Learnability
Most of the options of this design are derived from existing designs of many common smartphone menus. Taking a picture of a receipt and browsing through old receipts is similar to the iPhone's camera interface, and entering and editing receipt and report details are similar to its settings menu. This aspect of the design makes it very learnable for smartphone users. The other elements that do not have a parallel in common menus or applications are sufficiently documented, with the buttons stating exactly which action should be taken. One aspect in which the user will have trouble learning the interface is navigating between the different screens. It is not always clear which button will lead to which screen and which receipt/report the user is currently looking at.
