I'm a native Arabic speaker, and if I see that word "جودي" anywhere I would pronounce it exactly how "Judy" is pronounced in English.
Again, slightly inaccurate pronunciation, which I'm sure will be fixed with later revisions.
Overall, great work so far.
I use the mobile browser version and zoom in/out to read all the time. It has its drawbacks though. In "what sound does this make" exercises the audio button falls exactly on the word, covering half of it. I got rid of the app a long time ago.
