(Note: This post is about Plasma Active, a community collaboration to bring KDE software to consumer devices. To learn more about Plasma Active, read this blog post.)
What is an Active App? It's a project built with Qt and/or KDE libraries that fits into the spirit and use cases of Plasma Active. That means it needs to be touch friendly, preferably present the user interface with QtQuick, have a nice separation between data and visualization where appropriate and integrate well with the platform.
In the Plasma Active meta-project, which includes things like Contour and live OS images, we're building up a small army of such apps in the hopes that those projects can learn from each other and us from them. It will also help ensure that when someone goes to use a Plasma Active device, they don't just have the Contour user experience but also a host of useful stand-alone applications as well.
I announced our first Active App a couple weeks back: Calligra. Today, we add another to the books: Marble!
Marble has already had a mobile version for some time, and since mapping is very important functionality for devices you carry around with you it was only natural for Plasma Active to meet Marble.
There is a project going on right now to provide a QtQuick interface to Marble, and we will be including this effort in the live images as it matures.
