It's really so good that the app supports Persian... ( We learned English to be able to use these apps, but some people can't afford to pay English classes And your app will really help them! ) It's really Interesting that the pro version is free for us... It's really awesome because we can't shop from Foreign countris easily. Thank you so much! Wish you all the bests!
