Every family has a grandmother who remembers things nobody else does, an uncle with stories that have never been written down, a great-aunt who is the last person alive who knew your grandfather. KinFlash is built around a simple idea: those stories matter, and they are worth preserving before they are gone.
You start by building your family tree on an interactive canvas. Tap to zoom in on a generation, drag to pan across cousins and in-laws, tap a person to see their details and relationships. The tree is stored locally on your device first — your family history is yours, not a cloud company's.
Once you have a few people in your tree, KinFlash generates flashcards automatically from the relationships you have entered. One side of the card asks "Who is Maria's mother?" and you flip it to see the answer. It sounds simple, but running through a deck before a family reunion will surprise you — you know the names, but the connections get fuzzy. The cards refresh as your tree grows, so there is always something new to learn.
When you are ready to share or archive, KinFlash exports your tree in GEDCOM 5.5.1 format — the standard genealogy interchange format accepted by Ancestry, FamilySearch, MacFamilyTree, and dozens of other apps. You are never locked in.
An optional cloud sync keeps your tree backed up and lets you continue on another device. If you prefer to stay fully local, that works too — nothing is required.
Coming soon: an AI-guided interview mode powered by Apple Foundation Models will let you have a conversation with a relative and have KinFlash extract the names, dates, and relationships automatically and add them to your tree.
Built with care by a solo developer who wanted his own family's stories to survive.
