Arbor: Family Tree & Genealogy

Arbor is a beautifully simple family tree maker for iPhone and iPad. Build your genealogy, map your ancestors, and keep your whole family history in one private place — with no account, no subscription, and no cloud required.

Unlike the big genealogy services, Arbor keeps everything on your device. Your data stays yours.

KEY FEATURES
• Build your tree — add parents, children, partners and siblings from anyone's card or right from the tree, and watch your family chart grow across generations.
• Visual family tree — explore a clean, automatically arranged view of your entire lineage. The Ancestors view shows one person's ancestors, five generations at a time.
• Relationship finder — pick any two people and instantly see how they're related: cousin, great-uncle, in-law, and more.
• All relatives — everyone related to one person, grouped by kinship and closest first, up to third cousins or filtered to an exact degree.
• Ancestor fan — the classic pedigree fan: one person at the center, up to five generations of ancestors around them, Sosa-Stradonitz numbering, and an empty slot held for every ancestor still missing.
• Life timeline — birth, marriages, the birth of each child and death in date order, with the age at every event.
• Upcoming birthdays — who is next in the year ahead, in how many days, and the age they're turning. With a reminder, if you want one.
• Tree check — eight kinds of problem, from a death before a birth to a circular family link, sorted into errors and warnings.
• Find duplicates — the same person entered twice, grouped by how likely the match is. Merging the cards loses no link and fills the empty fields.
• Marriages and adoptive parents — a wedding date and place, a divorce or separation, and parent links you can mark as adoptive. Both travel through GEDCOM.
• GEDCOM import & export — bring in data from any genealogy service via the standard GEDCOM format, and take it with you anytime: now with places, occupations and notes in both directions.
• Big trees — past 1,000 people the tree opens as a map, already centered on its most crowded area, with pinch to zoom and a tap for anyone's card. Tested on trees of 24,000 and 50,000 people.
• Fully offline — no internet, no login, no waiting.
• Your data, exportable — back up or move your tree as a standard JSON or GEDCOM file whenever you like.

Arbor Pro — a one-off purchase, never a subscription — opens the tree and the tools beyond the first 10 people.
