Easy Blue

I need a mobile application similar to a Wertern Union, but simpler. I need all the welcome interface, user registration (profile), and a screen that shows the option to send the money at the same time, to see the conversion and how much you will receive, so I need a screen where the customer can see my data to carry out the transfer and finally send me the attached receipt. Not to mention all the other features such as transaction history, coupons, contact us, among others. The app only works on one currency pair, which is BRL/ARS. I need it urgently. Thanks for listening!
