The latest version available is Clock App 1.0, which has been recently released, bringing some fixes and graphical interface updates. It is finally ready to be released with Ubuntu Touch, on the 17th of October.
In this article I will show you how to install and test Clock App 1.0, on Ubuntu 13.10 Saucy Salamander and Ubuntu 13.04 Raring Ringtail.
Because the Ubuntu Clock App and the needed dependency (Ubuntu SDK) are available via third party repositories, installing Ubuntu Clock App 1.0 on the latest versions of Ubuntu available is easy. Just add the needed PPAs, update the local repository index and install the ubuntu-clock-app and ubuntu-sdk package. Like this:
$ sudo add-apt-repository ppa:ubuntu-sdk-team/ppa
$ sudo add-apt-repository ppa:ubuntu-touch-coreapps-drivers/daily
$ sudo apt-get update
$ sudo apt-get install ubuntu-sdk ubuntu-clock-app
