Put DUKAI on your phone
Installing puts DUKAI on your home screen and opens it in its own window, without the browser around it. It is the same website, signed in as the same account, with the same recipe book, kitchen and shopping list. Nothing is downloaded from an app store.
On this device
The DUKAI app is a different thing
A native DUKAI app for iPhone and Android exists in the code base and talks to the same account. It is not in an app store yet, and it is not what this page installs. When it is released, it will be said here. Until then, the installed website is the way to have DUKAI on your phone.
