joinIn
Making spontaneous meetups easy.
Note from the present: this is an older project that I've kept here for nostalgia :) It was a fun pandemic-era side project.
I often face the problem of wanting to do an activity with friends, but not knowing who would want to join. Once I realized how frequently I face this problem, I decided to create a solution.
Problem: I want to do something with friends, but don't know who's available or interested in joining me.
Solution: To address this problem, I designed an app where interested and available friends come to you.
1. EXTRACTING USER INSIGHTS
Planning group activities can be difficult without knowing friends' availabilties.
I wanted to see if others faced this problem, and to what extent. I interviewed college students and conducted research on Reddit and Twitter to learn more about user pain points.
Affinity diagramming to cluster observations into insights
Here are a few of the user insights:
2. BRAINSTORMING CONCEPTS
I used user insights to brainstorm features. I looked to popular social apps among college students for visual design inspiration.
I was interested in designing a solution that I could develop myself. I have some iOS app development experience, so I chose to design an app.
Brainstormed app features & design goals based on interview insights
I drew my visual design inspiration from apps that are popular among college students today, such as Venmo, Snapchat, and Instagram.
3. DESIGNING THE PROTOTYPE
After some lo-fi iterations, I created the prototype on Figma with a simple, playful color scheme.

4. RESULTS & REFLECTIONS
90% of user test participants said they would use this app frequently. All users found the app to be easy-to-use and intuitive.
Many users were very excited about the idea and saw themselves using it!
