CaptchaToGo is a free, easy-to-use app that helps you to solve captchas on your smartphone. It's a plugin for JDownloader and some other downloaders, and it works in a very simple way.

It offers you a possibility to download files from a website, which is not so easy as it might seem. The first thing you have to do is to enter a code, which is unique to your smartphone. The code is displayed on a screen and you have to enter it manually. It is not a very secure way to download files, but it is a lot easier than typing the password.
