About us

We build calm, purposeful Korean apps

J.WANTPLAN is a Seoul-based husband-and-wife studio behind MealLog (식단 착착), MoneyTrack (가계부 착착), TodayDo, and small experiments that make planning daily life lighter.

Studio story

We are a husband-and-wife development studio based in Korea. We work together through every step of idea development to create practical and meaningful services. What we pursue is a good 'plan'—and we bring that plan to life.

From Planning to Design and Development

We don’t just build apps—we design better experiences. We solve users' problems and deliver meaningful services.

How we work

Research sessions, interviews, and data from our live services inform every plan we make. We only ship flows that solve a real routine for families and independent creators.

Each release includes localization (Korean, English, Japanese), accessibility-friendly components, and analytics so we can keep improving after launch.

Product research & positioning

Problem framing workshops, competitor scans, and naming that expresses a clear benefit.

Experience & interface design

We design flows people can use without hesitation—interfaces prioritize context and behavior over screens and features.

Full-stack development & operations

Vue, React, NodeJS, and Flutter power dependable releases, along with analytics and store operations.
