取辰
A focused software studio building considered tools for the Apple ecosystem.
一个专注的软件工作室，为 Apple 生态打造经过深思的工具。
We are a small team in Xiamen working on a single conviction: the software you use every day deserves the same care as the things you keep on your desk.
Keychar is the studio name of Chuchen Technology (Xiamen) Co., Ltd. We design and engineer software end-to-end — research, interaction design, type and motion, native engineering, App Store and Google Play delivery, and the post-launch craft of listening to the people who use what we make.
We work primarily on Apple platforms because the design discipline they invite matches the way we like to work: slow iteration, sharp typography, honest defaults, fewer features that work better.
Keychar 是 取辰科技（厦门）有限公司 的工作室品牌。我们从研究、设计、原生开发到上架运营完整闭环交付软件产品，主战场在 Apple 平台。我们相信少而精——做更少的功能，做到更好。
原生应用开发
Swift & SwiftUI for iOS, iPadOS, macOS, and visionOS. Kotlin for Android. We ship to the App Store and Google Play as first-class delivery targets and treat each platform on its own terms.
产品设计
From research and information architecture to interaction, typography, and motion. Our deliverables are not screens — they are decisions, captured and ready to ship.
技术研究
Small research bets on emerging platforms — spatial computing, on-device inference, novel input. We keep what we learn and we publish when there is something honest to say.
A focused space for deep work. For iOS, iPadOS, and Android.
iFocuspace is our first shipped product — a quiet workspace that helps you start a single deep-work session and stay in it. No streaks, no badges, no manufactured urgency. Just a clean room for one task at a time.
