Yeah I agree, sometimes reading the Arabic words is hard when it is printed really small. I am doing Discussion 1, 3/5 I believe and it tells me to click on the fish. It shows a picture of the fish, so I obviously know the answer, but since I am trying to learn the word for fish, I want to read the actual text below it. The text below the image of the fish, however, is extremely small and hard to see to write down.

bigger and with bigger spaces between words please !!

There's no way I can modify mobile versions but for web version, that is, when you use Duolingo on Firefox or Chrome, I've provided a workaround

I also agree, even using a magnifying glass is difficult to read!
