Heredis is is a very popular genealogy program in Europe and has quite a few fans in North America as well. It has an excellent user interface that is very easy to learn. It also has great graphics, both on the screen and on printed reports. Heredis also is available for Apple iPhone and iPad. All versions can exchange data with the other versions so your genealogy data becomes portable.
