Redesign Uniqlo's iOS App

UX Case Study

Overview

Uniqlo is a Japanese clothing retailer and manufacturer reknown for its affordable and comfortable product line. Ever since I came to Canada, I have been very fond of their clothings. I am usually Uniqlo's in-store shopper. But since the pandemic hits, I have been avoiding all in-store visit and switched to online shopping . Couple of months ago, I tried to use Uniqlo's iOS app for the first time to order some activewear. As a user, I found the user interface difficult to navigate and as a designer , I found many flaws. To soothe my designer soul, I wanted to dig deeper and take the opportunity to redesign the user interface.

Objective

The project is unsolicited and the goal is to identify any usability issues and redesign a better user experience for Uniqlo's iOS app.

I completed the redesign process based on the findings of the following questions:

  • What are the key usability issues of using the user interface of Uniqlo's iOS app?
  • What is the mental model of clothing–retailer–app users?
  • What are the necessary features missing in Uniqlo's iOS app that might have an impact on it's user experience?

Based on the insights, the project's goal led to designing a functional prototype.

The Process

I divided the redesign into three phases:

User Research

Usability Testing

I conducted usability test with 5 people and asked them to perform few predefined tasks in the iOS app.

I mainly approached my friends and families. Since it was a lockdown due to Covid-19 pandemic, I took the interview using facebook messenger, used it's video chat and screen share facility to monitor participants' actions, recorded our conversation in voice recorder and took notes with pen and paper.

Some of the tasks/questions were:

  • What are the tasks you usually perform when you use a clothing retailer's app?
  • What do you want to see first as you open the app?
  • Browse and add a product of your choice in your cart.
  • Find out what's on sale ,new arrivals, store location, your order history, and size chart.
  • Change notification settings.
  • Check if you have a discount/coupon.

This is what users said during the usability tests:

  • Why everything is so clumpsy?
  • There are so many things. I am lost!
  • I can't see these texts.
  • Where is my account?

Identifying the Problem

Participants particularly faced the following difficulties:

  • Navigation through "Home" tab.
  • Browsing product categories.
  • Finding "Order History" and "Size Chart".

Analyzing Current App Structure

Since most of the participants including myself had difficulty in navigation, I built its information architecture to better understand its structure.

Competitive Analysis

I looked into the app of leading Canadian clothing retails who have good rating on app store (above 4.6) and good reviews about their UI. I went through their information architecture to see how they have organized their app, and what are the features missing in current Uniqlo's app.

The Redesign

Revised Information Architecture

The designed the new information architecture to increase the visibility of the app’s key features and improves the overall organization and navigation throughout the app.

Ideation & Prototyping

Before committing to high fidelity designs, I sketched out possible solutions on paper for the main screens.

UX Suggestions & Redesign

1. Rearrange the Tab Bar

Currently, there is 4 tabs in the tab bar i.e. "Home", "Wishlist", "Scan" and "Membership" which I have rearranged following ways for better user experience.

  • I added 2 new tabs i.e. "Shop", "More";
  • Users were confused with the tab name of "Membership". So, I changed it to "Profile";
  • I relocated "Scan" icon from the tab bar to the top, just above the search bar for the following reason:
    • I wanted to make room for more important use cases in the tab bar;
    • It makes more sense, if scan and search bar is close to each other;

2. Change Layout of "Home"

Currently, the "Home" tab looks cluttered and messy. During the usability test,users seemed lost while they were navigating through home page. So, I changed its entire layout to give it a cleaner look.

3. Add "Shop" Tab

In current app structure, if users want to browse products there are two options available. One, they have to search the product category in search bar on the top. Two, they have to scroll down to find out the categories. As per my analysis, including all sub-categories i.e. outwear, tops, bottoms in the "Home" tab is making the UI more cluttered. So, I added a new tab named "Shop" in the tab bar and relocated all sub-categories there so that users have easier, cleaner and quick access to the product categories.

Also, I made the following changes in the subcategories:

  • Moved Sale, New Arrival to the top
  • Added two subcategories i.e. "Bestseller", "Clearance"

4. From "Membership" to Profile

  • During usability test, participants were confused with the name "Membership". As per their mental model, participants were looking for "account/profile" when they were asked to perform some use cases such as change your address, see your order history, check if your have a coupon. So, I changed the icon name to "Profile"
  • As per the current app structure, a user has to click the cart/ add something to the cart to get into the log in/sign up page. Otherwise, there is no direct access to log in/ sign up. So, I added "Sign In" and "Create An Account" button in "Profile"
  • Participants had difficulty distiguishing between "Order History" and "Purchase History" as they mentioned both of them sounds similar to them. So, I changed the name to "Online Orders" and "In-store Shopping"

5. Add "More" Tab

I added a new icon in tab bar named "More. Whereas "Profile" icon is all about a user information, "More" icon is all about Uniqlo's information and getting connected with it.As per my analysis, the current app structure falls behind in providing information about helping/ supporting users.

  • I noticed there is no information available about their customer care. So, I included a "Contact Us" option.
  • The other information for help and support such as "FAQ" is in "Membership" tab, which was time consuming to find. So, I moved those under "More" tab so that all information source for helping users are grouped together.
  • Though available in web version, there is no information about Uniqlo's social media account.For better exposure, I included "Follow Us" option.

Functional Prototyping

I used Invision to create a functional prototype of all the screens. Check it out here.

Validation Testing

To validate the changes I made, I tested the prototype with 3 participants (1/3 participants were same who participated in first usability test). I asked the same questions from my initial tests and recorded their behavior and feedback.

The Results

As a result of the redesign, the success rate for tasks increased to 100% for all use cases except 1 participants had difficulty browsing product categories in "Shop" tab. Some comments were:

Though the "Shop" tab was visually pleasant, after the validation testing I felt there is still opprtunity to optimize the content. So, I made a separate sub-category named "Featured Item" and included "Airism", "Heattech", "Fleece", "3D Knit", "UV Protection", "Special Collaboration" under this sub-category. Here is the glimpse of final version of information architecture.

Reflection on My Work

There is a saying -“If you love what you do, you’ll never work a day in your life.” After completing the project, I understood the true meaning of this sentence. Redesigining the app was huge amount of work. But I enjoyed every bit of it. And all hard work paid off when I heard the participants in testing phase saying how much they have liked the new design.
