Thanks, I am pleased to know I said something useful! Actually, it is quite an achievement to develop an application and release it, and it is certainly leading-edge for ASSI to be doing it.
One other suggestion, although certainly minor. When selecting an image I didn't appear to have an option to take a photo but rather to browse for an existing image,
From a usability point of view this may present some barriers. The user may not wish to bother taking a picture, running the app, returning to the home screen, taking another picture, running the app again, etc.
Or, they may take several photos then run the app but then not be certain which is which.
If it is possible, the option to take a new photo as well as browse at the point of selecting sn image could be a useful addition.
