RESEARCH
Competitive analysis
I performed an in-depth study of two competitors to understand the market, key objectives, overall strategy, and advantages, evaluating usability, strengths, weaknesses, opportunities, and threats.
User interviews
I recruited potential users to participate in interviews conducted by me. They answered questions that aimed to understand user behavior around digital money transaction platforms and online shopping.
Card Sorting
Aiming to improve the site map and adjust the placement of features to the user's needs, I asked 11 participants to sort 20 cards into groups, utilizing Optimal Workshop.
Usability testing
To evaluate the prototype, I conducted Usability Tests (plan, script, and analysis) with 5 participants to observe and measure their interaction with the app, analysing behaviour, feelings, and actions when performing the given tasks.

INSIGHTS
USER INTERVIEWS
Based on the affinity map, we generated the following insights by grouping similar notes under similar headings.
With that, we found out that the users are…
INSIGHT 1
…using applications to make payments more than to request payments;
INSIGHT 2
…concerned about privacy, data and security;
INSIGHT 3
…expecting quick transactions with a confirmation message when completed;
CARD SORTING
From Card Sorting, I discovered that the users…
Before
INSIGHT 4
…understand more effectively the term "payment" rather than transactions;
INSIGHT 5
…assume that "account" and "transactions" belong to the same group, which they called “services";
INSIGHT 6
…acknowledge three categories: settings, security, and services;
USABILITY TEST
The Usability Testing results show that the users …
INSIGHT 7
…expect clear guidance from the app when performing a transaction;
INSIGHT 8
…find the link to be sent to share payments with friends an advantage;
INSIGHT 9
…need to see familiar or intuitive feature names to be able to recognize functionalities in the app;
DESIGN
Design best practices
My journey in building the Wise-wallet app can be summarized as a constant search for the best placement of the elements on the screens. I discovered that the correct usage of white space, grid, alignment, and colors, creates a polished user-friendly interface that is easy to read, understand, and navigate.
My design decisions are based on Design and Navigation Patterns, and Visual Design Principles to achieve a clean and aesthetically pleasant interface.
I gathered feedback on my design through expert evaluation provided by my mentor and my tutor, as well as from friends during the Usability Test.
Accessibility guidelines
Wise-wallet aims adequacy to accessibility guidelines, as a way of building a more inclusive interface that can be navigated by people with different disabilities.
Following Web Content Accessibility Guidelines, I decided to improve the visual presentation of the form fields with placeholders; and the icons in the bottom navigation bar with labels.
I also chose recognizable symbols, and icons, to apply to the interface, but the biggest change was in the color contrast.
As shown below, the contrast ratio is improved to 16.61:1, and an AAA accessibility level is present, which is in agreement with the guidelines.
Data-driven Design
During Usability testing, users had trouble understanding how the image carousel works, claiming that the arrow was too small or trying to move to the net screen by dragging instead of clicking on the arrow placed.
I decided to run a Preference test to make the Onboarding flow less confusing. I recruited 12 participants and asked them to choose one of the two options presented below, containing different ways of screen transition.
As a result, 09 of 12 participants chose the screens with the "Continue” button and the "Dismiss” option straight below, claiming that it gave them more guidance on what to do.
Option 1
75% votes
Usability Heuristics
The “Request Money” flow was a great opportunity to design an interface that applies some of Jakob Nielsen's principles for interaction design and usability attributes.
The new flow presents more Efficiency and Learnability, as well as, gives Visibility of the system status and User Control and Freedom, reducing the user’s cognitive load.
