Currency Widget. Mobile application design.

Design a widget or special application for a Yota smartphone for a monochrome second screen. The widget helps to profitably sell or buy currency. As part of the project, I made the design of the application following the principles of material design, the design of interaction, animation.
How does the app work?
On the first screen, we see the peak values on the chart, as well as the current rate and our target or the price of a profitable transaction. With the usual swipe to the left, you focus on the target’s settings, while you see peak values over a certain period.

Swipe to the right allows you to choose a currency with a minimum amount of effort. Smooth animations between screens give you a feeling of complete control over the widget.
