I bought this application off the market and it does everything that it says that it would do in the application info. It is very useful for speeding up your phone or ending another application that is not working. It also is great for telling which applications are mainly hogging up your memory and or checking which applications are running down your battery. It is very easy to end an application, all you do is click the ones that you want to be killed and then click the button that kills them and your done. I highly recommend this app especially for its cheap price its definitely worth it and will help your phone.
