I am Arabic person, I come up on your app, to be honest I like and I did not have the money to buy it, little I know your application is free. I feel shamed to what I was going to do. but I will make promise as this is your investment in me. once i make money out of it, definitely I will donate to you. but in the meantime, I could offer my service to you. for translating your content into Arabic language. ( the community is big). send me your application/website files. I will happily translate it for free to you as payback for now for the application. 

Abdullah,

Best regards
