Yes Nik, I agree - and I was willing to support their idea and invest in the App, as it may save me learning Spanish when our proposed trip to do the Camino de Santiago comes to fruition. Here's some illustrations of how it currently works. It only does literal word for word translations at present, but good enough to read signage and save flicking through dictionaries. Amazing potential in this idea!
