Helmut app
Vocabulary app for students of German language.
My role > UX Designer & Researcher
Overview & Objective
Helmut app is a mobile app for students of German which provides instant vocabulary translations that could be stored in the form of flashcards for later practise.
Users needed an easy way to look up the meaning of new words on the go, being able to quickly get the right context and to retain the term. The goal was to provide graphical and memorable examples of the terms, that could be easily stored in the form of flashcards and practised later.

Context & Purpose
UX & research project on the initial phase of my UX Design certification, for learning the main concepts of UX design before facing the deeper phases of the program.
Market Research
I learnt about my competitors in the market of vocabulary apps.
User interviews & Personas
I conducted user interviews with 3 people within my user target to know which were their behaviours as well as their needs and goals while learning German vocabulary.
After that I processed their answers on a table with doing/thinking/feeling columns. Once I grouped and prioritised their quotes I was able to get clear insights for creating a proto-persona
User stories & Problem statement
I created some user stories for my proto-persona and selected the most relevant. Those were the base for my Problem statement and Hypothesis.
User flows
I defined user flows for some of the user stories.
Wireframing & Prototyping
Later on, I drew up wireframes using pen/pencil.
With the goal of testing my flows as soon as possible, I generated a quick prototype using Marvel app and the paper wireframes.
Usability Tests & Learnings
I conducted 3 in-person usability tests to get direct feedback from the users and spot the pain-points of my prototype. The tests included 4 tasks.
I organized my notes trying to find common issues and prioritized them using Jakob Nielsen’s error severity rating scale. On the images below you could see a before/after changes of the low fidelity prototype and the suggested next steps.
