User Journey Map of Lee

Paper Wireframe

I took some time to draft an iteration of how the main page would look on paper.

By comparing each design, I highlighted some preferred elements with stars that are commonly created in my drafts. For example, a top navigation bar, grids, and a horizontal scrolling menu.

From Paper to Digital

In the initial phase of design, I first brought my design to Figma and made sure all basic and vital elements are added.

After the main user flow was created, I recruited 5 potential users to conduct the usability study and collected feedback.

Usability Study

I conducted two rounds of usability studies. Findings from the first round helped guide the design from wireframes to mockups. The second usability study used a hi-fi prototype and revealed what aspects of the design needed refining.

Round 1 findings
  1. Users were confused about the food tracker position
  2. Most users did not understand the grocery feature
  3. Reflected in a “so-so” attitude
Round 2 findings
  1. Images of groceries should directly lead people to the item detail
  2. “Now we need” circle made confusion with the food tracker
  3. Consistency of the app needs improvement

Before & After

Iteration #1

Before the usability study, the main goal of the meal description page was to make every dish photo and description clear.

However, based on user feedback, I adjusted the page to a pop-up page so that users can easily continue shopping.

Iteration #2

I designed the grocery page as a reference page where users type in the items they need before the usability study.

During the study, most users found it confusing. Therefore, I re-designed it to a more user-friendly and visually appealing page.


The hi-fi prototype consists of more interactive elements and animation between pages. 

It also iterated feedback from the previous usability studies.

Sticker Sheet

Warm colors and rounded shapes convey comfortable feelings to users of Ichiban’s app. We wish our users could feel relaxed and less anxious while using the app and prepare themselves for a nice meal. Color of yellow, light yellow, and cream brown gives a natural and calming feeling, which is used throughout the app.

The main typeface of choice is Jaldi. We choose a sans-serif typeface with rounded edges, in order to keep the consistency of comfortable and relaxing vibes in the app. 

High-Fidelity Prototype


"It's clear and easy to use!"
"I could imagine myself using app like this"

What I learned:

During the designing process, I understand the job of a UX designer is to make the users’ needs into something real. Therefore, it is crucial to put users at the front while designing at all times. Usability studies and feedback are great opportunities for designers to reflect if they understand users’ needs and time to make improvements.

What's Next

  1. Conduct the 3rd round of usability study with users from different age groups. In order to understand the needs and pain points of users of different ages.

  2. Conduct competitive analysis to understand the trendy features to make Ichiban’s app more competitive.
  3. Browse Dribbble or Medium to know the trendy visual design of apps nowadays to make Ichiban’s app more visually appealing.
