What is Vocab?

VOCAB is a mobile application that helps the users to learn a new language by using a systematic guidance and well-designed instructions to acquire writing and speaking competence.

The Challenge

Learning a language can sometimes be a challenging and frustrating experience. The effective memorizing is one of the most important issues in a foreign language environment. When learning a new language, there are always many obstacles and challenges that we need to overcome in order to reach a good level.

Our solution

By creating a meaningful and a motivational experience will give the feel of a big challenge in learning the new language. It takes a gamification approach to education, attempting to make study and practice more engaging than an usual vocabulary app. Learning will not happen unless the brain actually decides, “I need — and want — to know this.” Based on Ebbinghaus’s Forgetting Curve shown below, it’s easy to know that at the first 24–48 hours after learning, users’ knowledge learning has a slump. With time goes, the knowledge retain keeps a flat rate.The brain seeks meaning and works to connect with new information. Once this happens, the language not only has meaning, but it actually begins to matter, as the user will find himself personally invested — intrinsically motivated — in his study.

The Design Process

The Competitive Analysis

I focused on how easy the apps were to use and whether the features successfully accomplished the goals of the users. I thought carefully about how I felt using each app and what I might do to make the experience better.

The User Persona

I created a proto-persona and restated my project brief using user stories, a problem statement, and a hypothesis statement for building a new language learning app.

The Information Arhitecture

After understading our user persona’s problem we were able to develop the tasks analysis and which led to the creationof the following information arhitecture. It offered us the view in which a user will complete a specific task.

The Wireframes

After that, we begun the wireframing process. Here we were able to write the first sketches, developing the hierarchy, the buttons and the functions, beginning with the first interface of the application, going through the onboarding and registering process and the most important step for our application, as learning the first word. We’ve tried to develop an easily accessing solution in order to give the best results in user’s satisfaction.

The Usability Testing

Once the prototype was ready for testing, I run the usability testing together with 3 participants to gather all the inconvinients and to find the improvement solutions. I've tried to manage their requests into implementing a number of possible application improvements.

Then, the final form of VOCAB app took shape.

Future Steps

This project is still work in progress. I'm planning to conduct more usability tests since click tests are quick and always great for speeding up the decision-making process with very little investment.


The VOCAB app gave me experience with every aspect of the UX design process, from initial research to high-fidelity mock-ups. I learned how to translate the user needs into an useful and successful design. This was my first UX project and I found it a lot of fun. It helped me to develop both an understanding of the key principles of UX processes, as well as how to use industry tools, like Adobe.
