Go to the Apps Marketplace at https://apps.google.com/marketplace.
Sign in with your Google account.
At the top of the page, click Manage Apps.
You'll see a list of administrator-installed apps (if you're using Apps in an administered domain such as a business or school) and any apps you’ve installed yourself.
To remove an app you installed, click Manage > Remove.
To share a link, click and either email the app link or share via Google+
