App now works
Low ratings seem to be from a previous update. As I write this the app works well: it walks you through the process of setting things up- some grammatical mistakes indicate that the developer is not a native English speaker, but the intent and instructions are clear.
Detecting and changing the wifi password and name is easy. The loading time for pictures is somewhat slow, but that may be a limitation of the technology.
