Safe Links is a URL scanner that checks all the links you open on your mobile for malicious sites that aim to harm you or your phone. It also expands shortened links automatically so that you can see exactly where you are going after you scan a QR code or click on a shortened link from Twitter.
It works from all apps including Twitter and Facebook, as well as links scanned in QR codes. You just need to set it as your default browser when prompted.
If you find a link shortening service that it can't resolve or doesn't scan, flick me a comment with the url you clicked on.
