Industrial Design Project

Committed is a startup in Austin, TX. Their product adheres to a general framework of mindfulness, acceptance, and commitment to assisting in an individual’s sense of fulfillment. The current service is only available in the Chrome Extension version and needs to improve for a better user experience. 


Committed asked me UX/UI design for their next level of the product. I worked as a UX researcher, product designer, interaction designer, information architect, and strategist for user flow, storyboarding, rapid prototyping, and usability tests with16 participants for 4 weeks.


1 month

  • Client

  • Duration

  • Role

Solo UX/UI designer working with 1 developer/founder

  • Task

User flow, storyboarding, rapid prototyping, visual design, usability tests for developing iOS mobile application


My first step was to identify the business goal, customers, and possible problems with the stakeholder. Then I researched the website (Chrome extension version) and users to gain more insights. After having the needed information, I iterated on 3 rounds of design and finally delivered the project. 



Sep 16 - Oct 18, 2019 (4 weeks)

3 prototype Iterations

In order to build and test many rapid prototypes on a limited schedule, Google Ventures' design sprint process was adopted.

Project defining and planing

- Define problem, set a goal

- Recruiting usability testers

- Plan surveys

- Conduct surveys

- Set schedule for usability tests.

  • 2nd - 4th week (Sep 23 - Oct 18,2019)

- Define problem, set a goal

- Competitors analysis, sketches for solution

- Storyboard of sketches

- Rapid prototype

- Conduct usability test

- Reflection



1. User Survey 

"The service fulfills the need for positive and motivational life with setting daily and weekly goals but have limited convenience of the current service platform."

I surveyed current users among people who actively use Committed Chrome extension version to identify their demographic, frequency of use, positive and negative factors of the current service. Besides, I surveyed 43 potential users who meet the criteria of the target user (23 - 38 yrs, Millennials in the U.S.A, people who are interested in their mindfulness and mental health) set by the company to identify their needs of managing emotions and mind setting.

The survey helped me understand current users and potential users’ behavior and what common habits of their mind management. Those are result of two surveys.

Current Users

  • The most effective feature

50.0% Setting daily reflection

33.3% Setting my daily intention

  • Hindrances of user's happiness / fulfillment 

33.3% Lack of Motivation

  • Need to improve of the current service

66.7% Increase the convenience of the service

(mobile version, edit mode, simplify selecting core value) 

33.3% No notification reminds my daily/weekly goal

Future Users

  • The most helpful method for mindfulness

48.8% Setting and achieving goals

43.9% Getting help from friends

36.6% Reading good articles an quotes

  • Hindrances of user's happiness / fulfillment 

64.3% Anxiety

61.9% Stress

2. Scientific Foundation

"Committed is a suite of digital tools based on decades of scientific research for achieving fulfillment and purpose."

The scientific approach - ACT (Acceptance and commitment therapy) uses mindfulness strategies with commitment and behavior-change strategies, to increase psychological flexibility. ACT intervention led to moderate to significant reductions in general psychological distress, symptoms of depression, and symptoms of anxiety (Yadavaiaet al., 2014, p.256).

3. Effectiveness of the Service

"Committed is a supportive tool via daily practice that causes motivation to fade at a slower rate."

It allows the external motivation of the intervention to become internal motivation. Without Committed motivation fades over time as intervention becomes less relevant because all that motivation came from an outside source, and that source has left.

4. Target Users

"Millennials are so dedicated to practicing mindfulness."

Committed set initial target user as 23 - 38 yrs, Millennials in the U.S.A, people who are interested in their mindfulness and mental health. I deep-dived more information research to identify users' needs, pain points, and possible solutions.. The research shows 64% of millennials say they practice dedicated activities to achieve mindfulness, such as meditation, journaling, or using apps, and it can even help you feel happier by easing stress. Digital technology has helped them on the benefits of mindfulness practice.

5. Market Research

"People are starting to focus on mental wellness,
and it links booming self-care apps."

I studied the existing digital products in the mindfulness market. Self-care apps are booming. Self-care apps topped Apple’s 2018 trends list, as consumers spent $32 million on mindfulness apps. To identify competitors' trend, I've selected mindfulness apps from the best of Apple’s 2018 list and similar apps to the services Committed currently offers. This research shows self-care apps trends that focused on maintaining positive mental health via journaling, setting goals, meditation coaching, quotes and tracking users' trends.

Project Challenge

“How might we develop a mobile application that can users easily set personal goals and reflections to see their positive changes based on daily practice?”

Round 1


1. Design iOS mobile home Screen 

      -- Daily/weekly goal and reflection, quote, core value, dashboard


2. Decide the user flow arriving to the home screen

      -- from weekly/daily goal/reflection to the home screen

User Flow


8 Solution Sketches




1st Prototype

The purpose of the first prototype's usability test was to identify potential users' preference of three different home screen options, and the two ways of reaching the home screen. I try to find a user's preference through a common answer and apply them to the second prototype development.


Four people - Sarah Stumme, Yuling Yu, Andrew Kwak, and Josh Kim- participated in the first usability test on Sep 26th to Sep 28th, 2019. All participants live in the U.S.A, and their age range is between 23 to 38 years old.

Round 2


1. Design OnBoarding page

      -- Introduction of Committed service


2. Revamp choosing core values

3.Develop the home screen based on users' feedback


8 Solution Sketches




2nd Prototype

I conducted the second prototype's usability test on October 3rd and 4th, 2019 with six users: three existing users (John Fitch, Joshua Olszewski, Hunter Monk) and three future users who have never used Committed (Jordyn Stanek, Keren Weiliu, Yoshie Ejaz).


The usability test focused on to identify these three things;

  •  Does the onboarding page explain this service well?

  •  Any difficulties or confusion using daily/weekly goals & reflections page and home screen. 

  • Suggestions for improvement.


Round 3


1. Design all weekly/daily goal and reflection pages

2. Redesign the home screen based on the last users' feedback


3rd Prototype

The 3rd usability test was conducted on October 10th and 11th 2019 with six participants (Yiran park, Byan Brashearmiller, Christian Casadio, Jane, Alex, Jessica Nam) via video call.


The 3rd usability test focused on to identify followings;

  • Examine the ease of use of the weekly, daily goal/reflection page, home screen, and report page.

Participants wouldn't feel difficult for using apps, but they advised some minor modifications.

Insights & Moving Forward 

1. Communication is important. 

This project proceeded remotely, so interactive communication has brought a lot of efficiencies. I shared every process via Google shared documents, and the company was able to share comments on each document. This open communication process has helped to increase mutual trust. By increasing the confidence of the designer and the company and exchanging ideas with each other, we were able to focus on reducing errors and finally achieved desired goals.

2. In-depth research should be conducted before high-fidelity

If I have another four-week project similar to this next time, I'll invest one more week on UX research and do prototypes for two weeks. I satisfied with the three high fidelity outputs and the three usability tests, but it was sorry that the limited time for research.

 3. Be ready contingencies on usability tests.

A UX designer should anticipate all possible unexpected situations during usability tests. Before a test to the participants, It may be a good idea to remind the test time and tell them to find a quiet place when they make a video call. I also learned that it was essential to have enough time between a tester and the next tester when scheduling.
