01 — Who we are

We're a startup crew of app makers who met from all corners of the world. We pair China's speed and depth in software engineering with a Japanese eye for detail, and make apps for Japan and English-speaking markets.

01

Build in Shanghai

Our engineering home. Swift, servers and AI pipelines move fast here, shipped by a team that loves the craft.

02

Polish in Tokyo

Close to our users. We localise every word, test in the street and sweat the small details that make an app feel native.

03

Ship to the world

Japanese, English and beyond. Character-first design that speaks every language, released on the App Store.

02 — Our apps

Small apps,big feelings.

Characters first.Pixels with personality.

Every app starts as a doodle of a friend. We design characters, turnarounds, sticker sets and UI kits in-house, then bring them to life in code.
