Hi! There is another app i think is called aipolyvision or something like that. I really don’t know how to spell it but you can point your camera on things and it tells you what it is. I don’t know if its good enough to read text on screens. You also have the talking gogles app. /A > 5 juli 2016 kl. 01:25 skrev John G.
