Rethinking Lemon App's Design System

Introduction to Lemon:

• Lemon Cash is an Argentine fintech founded in 2019.

• Widely popular in LATAM for offering an international prepaid Visa card.

• Offers cashback in bitcoins on purchases.

• Allows users to input Argentine pesos to buy, sell, and hodl cryptos.

• Features a user-friendly interface.

Educative Features:

• Lemon's futuristic and innovative proposition allows users to invest.

• For beginners, the "Earn" section offers tutorials to learn more.

Need for Design System:

• Surprisingly, there's no official publication of its design system.

• Negative reviews on the Google Store point out visual and functional flaws.

• A redesigned system can offer enhanced user experience and value proposition.

Feedback from Users:

• Users have described the app as "childish."

• This feedback underscores the importance of refining the app's illustrations.

• Aim to strike a balance – not too formal, but with a more intuitive color scheme for users.

Operational Changes:

• Proposing a shift from the "Soft Próxima" (Adobe) typography to an open-source option like "Nunito" (Google Fonts).

• This shift will refresh the app's overall communication.

Color Adjustments:

• Current colors offer opportunities for subtle yet functional changes.

• These changes are pivotal for expanding the app's design system.

Layout Considerations:

• Maintain scaling proportions.

• Use a base grid of 8pt with 4 columns and 16pt margins to reorganize content.

• Retain current button designs but adjust colors for better accessibility.

Icon Set Revisions:

• Plan to modify the crypto icon set.

• The goal is to update its visual appearance to harmonize with other design enhancements.

Heuristic Analysis:

• Incorporate heuristic analyses to aid decision-making.

• Ensure a user-centered design approach.

• Iterate the product using a Sprint methodology to reach the most refined version during this case study's development.
