Apps that grow
with you.
LeafWork Studio builds focused, beautiful apps for iPhone, iPad, and Mac. We believe great software should feel like a natural extension of your thinking — quiet, reliable, and always ready.
Tools we’re growing.
Each app is designed to do one thing exceptionally well — with native performance and care in every detail.
KanjiMate
From N5 to N1, one card at a time.
Your daily JLPT Kanji companion — flashcards, quizzes, and stroke-by-stroke handwriting practice with smart spaced repetition and iCloud sync. All 2,230 kanji are free to read, with no ads anywhere in the app.
LineSmith for Xcode
The commands Xcode forgot to ship.
A free Xcode source editor extension with 31 line- and Swift-source editing commands — move, sort, join, split, trim, organize imports, generate initializers — in Xcode's own Editor menu. No account, no ads, no tracking.
Small studio, high standards.
We’re an independent studio focused on quality over quantity. Every decision — from architecture to animation — serves the people using our apps.
Native First
Every app is built with Swift, SwiftUI, and platform APIs. No cross-platform shortcuts — just smooth, native experiences.
Thoughtful Design
We obsess over details — typography, spacing, motion — so every interaction feels intentional and delightful.
Built to Last
Offline-capable, privacy-respecting, ad-free, and never subscription-gated to be useful. Tools that work for you, not against you.
Something new is growing.
