I decided to utilize the font pairing Nunito and Source Sans Pro because these fonts create a harmonious aesthetic, blending modern lines with soft, rounded edges. They prioritize readability and clarity, ensuring users can easily navigate the app without strain. Additionally, Nunito and Source Sans Pro are versatile, adapting well to different screen sizes and resolutions for a consistent user experience. Their clean appearance conveys professionalism and trustworthiness, crucial for a travel app where users rely on accurate information. The combination also establishes a distinctive content hierarchy, with Nunito for headings and Source Sans Pro for body text.
