Indie studio · Seoul, Korea

Warm, helpful apps.
Made slowly, with care.

Hi, I'm a solo indie developer building small, gentle apps that help people manage their everyday life with mental health and companionship at heart.

Bavi In the workshop

"Help me start what I keep avoiding."

A calm little beaver for tangled to-dos, Bavi untangles overwhelming tasks into small, clear steps, picks the one piece that fits right now, and keeps you gentle company while you start.

  • Untangle any task
  • One small next step
  • Assisted focus sessions
  • Kind replanning when stuck

You don't need to build everything right now. Just place the first piece.

Tochi helps you feel. Bommi helps you stop. Bavi helps you start.

Why "Lazy" Hippo?

Slow is not a bug. It's the feature.

Lazy Hippo Development is a one-person studio based in Seoul, Korea. I believe technology should feel like a friend who sits beside you not another thing shouting for your attention.

Every app I make starts from the same questions: Does this make someone's day a little softer? Does it respect their pace, their privacy, and their peace of mind? If the answer is yes, the hippo gets to work. Slowly. But it gets there.

  • Mental health first

    Designed to reduce stress, never add to it. No dark patterns, no guilt mechanics.

  • Companionship

    Every app has a small friend inside cheering you on through everyday life.

  • Helpful by design

    Practical tools for real routines built to genuinely make a change, however small.
