ImaJine
an AI-native app studio

A software studio in Seoul. We build apps for partners and for ourselves, from idea to App Store, on iOS, Android, macOS and Toss, with Claude as the engineering team.

Work with us

We take on app projects from partners: a new app, a feature, or a campaign that needs to land inside an app. You work with the founder directly, and the studio runs on Claude Code, so small teams get a full-stack build without agency overhead.

• Mobile apps: native iOS (Swift, SwiftUI), Android, macOS and watchOS, plus mini-apps inside Toss.
• Web and backend: Next.js and Firebase services, APIs, admin dashboards.
• From idea to store: design, build, store submission and operations, including crash monitoring and release automation.
• Partner project example: a campaign integration that let non-logged-in visitors open shared course links in the app, reached by QR from a fashion platform's pop-up store.

How we build with Claude

• Claude Code is our engineering team: parallel agents in isolated git worktrees, with test-first development and review gates before anything ships.
• One developer ships native iOS (Swift, SwiftUI), Android, web and Firebase backends. ShadeWalk went from idea to the App Store in four weeks.
• Claude API in production: per-trade root-cause analysis with Claude Haiku and deeper strategy reviews with Claude Sonnet in our in-house crypto trading bot (running 24/7 on AWS).
• We also build for Claude users: UsageMaster tracks Claude Code usage and quotas on the Mac.
