Open-source user interface for phones, based on Plasma technologies

 Plasma Mobile is an open-source user interface and ecosystem targeted at
 mobile devices, built on the KDE Plasma stack.
 .
 A pragmatic approach is taken that is inclusive to software regardless of
 toolkit, giving users the power to choose whichever software they want to
 use on their device.
 .
 Plasma Mobile aims to contribute to and implement open standards, and is
 developed in a transparent process that is open for anyone to participate in.
