Research
Understanding the loneliness problem.

Loneliness is a new epidemic and it's killing Americans like smoking 15 cigarettes a day
Lack of social connection is deeply tied to both physical and mental well-being. It increases the risk of early death by 26%, which is comparable to smoking 15 cigarettes a day, according to the U.S. Surgeon Journal.
Young adults are the loneliest age group, 2 times more than seniors
The rate of loneliness among young adults has increased every year between 1976 and 2019.
While the highest rates of social isolation are found among older adults, young adults are almost twice as likely to report feeling lonely than those over 65.

The hard truth
Welcome to adulthood,
your friendships are no longer the same.
The thing about adult friendship is that it went from a group activity to an individual sport.
— Mel Robbins, best selling author and speaker

The infamous "Great Scatterings"
The Great Scattering happens during the period in your 20s when you graduate, leave school, and suddenly realize that all the people who once lived in the same place and move in the same timeline as you now scattered in a million different directions.

Research from both MIT and Stanford show that proximity is the single biggest factor in determining friendships.
A 2021 University of Kansas study found that it takes around 200 hours of intentional time together to form a close friendship.
Yet few tools exist to help people track, reflect on, or commit to that time investment.

Design Feature 1
Home Screen Check-in Reminder
User goal
Get timely reminders to reconnect with friends, view personalized activity suggestions based on past interactions, and take immediate action to reach out.
Exploration
I explored different home page layouts to see which one feels the most intuitive and support quick decision making to reach out to friends.
V1 Single Card Layout
One friend per screen, scrollable interaction

V2 Grid Layout
Quick scanning across friends, with action menu

V3 Stacked List
Swipe-able actions and quick check off


I ultimately chose Version 3 for its flexibility, scalability, and support for quick, intuitive interactions. Unlike the grid layout, which can feel visually unbalanced with an odd number of cards, the stacked list adapts well to varying amounts of content. It also enables swipe gestures for actions like snoozing or skipping, offering more depth than a simple check-off experience.
Design Feature 2
Personal Notes & Hangout Log
User goal
To quickly jot down notes about their friends or create a hangout log.



Design Feature 3
A Digital Diary to Visualize Past Hangout History
User goal
View past hangout histories or notes
