Your family's story disappears in a single generation if no one writes it down. Jokbo World turns the Korean family register — the jokbo — into something you can build, carry, and share from your phone. Add people as cards, connect them, and the generational chart draws itself. ■ WHO IT'S FOR · Anyone who wants to preserve the stories their elders told them · People curious about their surname's clan seat (bongwan) and founding ancestor · Clan associations and family gatherings that need relationships mapped out · Parents who want to show their children where the family came from · Anyone digitizing an old paper jokbo before it falls apart ■ WHAT YOU CAN DO · Build your family tree Add a person card, then link parents, spouses, and children. The multi-generation chart lays itself out automatically. Pan and zoom freely, or jump straight back to your own card at any time. · Record each person properly Keep Chinese characters, birth and death years, generation rank, titles, photos, and notes together, so a name becomes a life. · Export to PDF Save your completed tree as a PDF to print for a family gathering or send to relatives. · Search surnames and clan seats Look up Korean surnames and their clan seats to trace where your family began and who its founding ancestor was. · Find historical figures See notable figures in history who share your clan lineage. · Family community Share tips and family news with other members through the feed and boards. ■ HOW IT WORKS 1. Sign up, then open the Tree tab at the bottom. 2. Tap [New] to clear the sample tree. 3. Start from yourself and add your parents and children one by one. ■ PRICING · Free for up to 20 people in your tree. · Need a larger tree? Upgrade with a one-time in-app purchase. · The free version shows a banner ad at the top of the screen. Purchasing a plan removes it. · Your tree is saved to your account, so it follows you to a new device. A single name written down today outlives everyone who remembers it.
