SudoZoo is our first app and it is in development now. Store links and details will appear here when it launches.
Independent app studio
Small apps, made with a lot of heart.
XinKai Studio designs and builds friendly, thoughtful apps for iPhone, iPad and Android. Our first app, SudoZoo, is on the way.

How we make things
XinKai Studio is a small, independent studio. Every app is designed, built and supported by the same people.
Simple to use
Clear screens, big buttons and no clutter, so anyone in the family can pick it up.
Private by default
We collect as little as possible and explain exactly what we do in plain language.
Looked after
We keep our apps updated for new devices and answer every support email ourselves.
