Hourglass
The person you are looking at sits in the middle, with ancestors above, descendants below and partners beside. Tap anyone and the tree glides over to centre on them.
For Mac, iPhone and iPad
A family tree your family builds together.
Names, dates, places, photos and sources, kept in one private tree the whole family can add to over iCloud. No account, no server of ours, nobody else reading it.

No account
Open the app and start. There is nothing to sign up for.
No server of ours
Your tree stays on your devices and in your own iCloud.
Works offline
Add a great-aunt on the train. It syncs when you are back.
Built for big trees
Designed to stay fast with a hundred thousand people in it.
Five views, one tree
See where you come from, from every side.
Every view draws the same people with the same cards, so moving between them never loses your place.
Fan
Up to eight generations in a half circle. Turn it by dragging, and tap a wedge to start from there.
Ancestors & Descendants
The two charts genealogists print most: one half of the hourglass, drawn deeper.
Timeline
Every life on one axis of years. Drag the scrubber to 1914 to see who was alive, with the history of the time shaded behind.
Together
Everyone adds what they know.
Share a tree the way you share a note, from the share sheet, through Messages or Mail. Each relative can read or edit, as you choose. Changes travel through iCloud, with nothing of ours in between.
- Two cousins editing the same person never overwrite each other: facts merge one by one.
- Work offline. Your edits catch up when you are back online.
- What changed since you last looked glows for a moment, so you see it.
- Leave a shared tree and you keep a read-only copy. Nobody loses their work.

Records
Dates as the registers wrote them. Families as they are.
Fuzzy dates, kept as written
Parish registers say “about” and “before”, or give the day in another calendar. Filiation keeps the date exactly as the record has it, and still sorts everyone in the right order.
- about 1858
- Approximate
- between 1788 and 1791
- Range
- 12 Germinal an IV
- French Republican
- 3 March 1712
- Julian
- 14 Nisan 5610
- Hebrew
Every family fits
Nothing in Filiation assumes two parents of opposite sex, a single marriage, or that every parent is a birth parent. Each link between a parent and a child says what kind it is.
- Biological
- Adoptive
- Step
- Foster
- Unknown
Bring your tree
Import GEDCOM 5.5.1 and 7.0 from the app you use today. Export GEDCOM 7 whenever you like.
Your research is never locked in.
Privacy
Your family’s history is nobody’s business model.
Genealogy websites earn their living from records and DNA, so your tree is part of what they sell. Filiation is an app you own: it keeps no account, runs no server and reads nothing.
Local first
The tree lives on your devices and works with no connection at all.
iCloud, if you want it
Sync and sharing go through your own iCloud account, and stay off until you turn them on.
The living, left out
Charts and files you export can leave out everyone still alive.
Native
Made for Mac, iPhone and iPad. Not a web page in a window.
Drawn with Metal 4
The whole tree, down to the last cousin, in one canvas you pan and pinch like a map.
Liquid Glass
Toolbars and controls float over the tree, the way the rest of the system does.
Spotlight
Type a great-grandmother’s name in Spotlight and land on her card.
GEDCOM in and out
Move a tree in from another app, or out to one, in the format every genealogy tool reads.
Charts worth printing
Export any view as a PDF or PNG, drawn from the same cards you see on screen.
Right where you left it
A tree reopens on the person and the view you were last looking at.
