After reviewing several app rating guidance documents and tools , we concluded that each app has its own uniqueness for particular categories of application . We took into consideration prior studies on software quality assessment , and emphasized the key software quality characteristics such as usability , reliability , functionality , and efficiency [ 14-17 ] .

This rating tool consists of modifications that we hypothesized to be more important for a foot measuring app . FootMARS considers
