I bought this 7-1 translation app while in Mexico when prompted by its companion app.
With this app supposedly you can take a picture of Spanish text (like a road sign or instructions printed on a product you might buy in a store) & the app will OCR the text (that is, recognize the words in the picture as text) and translate it. Barely!
I found the app useless. First, it would not OCR the text well. Second, its translations were ridiculous, mostly wrong (not slightly wrong, really wrong) and ultimately useless.
The concept is great: an app that will translate foreign text into English. Awesome. This app does not do that, it pretends to do that.
As you tell, I am very disappointed with this app, particularly having such high hopes.
(As a side note, I compared this apps translation with some on-line translation engines. No comparison. The on-line translations were correct, this apps translations were misleading or useless.)
Be forewarned.
