Conventional family tree charts are nice when displaying 3 or 4 generations, but require dozens and dozens of pages for only 5 or 6 generations.


Thanks to Infinite Family Tree Explorer’s unique algorithm, you can now draw a compact tree displaying 5 or 6 generations on a single A4 or letter page, or hundreds of people spanning dozens of generations, on a few pages. And even thousands of people spanning millennia with just 20 or 30 pages!


All this without any restriction on the amount of information you choose to display for each person: dates, places, events, descriptions, comments, names and dates of siblings or other spouses etc.


Revolutionary timeline! The tree is laid out horizontally, the left margin representing the present, and the right one the distant past (for an ancestor chart). Each person is positioned horizontally according to his exact year of birth, and a graphical bar is drawn to represent the period he was alive, with optional marks for each event: marriages, birth of children etc. You can now visualize instantly those who lived long enough to see growing their great-grandchildren, and those who had not even the chance to know their own offspring; or those who gave life from the dawn – or till the dusk – of their adulthood; or those who were mowed in their youth during the war years… Directly in your ancestor or descendant chart!


Powerful filters: visually flag every person matching some flexible criteria. For example, flag in red those who were born and died in a specific country or region, and in orange those that were born or died or had any other event in this same country. Or flag those who have lost both parents during childhood, those who married more than twice, or those who died in their 20s during wartime.


Flexibility: collapse some branches to focus on specific people or families; highlight the path between selected remote parents.


Implex support: in many families, some people marry distant relatives, leading to duplicate branches in the tree. Maybe your maternal great-grandfather was the second cousin of your paternal great-grandmother? This means that the complete branch of their common great-grandparents should appear twice in your ascending tree… but Infinite Family Tree Explorer detects this automatically, collapses the duplicate branch, and draws a dotted line pointing to the remaining branch. This dramatically simplifies the family tree of royal families, where this occurs repeatedly and recursively!


Smart ordering: when a few branches go up to some glorious remote ancestors, while most of the ramifications are cut off, a traditionally ordered tree can become very tortuous; the smart ordering algorithm keeps your tree graphically balanced, harmonious, and easy to traverse.


Infinite Family Tree Explorer is a complementary app: create and update your database using your favorite genealogical software or website, then import standard GEDCOM data into the app to display your graphical tree. No database editing feature is provided in the app itself, ensuring the integrity of your data.
