WORK / Case studies

What we built, and why we built it that way.

We planned, built, shipped and still run all three products below ourselves. Instead of feature lists, each case covers three decisions we made and what came of them.

Because they're our own products, we can show the real screens and measured numbers.

  1. 01 / APP

    Habit app · iOS & Android · KO/EN/JA

    Life-Up

    In-app and web subscriptions count as one, and the backend is split into six services.

    • Service split
    • Two payment systems
    • Three languages
    Platforms
    iOS · Android (one codebase) · web portal
    Languages

  2. 02 / APP

    AI golf swing analysis · iOS & Android · KO/EN/JA

    SwingNote

    Swing videos are analyzed on the phone, never uploaded, and the coaching AI runs on a model we operate ourselves.

    • On-device analysis
    • Self-run coaching model
    • Store review
    Platforms
    iOS · Android (one codebase) · web portal

  3. 03 / WEB

    This website · Web · KO/EN/JA

    laonmon.com

    Each language has its own URL and pre-rendered HTML, so search engines read all three separately.

    • Per-language URLs
    • Real 404s
    • A chatbot that doesn't make up prices
