Nothing like Google Goggles
Google Goggles was absolutely flawless. Regrettably it is no longer available but it was the most incredible research tool that we have ever used.
This one, flying under a false flag of "Goggles", not so much.
The novelty of the speaking app is only worthwhile when it is delivering real information. This app looks at a book cover and returns "book". Show a portrait you want to identify and it returns "hairstyle". Perhaps it is uncharitable to say so but its a pity that there is no way of entering zero stars.
