A lot of apps have been written to help people improve their typing skills. The difference between Key Hero and the other applications is that it's an online free solution. You won't have to install a thing. You just need any web browser and flash player to start improving your typing skills. Another important feature of the site is all the performance stats. When you are a registered user, you can view a chart of your typing tests and see how you are improving. You can also see your accuracy and how you have progressed.
