Using on an Audiovox SMT5600. The Task Manager piece of this app is very quick and easy to use. Resco split the Battery/Memory function into a separate Program on the Start Menu. To Close Task, choose Task Manager from the Start menu, then choose the application to close and hit Close Task using the soft key. Can't get any easier than that! The Battery/Memory function shows up in the Start Menu as 'Battery State'. Two screens comprise the program's views: Battery, showing Main and Backup, and the Memory view, showing memory, flash, and Storage card status. The screen for Memory is well designed, and the graphic display is easily understood at a glance. Overall, a very easy to understand presentation of information, and nice addition to any Smartphone.
