to get an idea of how it works.
