Stickers - AI-Powered Sticker Creations & Community

StreamLine is a popular mobile banking app that enables users to manage their accounts, track expenses, and make transactions. The app, however, was facing usability issues that led to a decline in user satisfaction and engagement. Our goal was to redesign the app, improving its UX/UI to provide a seamless, intuitive, and enjoyable experience for users, ultimately increasing user retention and satisfaction.

From Idea to First Paying Customer in One Week

I was making the AI Backend Proxy + client code for AppKickstarter and making the documentation. I shared to my girlfriend that I can make stickers with the code I provide. We found the idea so fun that I decided to make a very basic app with social features + stickers generation and stickers. I put efforts into making a clean app for the initial AppStore push. And finally got the first paying customer on launch day on App Store.

Process

Research & Analysis: We conducted user interviews, surveys, and analyzed in-app analytics to understand the pain points and user needs. We also studied competitor apps and industry trends to gather insights


Information Architecture: Based on the research findings, we restructured the app's navigation and content, prioritizing features and information according to user needs.


Wireframing & Prototyping: We designed low-fidelity wireframes to visualize the new layout and navigation, iteratively refining them based on user feedback. Afterward, we built a high-fidelity, interactive prototype to test the design.


Usability Testing: We conducted usability tests with a diverse group of users to validate the design and identify areas for improvement. Based on the feedback, we made necessary adjustments to the design.


Visual Design & Style Guide: We developed a cohesive visual language, including color schemes, typography, and iconography, ensuring consistency throughout the app. We also created a style guide to maintain design consistency in future updates.
