Okay so saw a few threads on here about these with a few links to the appropriate scanner.
Anyhoooo...... After a couple of glasses I ordered one like in the pic.
It has now arrived and now I have no idea which app to buy. It is the wi-fi one as someone recommended but not even sure what the various apps can show.
I would appreciate any recommendations.
