Looking great, just a small pet peeve, in the coming soon section, above portuguese you have the brazil flag, feels kinda weird being portuguese and seeing that :)
In that particular case, we chose the Brazilian flag because the list and audio is target at Brazilian Portuguese. We should probably explicitly write "Brazilian."
Interestingly, we couldn't find a flag icon for Arabic that was neutral enough. So we just chose the green color from the Arab League flag (which I guess could itself be controversial) and wrote "Arabic" in white text.
Though, we will be launching Mexican and Canadian soon as well!
