App Smart

Trace your family tree with help of these apps


I am British, Welsh to be exact, which means that if I consulted the right databases and cross-referenced family documents I could probably trace my ancestry back 400 or 500 years.

Nowadays, I can even carry out genealogy research with my smartphone.


Free on iOS and Android

A good place to start is Ancestry.com, which runs a well-regarded app for family trees.

The app is a straightforward way to construct your family tree yourself, by entering data you have already found in family records or online databases.

Building your tree starts with your own entry. You can tap in your name and date and place of birth, or let Ancestry pull the data from Facebook.


Once your basic data are in place, you enter data for your parents, then their parents, and so on. As you do this, the app builds a tree.

You can edit entries, adding extra information such as children or siblings, dates of weddings, deaths, and so forth.

The app compares the information you’ve entered with online databases of genealogical data.

If it thinks entries in your tree are a match to historical information found elsewhere, it will alert you that it has found a “hint.”

You can check to see if information it has found belongs in your tree, or dismiss it if it does not.

If you’re already researching your family history, this slick app could act as a powerful mobile data repository. But it has its quirks.

It partly populates your family tree based on traditional ideas about what constitutes a family and that may not apply to you.

I also found it a bit tiresome to have to go back into a particular entry to add data on relatives.

Ancestry is free on iOS and Android, but to make the most of its features you need to run it in concert with the full Ancestry.com website.


For access to some databases you also have to pay a fee.

The World Explorer data, for example, is $35.


Free on iOS and Android

A great alternative is the free MyHeritage app on iOS and Android. Like Ancestry, it works best when you use it in collaboration with the parent website, but it is still effective on its own. It is similar to and asks for the same sort of information as the Ancestry app, but it is less attractive.

Still, I prefer its interface, which presents each entry in your family tree as a data “card.” To add to a card, you tap it and the card turns over. This graphical trick helps you keep track of the information you’re entering.

MyHeritage also has nice extras, like letting you share smartphone photos.

A research system that uses several types of databases to find information on your ancestors is built into the app. It is powerful — it found the right entry for my father even with limited inputs. It also turned up several hits from a long time ago in Philadelphia, which is interesting because family lore suggests I am related to people who were early settlers there. Access to this system, however, costs $10 annually.

MobileFamilyTree 7

$15 on iOS

MobileFamilyTree 7 is a $15 iOS app that can do the research work without a partner website. It has built-in research databases to help you find historical family data and it can import a genealogy database saved from other family tree apps if you’ve used them before. Its most attractive feature is its 3-D “virtual family tree,” which turns the typical 2-D tree shape into a 3-D graphic that you can zoom around. But entering data is labor-intensive, and some reviewers on iTunes have complained about the quality of the databases, compared to rivals.


One caveat: Be absolutely certain you want to publicly share your family data online, if this is an option in the app. It’s a choice that could affect your privacy.
