Android assistant can be downloaded for free from the market. it is an application that will do works for lots of applications. It has 18 features in it. and we don't have to install 18 apps for that only 1 will look after all. and this is the one. The size of app is also not much ( it varies from device to device ). The application is easy to use. we can backup our apk files and reinstall them when ever we want. we can also move our apps from phone to memoery card. we can manage phone ringtone and volume also from this app . there is widget available which ease our work more. we just have to touch and work is done. It also has a power saver . it cleans cache files which will make your phone work more faster and smooth. It will also show montior status , CPU status , RAM , ROM, Memory card . which will help in managing applications easily, and we can see when our phone gets over loaded. I have tried all features personally and each and every feature is working perfectly. there is no problem in this app. All 18 features are as good as they say . Go for it.
