Style Guide

Poppins is a popular design tool for creating geometric sans-serif mobile apps. Its precisely crafted geometric letterforms make it ideal for both headings and body text.

Blue is highly comfortable, evokes a sense of security, and builds trust in the product. It is also often associated with depth and stability. For the app, I chose blue as the primary color, complemented by dark blue and gray as secondary colors to create accents, while black and gray were used for text. This combination of colors helped establish a clear visual hierarchy of information.



The component library was created to facilitate the interaction between designers and developers and preserve the visual concept of the application.
