About

A financial crypto service for beginners. A mobile app for buying, exchanging, investing, and making payments.

Task

Development of a multifunctional crypto application for iOS and Android with a bold, vibrant design and a clean, user-friendly interface — an app that combines the functionality of the previously developed Lynx and Must apps. Additionally, the creation of a landing page for promotion.

Stages

  1. Gathering requirements from stakeholders (briefing)

  2. Research and analysis (study the market and understand project constraints) - examining our product, competitors, and limitations

  3. Developing user flow

  4. Wireframing

  5. Developing a UI kit and design system

  6. Creating the style: defining color palette, typography, icons, and other visual elements

  7. Designing

  8. Animated functional prototype

  9. Handover to development

  10. Design review with task assignment to developers

  11. Creating the landing page

  12. Launch and support (developing new flows, adapting old ones to new requirements, improvements to the design system)

User Flow

At the initial stage, my design team and I prepared the user flow, which allowed us to establish a logical sequence of screens and actions, solidify the application's core functionality, and ensure that all features are easily accessible and understandable

Wireframing

During the wireframing stage, the team discussed and agreed on the elements and their placement on the main screens. I designed all the screens related to the bank card flow.

UI-kit

The UI kit consisted of 400 components and 32 styles at the start of the app development. During the application's development, the number of components increased to 792.

Prototype

The flow of card issuance and usage

Part of the flow

The result, using the flows I developed as an example: the user's path from the main screen to cryptocurrency exchange and card top-up

Landing page

I designed a landing page for promoting the finished product 

Results and Business Impact

  • User Base Growth: After launch, WeWallet attracted over 6 000 users in the first six months and 4 000 in the next four months

  • Conversion Rate Increase: The optimized user flow improved the registration conversion rate by 25%, reducing drop-offs during the verification process. Previous company apps (Lynx, Must) had lower conversion rates due to friction in this step, which we successfully addressed in this version.

  • Development Speed: Implementing a 742-component design system accelerated interface development, reducing the average time needed to create new screens by 40%.

  • Landing Page Effectiveness: The newly designed promo landing page increased ad campaign CTR (click-through rate) by 22%, leading to an 18% decrease in user acquisition costs (CPA).

  • Simplified Crypto Transactions: The intuitive interface reduced support requests related to deposits and withdrawals by 27%.

    As a result, WeWallet’s design not only enhanced user experience but also drove growth in key business metrics, directly contributing to the app’s success.
