Haeun Cho
Dohwa, 2024
Ships the drawing and capture lane. Used to run a print shop that never printed on time.
[1] Time, asset, health, speech, solve, family, luck, event — one calendar, no extra OS.
— YeodeolYeodeol (여덜) is a life operating system. The number is the product: eight domains that share one clock, one identity, and one place to look.
Around that OS we ship small apps — cooking, water, radio, mental, companion. Each one talks to the same day, not a new silo.
If it does not sit on the calendar, it is not in the day.
We keep money in won, time in Seoul, and names in the domain they belong to.
Eight lanes is enough. A ninth is usually a duplicate.
The OS should feel quiet. The apps can be loud.
Health is yellow. Family is white. Don’t invent a new palette for a mood.
Ship the day you are in. Yesterday’s backlog stays backlog until someone asks.

Hansang, 2023
Keeps meals, markets, and two-person portions honest. Once recooked a week from a spreadsheet.
Mulsave, 2024
Water, reminders, and the quiet health ticks. Built three failed hydration apps before this one stuck.
Kongkong, 2025
Companion loops and small rewards. Treats a streak as a receipt, not a personality.
Note
Weeks and months are views. The truth lives on a Seoul date, in the domain that owns the block.
No pitch deck required. A day you already live is enough.
