SuperBox is free today as part of the Free App A Day promotion through Amazon's Appstore for Android.
This app brings forward a lot of features that are already on your Android device, though a few clicks into you Settings menu. SuperBox does not really bring anything unique or empowering to you phone and a lot of reviewers are expressing that.
For example, SuperBox allows you to check your battery details. You can already to this from Settings>About Phone>Battery Use. This will tell you what has been taxing your battery and help you to understand if any apps are overusing or if its just how you are using your apps.
Another popular example is clearing the cache. Though this is not something you'll want to do to apps you use everyday, it is possible from Settings>Applications>Manage applications. Notice a "Running" tab among the others. Use these tabs to see what you have installed or are currently running, then click an app and you may have the option to Clear Cache. Warning: DO NOT select Clear data!!!
Make sure you are not clearing your data unless you intend to re-enter the information needed for the app to operate for you. In other words, if you clear the data for 100 Pushups, you will lose all previous pushup records you've ever saved. If you clear the data for any game, you'll have to start the game over again. If you clear the data for Qriocity, you'll need to re-enter your account info or possibly reactivate the device.
It is with this app that you may be able to do all these things and more from the confines of one app rather than scattered all over the Settings menu. Though do be cautious with apps like this that promote clearing caches and killing apps. As I've said before and many others have documented, killing apps is not actually doing any good on Android 2.2 or greater. The apps are simply restarted because they weren't actually running in the first place.
