What Was the Problem?

What Was the Problem?

At that time, Fluency Academy was looking to modernize the visual concept of all its products, aiming for a more fluid, relaxed, and welcoming appearance while maintaining its casual vibe with vibrant colors and elements that inspired students to learn.

We began with Memhack, which was the largest and main digital product of Fluency at that time, reaching more than 500k users. We seized the chance to enhance the app's appearance, as you'll notice. Overall, the user experience has been significantly improved.

Changes That Made a Difference

Changes That Made a Difference

Often, less is more. The statistics section that appeared on the dashboard when students logged into the app was found to be largely irrelevant according to research conducted by the Customer Success team. Additionally, some statistics were repeated at the end of the study session.

This allowed us to transform the dashboard into a library that automatically filtered and displayed the content students needed to study at that moment, while we kept the statistics only after the session or in deck details if accessed.

Minimalist Study Session

Minimalist Study Session

The study session is by far the most important feature of Memhack. Students can easily spend an hour reviewing content in a study session. That's why it has been given a more neutral, clean look that is less tiring and has more personality.

Rating your performance on each card is crucial for memorization in this app, as it calibrates the SRS and decides when to review content. Adding personality and enjoyment when clicking on a note has significantly improved the student experience.

Recreating a Design System

Recreating a Design System

Constantly collaborating with the rest of Memhack’s team, the design system was created consistently, well-organized, and tailored for Flutter, the technology used for both the app and the web version.

Having designed various features for Memhack over the years, the Design System has been modified numerous times, becoming robust while always maintaining simplicity and efficiency in each component.

Every decision was data-driven. Constantly in touch with directors, I also collaborated with the Customer Success team, Developers and QA through daily build reviews to ensure functional, intuitive designs. Navigation and interactive elements were streamlined for clarity.

To cover a wide range of study contexts and support the mission of democratizing education, Memhack has also been designed as a responsive web version that considers not only the dimensions of elements but also the usability differences across various devices.

As mentioned above, students can spend a significant amount of time using Memhack, and it was essential to adapt it for all study contexts. The dark mode was not just about aesthetics; it was a necessity to minimize strain on the eyes of those studying in dark environments.

During my years as the lead designer for Memhack, we also created a landing page to guide new students on how to use the application alongside their classes, as well as the main access page for Memhack's web version.

Conclusion

Conclusion

Leading the redesign of Memhack as part of Fluency was a wonderful and rewarding challenge. From creating basic app elements to adding specific animations to enhance the student experience, my team and I significantly improved the journey for those looking to change their lives by learning a new language.

This was one of my first efforts at Memhack, which allowed us to build a solid foundation for many other features I developed with my colleagues in the future, such as adding gamification through streaks, voice recognition for pronunciation practice, and onboarding new students, among others.
