This app is too simple to the point that it looks like a book. The apperance is too simple that it looks like it was made by a novice who had no background in artistic visualization. In short, this app could have been better and is not user friendly. There is no difference in changing from one transaction to another. Also why do you have multiple apps instead of one app with all of the needed functionality. Very questionable for the user, as it confuses which one is the one we need.
