Arbor: Family Tree & Genealogy

About this app

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. • 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. PRIVATE BY DESIGN No ads. No tracking. No account. Your ancestors and relatives never leave your device unless you choose to export them. WHO IT'S FOR Anyone tracing their roots — from a quick family chart for the kids to a growing genealogy project spanning many generations. Start your family tree today and watch your roots come to life.

Arbor 1.1.1 makes it much easier to connect the people you add, and fixes a relationship label. • Connect as you add — the + button now asks who the new person is related to: a parent, child, partner or sibling of someone already in your tree. No more people stranded on the top row. • Build the family faster — create a new partner or add a sibling straight from anyone's card. A new child is linked to both parents, and a second parent becomes the first one's partner. • Add from the tree — press and hold anyone in the tree to add a parent, partner, child or sibling right there. • Fixed — an uncle's wife is now an aunt-in-law, not an uncle-in-law. The same goes for the spouses of nephews, cousins and grandparents. • Fixed — the date of death entered when adding a new parent or child is now saved. • Search by surname and first name — type both, or just the first letters, in any order. Essential when many people share a name. • See how two people are related — the relationship finder now shows every closest common ancestor and the full line from them down to each person, with names and years. • Readable ancestor fan — full names with years of birth and death instead of initials. Scroll to explore up to five generations; tap anyone to open their card. • More faithful GEDCOM import — people recorded as deceased without a date are no longer shown as living with an impossible age, the main name is kept instead of an alias or nickname, and French Republican calendar dates are read. Re-importing the file refreshes the names. • Clearer tree — first and last names are equally readable, long names no longer overlap in very large trees, and lists show years of birth and death to tell namesakes apart. • Honest dates — a date known only by its year, or as “about 1850”, is now shown that way instead of as 1 January 1850, and no longer produces a birthday. Set it yourself with “What is known” when editing a person. Trees saved by earlier versions open exactly as they did before.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
