The Google URL Shortener employs the card UI that is becoming a Google trademark. The app is optimized for Android flavored smartphones and 7 inch and 10 inch tablets and allows you to shorten links using "share" in any app. You don't even have to be online to access your data.
The app is free from the Google Play Store and requires the user to have a device powered by Android 4.0 or higher.
