Everything you need...
...and so much more!
A solid core
Ubuntu Touch comes pre-installed with a set of solid core apps that cover your daily needs. This includes everything you expect from a phone, like a dialer, contacts and calendar, but since it's Ubuntu, the OS comes with a fully-featured file browser and terminal (including essential command-line applications) as well.
Convergence in mind
Ubuntu Touch was created to converge the worlds of mobile- and desktop-computing, and that's also true for its applications. All apps are created with convergence in mind and can automatically adapt to screens from the smallest phone to the biggest tablet, and even work in window-mode on the desktop.
