Hi Mel
I use navagon, ariadne and blind square. All available from the app store. NOt 
free though, sorry.
I use Color Visor which is excellent.
The money readers around don't support New Zealand currency so I don't use one. 
I'm told Look Tell is very good. just search for Looktell and find their money 
reader.

Good luck.
Lisette
