The studio

We design and develop our own apps.

Our current project is Koi Kanji Widget for Android. Its home-screen widgets show kanji; in the app, you can check readings and meanings and practise in short sessions.

Kanji on your home screen

Koi pairs a customisable widget with exercises for readings, meanings, vocabulary and writing. Meet a kanji when you unlock your phone, then explore it further when you have time.

Readings, vocabulary and examples

Entries bring together On and Kun readings, words, example sentences and stroke order. JLPT filters help you find material at the right level.

Favourites, collections and progress

Organise review with favourites, hidden or viewed kanji and collections. Progress and areas to reinforce help you decide what to revisit next.

Customisable widgets

Choose themes, colours and widget options. We care about readability and a consistent feel between the app and your home screen, across widget sizes.

Your data stays on your device

Koi keeps your organisation and preferences on your device. Preserving favourites, collections, settings and progress when the app updates is a development priority.

Development and updates

Koi is in closed beta. We are reviewing the experience, polishing details and improving features before expanding availability. Feedback and issue reports help.
