I was walking through Seoul on a slow afternoon when I stopped in front of a small stationery shop. The kind that sells linen-bound notebooks, slim pens, single ceramic mugs. The window was warm cream and dusty plum. The objects inside looked like they belonged to someone who took quiet things seriously. I stood there longer than I meant to. By the time I left, I knew what kind of app I wanted to build. One that felt like that window.
The reader I had in mind reads in cafés. She journals occasionally in a notebook with a soft cover. She stacks books by color on a small shelf and lights a candle in the morning. She finished Attached at twenty-four and underlined too much of it. She texts the lines she loves to one specific friend. She wants to read more. But she doesn’t want to be measured for it. She tried Blinkist once and felt like she was being trained. She wanted an app that felt like a friend who reads, not a coach who tracks.
So I built one book a day instead of a catalog. The big book apps offer thousands. Most readers get through twenty before forgetting them all. I wanted the opposite. One nonfiction summary every morning. Eight to ten minutes. A little longer if you linger. The library grows by one a day, the way a real shelf grows. There’s a quiet arithmetic in this: a year of reading becomes a year of books that stayed.
Underneath the daily summary, there’s an SM-2 spaced repetition algorithm doing quiet work. The flashcards return on the days your brain is most likely to drop the idea. No streaks, no XP, no levels. Just the lines coming back when they’re useful. The algorithm is the only part of the app that performs effort visibly. And even that, it does invisibly.
Darak is the romanization of 다락, the Korean word for an attic. The small warm room above the rest of a house, where things you care about live between visits. A loft, not a dashboard. I chose the word before I chose anything else about the product. Every decision after that had to fit inside it.
Warm cream backgrounds, plum text, berry accents in handwriting (Caveat). Literata for the serifs. Plus Jakarta Sans for the small functional moments. The color palette comes from the Seoul shop window: cream, dusty plum, soft sage. The reader I built for would not trust an app that looks like a fitness tracker. She would trust one that looks like a book she’d buy. So that’s what I made.
No streaks. No XP. No daily target. No leaderboards. No AI chatbot to discuss your reading with. No badges, no titles, no tiers. No social feed. There are share cards, for sending one line to a friend, because that part is true to how this kind of reader shares. Everything else was deliberate. Each addition would have broken the trust I was trying to build. The app you don’t add things to is the one people stay in.
if you got this far, that’s the whole thing. one book a day, kept close.
