XPay is an application with which the user can convert currency and perform various financial transactions. Financial operations include the functions of sending, requesting, earning and credit funds. Plus, this application analyzes the user\'s transactions and provides information about the transactions performed. An important feature of the application is that when sending funds to any person, we can indicate the area of his costs.We redesigned the existing MVP app, made it a “selling” and fixed various UX flaws.In the process of work, we created several options for the color scheme for the application and provided the customer with a choice. Based on this, we managed to implement a juicy and bright design that will attract the eye of any user.
