Add people, relationships, dates, places, photos, and sources. AncestorOS keeps your tree organized, private, and accessible everywhere.
Add as many family members as you need. No tree size limits on paid plans. Add relationships with two taps — parent, child, spouse, sibling. AncestorOS handles the structure so you can focus on the people.
Names, dates, places, photos, notes, and source citations. Each person gets a full profile with their own page. Attach birth certificates, census records, and photographs. Nothing gets lost.
Your tree is yours alone. Nothing is shared to a public network. No crowdsourcing your family data to strangers. AncestorOS never uses your data to "suggest hints" from other users' private records.
Start with yourself and grow at your own pace. There is no right order, no required fields, and no deadline.
Create your own profile with your name, birth date, and birthplace. This becomes the root of your tree. You can always add more detail later.
Work backwards one generation at a time. Add names, dates, and places as you know them. Leave unknowns blank — you can fill them in later as you research.
Branches expand naturally. Add siblings, their spouses, their children. The tree grows with you over months and years of research.
Built for real genealogists — hobbyists and professionals alike.
No caps on paid plans. Add every cousin, great-grandparent, and distant relative you discover.
Each person gets a profile photo and a full photo gallery. Portraits, documents, and group photos — all in one place.
Cite every fact. Attach sources to births, marriages, deaths, and events. Professional-grade documentation built in.
Full functionality on iOS and Android browsers. Add a person at a family reunion, right from your phone.
Install the PWA and browse your tree without an internet connection. Changes sync when you reconnect.
Export your entire tree as a standard .ged file at any time. Use it in any other genealogy software — no lock-in.
Free plan available. No credit card required. Your first 50 people are on us.
