Heredis.com is a desktop family tree software program that originated in France. I have been aware of the program for many years. It was introduced in 1994 for the Apple Macintosh operating system. See Wikipedia: Heredis for the background to the company. Representatives from the company have been attending the RootsTech Conference in Salt Lake City, Utah for the past few years. But, the program is not yet well-known in the United States despite its popularity in France and throughout Europe.
Quoting from the English translation of the French Wikipedia article linked above with some alterations to correct the translation:
In February 2018, the startup participated for the first time in "RootsTech", the global genealogy fair held in Salt Lake City , the world headquarters of The Church of Jesus Christ of Latter-day Saints . It presented a special edition of its software: a version for Americans which complements the database of FamilySearch , the largest genealogical organization in the world created and administered by The Church of Jesus Christ of Latter-day Saints.
The Windows version of the program costs $29.99 and the Mac version costs $49.99. There is a free version that is limited to 50 people in your family tree.
One of the most interesting and useful features of Heredis is the ability to search for information about any one in your Heredis family tree from hundreds of archives and major online genealogy websites at the same time. This tool is very impressive. Here is a screenshot of some of the archives the program searches.
