A few years ago, I started noticing something uncomfortable. My contact list was full of names. Hundreds of them. But sometimes I would open a contact and think: When did I last see this person? What did we talk about? Are we still close or just connected? It wasn t that I didn t care. It was that life moved fast, and memory is messy. Contacts apps store numbers. Notes apps store text. CRMs manage data. But none of them reflect how we actually remember people. We remember moments. We remember feelings. We remember how a relationship evolves. So I built Human Timeline. At first, it was just for myself a simple way to log short meetings, voice notes,emotional tags. But once memories accumulated, patterns began to emerge: Who I meet most often Who I haven t spoken to in months Which relationships feel warm and consistent Which ones are slowly fading How emotional tone changes over time It became less about tracking people and more about understanding my own relational behavior. I added features like: Relationship Cube (frequency, recency, emotional trend, consistency) Activity heatmaps Monthly relationship summaries Feeling pattern tracking Network graph of shared memories Side-by-side comparison between people Not to judge relationships. But to see them more clearly. The idea is simple: We don t remember life by dates. We remember it by people. This project is very personal to me. I m curious How do you keep track of important relationships in your life? If anyone s interested in seeing what I built, here s the app: https://apps.apple.com/kr/app/hu... Would genuinely love feedback.
