The Ubuntu App Showdown resulted in the development of 133 new applications for Ubuntu. Soon, you’ll be able to install these apps from the Ubuntu Software Center and vote on your favorites – the voting decides which apps win.

These are just some of the interesting applications that are being talked about among Ubuntu users. Feel free to browse the full list yourself; I’m sure there are some hidden gems.

Fogger

Fogger creates separate, sandboxed desktop applications out of web apps.

Each web app runs in its own window, allowing you to easily switch between them and launch them from the dash — just like Ubuntu’s new web app integration feature.

Fogger is already available in the Ubuntu Software Center.

LightRead

LightRead is a slick new RSS feed reader for Ubuntu. It works with Google Reader to synchronize your subscriptions and is integrated with other web services, including Instapaper and Pocket (formerly known as Read It Later). Of course, it has offline-reading support, too. Its interface is similar to the popular Reeder application for Macs.

Until it’s available in the Ubuntu Software Center, use the following commands to install it:

sudo add-apt-repository ppa:cooperjona/lightread
sudo apt-get update
sudo apt-get install lightread

GWoffice

GWoffice stands for “Google Web Office” — it’s an application for editing your Google Docs outside the browser. It can download your Google Docs files and re-sync them each time you launch it. There’s also support for uploading certain types of files to Google Drive by dragging and dropping them to the GWoffice icon on Unity’s dock.

Until it’s available in the Ubuntu Software Center, use the following commands to install it:

sudo add-apt-repository ppa:tombeckmann/ppa
sudo apt-get update
sudo apt-get install gwoffice

Cuttlefish

Cuttlefish waits for events to occur and automatically runs user-definable actions when they do. For example, you can create a rule that automatically launches a specific program when you connect to a specific wireless network. You can have your desktop background change when you unplug your laptop or plug it back in. You can set a specific audio volume level when a specific program launches. The possibilities are near endless, as the available events and actions can be combined in any way you like — you can even have an event trigger multiple actions.

Until it’s available in the Ubuntu Software Center, use the following commands to install it:

sudo add-apt-repository ppa:noneed4anick/cuttlefish
sudo apt-get update
sudo apt-get install cuttlefish

Download Monitor

Download Monitor is a utility for people with metered Internet connections (upload and download limits). You can view graphs of your bandwidth usage history and set quotas where Bandwidth Monitor will warn you. It’s also integrated with Unity’s quicklist functionality, so you can view statistics from the dash.

Until it’s available in the Ubuntu Software Center, use the following commands to install it:

sudo add-apt-repository ppa:duncanjdavis/download-monitor-submit
sudo apt-get update
sudo apt-get install download-monitor

NitroShare

NitroShare allows you to easily send files between computers on a local network. Every computer with NitroShare installed will automatically detect every other computer with NitroShare installed, assuming they’re on the same local network. NitroShare also runs on Windows, so you can quickly send files between Windows and Linux systems with it.

Use the application indicator menu, select files and right-click them in the Nautilus file manager, or drag and drop files onto the “share boxes” on your desktop to send them between computers.

Until it’s available in the Ubuntu Software Center, use the following commands to install it:

sudo add-apt-repository ppa:george-edison55/nitroshare
sudo apt-get update
sudo apt-get install nitroshare

Aplomb

Do you waste too much time online when should be working? Aplomb can help by blocking access to unproductive websites for a period of time. There’s no way to unblock the websites from within Aplomb itself — the inconvenience is designed to keep you accountable.

Until it’s available in the Ubuntu Software Center, use the following commands to install it:

sudo add-apt-repository ppa:snwh/aplomb
sudo apt-get update
sudo apt-get install aplomb

Cuckoo

Cuckoo is a simple alarm application application. It can turn your PC into an alarm clock or just remind you to do something. It has customizable alarm sounds and volume levels, but isn’t cluttered with options you’ll never use.

Until it’s available in the Ubuntu Software Center, use the following commands to install it:

sudo add-apt-repository ppa:john.vrbanac/cuckoo
sudo apt-get update
sudo apt-get install cuckoo

TickIt

If you want a simple, old-fashioned desktop application for managing your to-do list, try TickIt. TickIt isn’t integrated with any web service for synchronization, it’s just an application for managing your own task list on your own computer. It’s got filters, deadlines, notes, priorities, and multiple separate workspaces (task lists).

Until it’s available in the Ubuntu Software Center, use the following commands to install it:

sudo add-apt-repository ppa:kazade/tickit
sudo apt-get update
sudo apt-get install tickit

MenuLibre

MenuLibre is a simple menu editor that can create new application shortcuts, as well as edit existing ones. It can also edit the quicklists that appear when you right-click a shortcut on your dock in Unity. In addition to Ubuntu’s default Unity desktop, it also works with Xubuntu’s XFCE desktop and Lubuntu’s LXDE desktop.

Until it’s available in the Ubuntu Software Center, use the following commands to install it:

sudo add-apt-repository ppa:menulibre-dev/devel
sudo apt-get update
sudo apt-get install menulibre
