Your family history,
in your pocket
Your tree, the stories behind it and your research log, on your phone. The app signs in to the same account you use on ancestoros.com, so whatever you add shows up everywhere.
Free to download. Works with your Hobbyist or Pro plan.
Built for the places research actually happens
Family history rarely happens at a desk. It happens when an aunt starts talking, at a reunion, at the archive counter, and on the drive home. The app covers those moments, and the website is still there for the long evenings.

At the kitchen table
When the stories start, write them down
Open a memory, type what you are hearing, and tag the people it is about. The shoebox of letters, the recipe, the story about the wheelwright's yard: each one lands on the right person in your tree.
- Write memories and tag family members
- Photograph old prints with your camera
- Browse the tree and a five-generation fan chart

At the family reunion
Add the cousin before you forget which side they are on
Search everyone in your tree, add a new person in a few taps, and connect them to their parents on the spot. By the time you are home, they are already on the web.
- Add and edit people
- Connect parents, children and spouses
- Work out exactly how two people are related

In the archive
Log the search while the film is still in the reader
Record what you searched, where, and what you found, including the searches that turned up nothing. Photograph the document and link it to the person it is about.
- Research log entries, found or not
- Document capture, linked to people
- Citations, obituaries, burials and clippings

Between visits
Birthdays and anniversaries come to you
The home screen shows who is coming up, and the app can remind you on the day: a great-grandmother's birthday, a wedding at the parish church, ninety-nine years on.
- Reminders for birthdays and anniversaries
- Research tasks and a timeline of events
- Discoveries to accept or dismiss
