Redesigning Patook

Story behind the app

Ever felt alone in the city? You’re not the only one. Between recent graduates, people who recently went through a breakup, and those new to the area, plenty of people could use a friend. (Over 40,000 people moved into Los Angeles in 2016, and certainly not all of those transplants came with fully formed support networks!)

Some find it easy to leverage their personal networks to form new connections, but it’s not quite so simple for everyone. I chose to tackle this issue by redesigning a friend-finder mobile application for my Springboard capstone project.

Mobile applications such as Bumblebff, Hey! Vina, and Patook enable users to “match” with others in their area and converse to develop platonic friendships. Users share information and identify common goals/interests in their profiles, which include a combination of personal user photos and self-written descriptions. Users are able to view other users located within a radius of their choosing. Upon viewing each profile, users indicate whether or not they are interested in talking to someone. Mutual interest will enable the two to chat together. It is up to the matched users to strike up a conversation and escalate to an in-person meeting.


Validate the desire for a friend-finder app and create the first prototype for usability tests.

Research and planning

What I wanted to explore:
  • Current friend-finder applications and their functionality/design
  • How people seek out and maintain new friendships
  • What qualities people look for when making new friends
  • How familiar people are with existing friend-finder applications
  • What may hinder someone from using a friend-finder application
  • Frustrations with existing friend-finder applications
  • What people are willing to share about themselves for the purpose of making friends


I evaluated the most notable competitors in the field, including the original Patook application. I judged each one on how well they followed the design heuristics of user control/freedom, flexibility and efficiency of use, and aesthetic/minimalist design.

Bumblebff demonstrated its strengths over the other two apps, based on these heuristics.

Screener survey

I wrote questions for a screener survey to determine interview participants. These questions gauged people's satisfaction with their social circles' size and quality. I wrote questions such as “How do you usually meet new people?” to identify current methods of expanding their personal network.

This survey also provided insight on qualities people sought in friends. Trustworthiness, authenticity, reliability, kindness, and similar values were some of the ones that came up. This helped to form tentative "how might I" statements to guide my design thoughts:

  • How might I help bring people together when they aren't aware they have common interests to talk about?
  • How might I demonstrate to someone that their trust is well-placed?
  • How might I encourage one to display their authentic self to someone new?

User interview insights

I interviewed those who had self-identified as dissatisfied with the size/quality of their social circle. Regardless of their experience with (or feelings about) friend-finder applications, this group provided many insights about their attempts to expand and develop their friendships.

Common frustrations:
  • While surface commonalities (same hometown or heritage) help to quickly identify other commonalities, lacking common interests limits the scope of the potential friendship.
  • Those with experience with friend-finder apps mentioned that they had difficulty finding others with common interests, and that receiving responses took a while after the mutual match was first declared.

Common behaviors:
  • Millennials are very comfortable with texting as a convenient, casual way to quickly get their thoughts across.
  • All confirmed that they view one-on-one interactions as more intimate, so prefer to get to know newer friends one-on-one before integrating them into a larger group.
  • Most people prefer in-person interactions but will use texting or phone calls to quickly plan and set their next meetup.

Common goals:
  • Most find it fairly important overall to share common interests with friends.
  • While it isn’t a dealbreaker for friendships that already exist, common interests are used to quickly establish a common ground and an ever-evolving source of conversation besides regular life updates.
  • Most expressed excitement at the prospect of being able to meet with new people who shared interests that few of their other friends held.
  • Friend-finder apps are best for those who live far from their original social circle (newly moved) or who have recently changed circumstances.


With this in mind, I set out to design an app that would focus on users’ common interests but also shine a spotlight on the interests unique to each person, in hopes that it would inspire new interests and different routes of conversation.

Designing for the users

I created three personas that represent users’ frustrations and goals as indicated from research and interviews. My primary persona Rena is a recent graduate who has moved to Los Angeles and wants to explore her new city. She epitomizes the desire of those who have moved far from their original social circle and are searching for companions for local activities.

My other two personas, Elaine and Kevin, represent other segments of the population who crave companionship - Elaine wants to find friends her age who are also new moms, while Kevin wants to get in touch with people who have similar hobbies.

All of these personas shared one thing in common: they felt their social circle was somehow incomplete.

User Personas User Personas User Personas

I used these personas' behaviors and goals to inform my design decisions. When crafting the user stories, I considered what features would bring people together while highlighting individual interests.

Addressing self-conscious users like Rena, I mitigated the "fear of rejection" driving force by including an icebreaker message feature. By using quick, easy-to-access icebreaker greetings/questions, users would be able to initiate conversation with new matches with less worry about what to say or ask at the beginning of conversation.

User Stories

The user stories would help to prevent scope creep, as a handy reference tool throughout the sketching and prototyping processes.

User Flow


I took the feature requirements generated in the user stories and began sketching. These sketches laid the groundwork for my clickable prototype to be used for usability testing.

Sketching process

I sketched wireframes and flows, considering what interface design patterns might be most appropriate for the target audience.

I synthesized the feedback from my interview participants and the results from my competitive analysis to form a solution. I knew from my research and heuristics evaluation that the resulting app needed to allow power users the freedom to use the app’s nooks and crannies, while remaining easy and approachable enough for first-time users to not be intimidated by the sheer scope of the app.

Navigation Bars

Based on research about how smartphone users hold their phones, I knew a bottom navigation bar would be most accessible. I sketched out a few different options for the navigation bar, but one thing stayed consistent: Tabs were ordered by priority, starting with the Mutual Match screen and Conversations screen.

Important call-to-action buttons were placed in the bottom half of each screen. Otherwise, users who hold their phone in one hand and use the thumb of that same hand to touch the screen would have difficulty accessing buttons at the top of the screen.

Developing the prototype

Generating the prototype took longer than anticipated – while I was not trying to spend too much time on the visual design aspect, I did want to ensure that the users of the first prototype received sufficient guidance through visual and textual cues. Upon creating my high-fidelity wireframes, I began putting more thought into word choice.

Most of my efforts during the sketching process were concentrated on how information would be most effectively communicated through the visuals. Keeping in mind the “call to action” I wanted users to take on each page and the hotspots most easily accessible on a user’s smartphone, I settled on a Z-formation structure for most of my pages, with a bottom navigation bar to make it convenient for thumbs.

I validated the design with feedback from the same participants I'd interviewed during my research processes.

I conducted usability tests over the course of several days, using a script to guide users' interactions with the prototype. I organized user feedback and concerns by section: Login/Signup, Conversations, Profiles, and Settings.

Overall, prototype feedback ranged from compliments about the design’s minimalistic and “clean” look/feel to confusion surrounding some of the functionality. One section that particularly confounded certain users was the “Use My Location” option during onboarding - they were unsure how selecting that button would differ from manually entering their zip code below.

I addressed these concerns by tabulating a list and prioritizing them based on ultimate functionality and purpose in the process. By doing so, I concentrated my efforts only on the essentials rather than getting distracted by feature/scope creep.

Reflection and next steps

Limited functionality in Invision: I had greater ambitions for this utility app, which were unfortunately beyond the scope of Invision’s functionality. If given the opportunity to work with a developer, I would like to implement more advanced interaction design: transition screens for swiping left-right to more clearly indicate how a user is swiping, allowing them the satisfaction that they are swiping the way they intended to, swiping up to temporarily skip a profile, and a filter for different community groups to narrow search options to only those with certain characteristics.
