Case studies

Visual English Dictionary

We built "Visual English Dictionary," an app to learn English in 30+ languages. We focused on UI/UX so anyone can use it easily, adding bookmarks, offline study, dark mode, and powerful search that surfaces related keywords.

We handle everything from planning and design to development and operations.

Yasai App

An app that matches farmers and consumers so people can pick up harvested vegetables right in the field, including purchasing.

Works on iPhone, Android, tablets, and desktop browsers.

Linkmall

A platform where you can sell products just by sharing a link. We made selling easy via SNS and email, and even users without a PC can register products, manage orders, and send shipping notices from a smartphone.

Built after hearing from a local cake shop that starting an online store felt too hard.

STEP4

Review and store submission

After development, you review the app yourself to confirm it matches the agreed features and design.

We then handle submissions to the App Store and Google Play, preparing for review criteria so release goes smoothly.
