Service Design Project

Lifestyle Tracker App, 夜-Planet


Overview


We designed a mobile app for international students who were forced to return home due to COVID-19 in 2020. Their biggest pain point was sleep deprivation caused by time zone differences, so the app aimed to help them manage their health while staying on top of classes and assignments. To accurately understand their needs, we conducted interviews, observed YouTube vlogs, performed diary studies, and carried out online research.

夜-Planet

Your Healthy At-Home Study Abroad Life Companion
夜 means "night" in Chinese characters, and when combined as 夜-planet in Korean, it conveys the meaning of "Nocturnal."

🦠COVID-19🦠 has disrupted the lives of many international students, preventing them from studying abroad in their host countries. Instead, they are now pursuing their studies online from Korea.
These students attend classes virtually, but they must follow the time zone of the country where they were supposed to study.
This often results in attending classes in the middle of the night, creating significant challenges.

Introducing 夜-Planet(Night Planet)—a solution designed to help those living in Korea but following foreign time zones manage their daily routines efficiently!


Challenges Faced by International Students Forced to Return Home

🕑 Disrupted Daily Routines
Struggling with a chaotic schedule caused by attending live video lectures in the middle of the night due to time zone differences

💊 Deteriorating Health
Facing worsening health conditions as days go by, with some even relying on vitamin injections to keep going

🤦🏻‍♀️ Loss of Motivation
Lacking classmates to study with and spending the semester alone at home, leading to a loss of motivation and constant procrastination


Three Features to Solve These Challenges


01
Sleep and Daily Routine Recommendations

Through a few simple questions, the app suggests healthy lifestyle habits tailored to the user.
Using these habits, along with the user’s inputted class schedule and minimum sleep requirements, the app recommends an optimized sleep and daily routine.
The user can then follow this routine for two weeks to see improvements in their lifestyle.
 

02
Daily Tracking and Self-Reflection

Users can track their adherence to the chosen lifestyle pattern and evaluate how much progress they’ve made over time.

Worried about forgetting to track? No problem!
夜-Planet sends push notifications to remind you to stay on top of your goals.
 

03
Accountability with a Mate

For those who find it hard to stick to routines alone, we’ve added the Mate feature to provide stronger motivation.

A Mate is a partner who helps you stay on track with your routine, and you can invite anyone to join.

If your Mate isn’t following their routine, you can press the "Get It Done!" button. This will make an image of your face float annoyingly across their phone screen in the shape of a sun to nudge them back into action. Once they’re back on track, you can deactivate the "Get It Done!" mode.

Design Question


How can we help students taking foreign university courses from Korea
manage their daily routines effectively?



User Research


Research Question
01
What does your current daily routine look like, including classes, sleep, and waking up?
Are you getting enough sleep? What is your sleep pattern like? How often do you interact with others?

02
What has your experience been like communicating with other students for team projects or assignments?
How is time managed, and how are teams organized?

03
How are you managing your daily routine with the time zone difference?
Are you facing any difficulties? Does the school accommodate the time difference?
04
What are the time management preferences of international students residing in Korea?
05
Are there any other activities outside of classes that you prioritize in your daily life? If so, what are they?
part-time jobs, tutoring, personal study, etc.


Research Methods
Due to COVID-19, we were unable to conduct user research methods like face-to-face interviews or in-person observations. This required us to explore and implement new approaches. We conducted user research using the following four methodologies:

1   Semi-structured Interview

Why this method
Because it allows for more in-depth questions and answers related to personal experiences.

Interviewee 01Hyuk Choi
Returned to Korea during CMU studies
Eastern Time Zone (U.S.)
"My health is definitely suffering because my biorhythm is disrupted, and I feel physically weak."

"I often have headaches and feel completely drained."

"My sleep cycle is completely messed up, which has made me feel really frail."

Interviewee 02Hoon Kim
Accepted to UC Berkeley but had to stay in Korea
Pacific Time Zone (U.S.)
"My sleep pattern is irregular."

"On days with a 1AM class, I can’t make late-night plans or drink with friends. Also, on days with a 7AM meeting, waking up so early can be inconvenient."

Insights
  
  • Even among U.S.-based students, a two-hour difference between the East and West Coast can significantly impact daily routines.
  • Whether a class is pre-recorded or live is a critical factor.
  • Both prefer to maintain a routine aligned as closely as possible to Korean time rather than U.S. time.
  • They struggle with adjusting their schedules due to time zone differences.  
     

2   Vlog Analysis

Why this method
Chosen for its ability to provide real, contextual insights into user behavior and to observe a wider range of users without requiring direct interaction.

A total of 9 YouTubers who are students taking foreign university courses from Korea were selected, and 12 videos were analyzed.

                           
Observation Notes

6AM class - Struggles with extreme drowsiness and finds it exhausting.Laptop time is set to French time.Feels a lack of motivation due to attending classes online.
No real routine, just an endless cycle of eating and sleeping.The issue of accumulated fatigue due to lack of sleep. Can’t sleep at proper times and has very little sleep. Even considering getting vitamin injections.
2AM class - Was too sleepy that she attended from bed, but woke up in the morning to find she had fallen asleep and was left alone in the Zoom meeting.Generally tries to live according to Korean time but often takes short naps or stays up all night due to assignments.

3   Diary Studies

Why this method
To closely examine the daily routines of international students, we aimed to collect detailed records of their daily activities. Due to the challenges of direct observation during the COVID-19 pandemic, we determined that self-documentation would be the most suitable method.

Ra Won Choi
Returned to Korea during studies in Las Vegas
2020.10.30, a day with live class
“For team projects, video calls are scheduled according to U.S. time, and the recorded sessions are submitted. Since I’m the only one in Korea, I have to adjust to the majority’s convenience, which means waking up at dawn or extremely early hours regardless of the time.”
2020.11.02, a day without live class
“In the U.S., daylight saving time usually ends in November. Before, assignments had to be submitted by 4PM Korean time (12AM U.S. time), but after daylight saving time ended, the deadline was pushed back by an hour to 5PM Korean time, which feels much more manageable.”



4   Survey

Why this method
For it is the only quantitative data that can be collected and can produce statistically significant results.


Data Analysis and Insights
Participants’ Common Pain Points

01
Difficulty recognizing time zone differences
While each individual manages to resolve the issues in their own way to some extent, additional effort is required from students to find suitable solutions.

02
Challenges in managing daily life due to time zone differences
Daily routines need to be adjusted to accommodate unique lifestyle patterns, including the need to reschedule appointment times.

03
Difficulty in communication due to time zone differences
It is necessary to adjust communication times with other students to account for time zone differences in academic activities.
04
Challenges of remote classes
There is a need for triggers to motivate academic engagement.

For a Satisfying Study-From-Home Experience :

Users must be able to easily coordinate and organize their schedules without confusion caused by time zone differences. Based on this, they should be able to re-establish a stable daily routine.



Personas

This is a summarized version of the persona. The full version is available on our project’s Notion page. (Korean)

Jaejoon Kim
25, Male

"I never thought life after returning home would be this lonely... I'm slowly becoming a shut-in."

Biography
A 3rd-year undergraduate student majoring in Statistics with a Business minor at UPenn, located in Pennsylvania on the U.S. East Coast.
After returning to Korea for military service, he completed his service and went back to the U.S. However, when COVID-19 escalated and his university went into lockdown, he returned to Korea for a safer environment and has been attending classes remotely ever since.
With an overwhelming amount of assignments and the challenge of time differences, most of his day is spent on classes or coursework. While he used to be socially active and met many friends, his social life has nearly ceased since remote learning began. Furthermore, his lifestyle differs from his family’s, making it difficult to share activities like meals or walks with them.
Having spent his high school and college years in the U.S., he is closest to Korean students studying abroad and stays in touch primarily with Korean friends from high school, even while in Korea.

Goals
Life Goal
  • As always, overcoming challenges together with the people around him.
Experience Goal
  • Amidst his hectic and disrupted routine, he wants to use his "last hours," or spare time, efficiently for social activities.
End Goal
  • Automatically compare schedules with others in different time zones and receive reminders of the little time he can dedicate to them.

Seonrin Jung
23, Female


"Time zones, career plans... everything feels so confusing. 😭"

Biography

A 4th-year undergraduate student majoring in Journalism at UCLA, located in California, U.S.
Due to the worsening COVID-19 situation in the U.S., she returned to Korea at the urging of her concerned family and now attends classes through live video lectures. Coincidentally, all the professors of her registered courses insist on live sessions. With her college friends scattered across different countries, attending classes alone feels even lonelier and harder. Exhausted by the isolation and fatigue, she’s seriously considering taking a leave of absence.
The 16-hour time difference has been a major struggle, as she endures sleepless nights to attend classes. She once tried flipping her daily routine to match LA time but quickly gave up because her light sleeping made it impossible to rest with the household noise during the day. As a result, she often takes short naps whenever possible, leading to a wildly inconsistent sleep schedule.
She often fails to calculate time differences quickly and is forgetful, which has caused her to miss several class sessions and assignment deadlines. So far, she’s missed four classes and one assignment.
After graduation, she plans to pursue graduate studies in the U.S., but with the ongoing COVID-19 situation, that goal seems increasingly difficult. She’s now exploring alternative paths in Korea.

Goals
Life Goal
  • To become someone who can freely do what she loves in life.
Experience Goal
  • To avoid having to manually calculate time zone differences for her often chaotic schedule and ensure nothing gets forgotten.
End Goal
  • To receive comprehensive time management and reminders related to time zone differences.

Takeaways


Designing a service for a user group facing unprecedented challenges during the unique circumstances of COVID-19 was both incredibly challenging and deeply meaningful. With in-person observation and interviews not being an option, I had to actively explore alternative methods to replace traditional user research methodologies. This process taught me the importance of relentlessly striving to understand users, no matter the circumstances, and crafting a service that genuinely addresses their needs.

It was also my first time working on a team project entirely remotely. Spending over 12 hours a day on Zoom in front of a screen was exhausting, but it was incredibly rewarding to see the great results we achieved together. By the end of the project, we even made a promise to each other to bring this app to life with a real launch. This experience reinforced my resilience and teamwork skills, as well as the value of adaptability in challenging environments.
