Billow is a social media in which users can easily explore nearby activities and invite friends to join together. As well the platform can show complete event detail users need to know, which makes the researching process more convenient.

The Research

We collected data by doing online surveys and in-person interviews in order to understand how people think about social media. After the survey, we also picked up a few interviewees to continue the field observation to fully understand their event searching processing with personal experience 

When asked “What social media do they use the most frequently?”  
  • 70 % of interviewees use Instagram the most frequently

  • 22 % of them use Snapchat 

  • 8 % of interviewees use Facebook 

People love the story feature but, “how do they find events you are interested in online?”
  • 50 % of interviewees use story features to explore new events, but mostly those events are not nearby them and unable to join

  • 25 % of receiving private messages from friends about new events they may be interested in

  • 12.5 % of seeing Facebook event pages so that they are notified about new events around their current cities they are living at

After a long story viewing, and how do they get a comprehensive understanding of what the event is about?
  • In this section, their answers are too diverse to be presented with clear steps or categories

  • Eventbrite, Facebook event page, official event websites or other ticket-selling pages, people need to go through different mediums to complete the searching

  • A number of  percentage of interviewees reported that sometime event description  is vague

       We picked up a couple of interviewees to do the field observation and found out that 

Finally, they find the event they want to go to and,” how do they invite your friends to attend with them?”
  • 50% of interviewees answered that they would send private messages for the invitation

  • 12% of them said they don't invite people

  • 38% of them did not clarify how they would invite friends in detail

The Problem

By gathering the feedback related to social media, we discovered that the general issues people may have during their event researching are as follows:

  • Users love randomly scanning through stories to find something that catches their eyes, but the result may end up with events too far away from them

  • Interviewees would go to multiple mediums websites back and forward to comprehensively understand the event content. The unclear processing is the biggest issue to make the event searching inefficient

  • Event descriptions are vague

  •  There are not social media with event location filters to show nearby activities they can attend

  • There is no certain way for people to send event invitations and invite friends going together

Billow's Goal

After going through users' journey and pointing out a few inefficient steps users may face, and I think Billow should contain

  • Event location filter to show nearby activities

  • Sending invitations to ask friends going events together

  • Story feature make better work to descript event content

Paper Prototype
Competitor Analysis

We observed other social media, and none of them can filter nearby event around and share event story at the same time

Billow Branding
Competitor Analysis

We observed other social media that help users to look for new activities and invite them to friends, and none of them dresses to match people who have the same interests. 

After putting the existing solution into a 2x2 matrix, I am able to find out the strengths of this APP  
  • A mobile app that suggests fun activities based on users’ current location, is able to update live stories about the event you are attending, and easily invite friends to join with them.

The Solution
  After going through users' journey and pointing out a few inefficient steps users may face, and I think it should be
  • Billow allows the users to research fun activities around their current location, to match/contact with people who have the same interests, and also to update their story video about live events. After research, we found out the searching event and inviting friends processing has been slowed down and been inefficient on social media. So, we decided Billow to let people easier reach out to people to join activities together. 

Here is the main feature to do the "Problem Solving" 
  1. Event filters

  2. Story feature

  3. Send invitations

  4. Matching feature

Paper Prototype 
  What do we want this social media iOS APP?
  • We want the map page showing pins, and each pin is represented as a unique event. Each pin should be clearly pointing on the map so that users can have a better sense to know where and how long the distance the user from the event. Apart from showing events around users' current locations, there should be a button that users can switch to see those events of their followings. It can know what events are happening globally. In addition, once a pin was clicked, the event detail will be stretched and users can see how other internet friends are interacting. By clicking the add event button on the map, users can easily share their joy from activities on the internet and make more friends

  What kinds of features will we implement?
  • There are eight basic principles we want to implement on this app, and to quickly test our concept, we created paper prototyping. To quickly test our concept, we created paper prototypes that demonstrate key user flow.

  • The paper prototype allowed us to brainstorm on main features without expending too many resources.  We iterated on our wireframe by conducting guerrilla usability testing with paper prototypes. With a total of 8 participants, we aimed to validate the solution concept, clarity on components.

High-Fidelity Prototype
  • After searching and completing guerrilla usability testing with paper prototypes, the direction on how to design the final high-fidelity prototype and approach the problem is more clear in this project. 

  • Here is the prototyping design 🤩 


Generally, the search page is a map that presenting the user's current location and the city around them. And there are a couple of keys functionalities in this page

Event Selected


  • After entering a keyword for event searching, a window will pop up with related events around the user's current location.

 Selected event status 

  • Users can update their own event status for each event.
  • "Going", "interested", or "not interested".
  • After the update the event status, the user can receive the newest events' notification.

Event Calendar

Search bar

  • On the top of the search page, there is a search bar for users to target the event keyword they are looking for. Once, the keyword is entered and a search result window will pop up.


  • The icon next to the search bar is the calendar. After confirming going to an event, the notification of the calendar will turn on and save the event in the schedule. 
  • By pressing the icon, the page will be navigated to the calendar page, which shows the following event that the user is interested in or confirms to go.

Event Filter


  • Users can customize the filter, like what time they prefer for the event, how far the event is away from them, or sorting the event by specific.

Filter setting

  • After setting up and update the filter, the sorted events will be updated on the page.

Event Comment

Event Comment

  • By clicking the event comment, it can view others' comments and event reviews. Also, it is sharable with friends.

Event Page

Event Story 

  • By clicking the story circle, the story will show on the screen and is able to view the live video of the event.

Event Page

  • The event page collects the details of the event, including, the location, time, ticket resource, description, and official website. In addition, users can see who is going to the same event among their friends.

Event Followings

Event Followings

  • On the page of the event follows, users can view their friends' current event stories worldwide and get the newest update of the event they are following. 

The difference between event search and event followings 

  • Event following primarily presents the stories of followings and receive the newest event updates users like. It will be less considered users' physical location.

  • Event search aims to explore nearby events based on users' current location and sort events into different categories. 

Event Invitation


  • People can send an event invitation to friends and share the information with them.

The new idea of invitation

  • Part of the future part will focus on how users can customize their own invitation emoji or cute animation. I want users to experience interaction through the process of sending an invitation to their friends and have a sense of ceremony.


The mission of Billow is to let people easily find fun activities around them and invite friends together. Also, to share live event videos worldwide. To spread the joy, we make Billow include the match feature so that users can explore fun activities with new friends. 


Match Feature

  • Users can find someone who has similar events interesting and invite them to go to explore the fun. 


By pressing the share button, users can film their event story and share it to selected friends or the public.



  • Users can record videos about the events they have been going to, and post them on own profile page as memories.

Video editing

  • Users can create unique event videos with those editing tools.

Update event information

  • After recording the event story, users can update the event information and share it with others. The update will be collected by algorithms and create own event page to attract more people who have a similar taste as you, and then they may join with you.

Share event story

  • The owner can decide either share the event story with the public or with specific friends only.  They manage how their profile will look like from different views.


Users can privately send messages and make invitations to friends.


Message Feature

  • In the message box, users can freely text with their friends, and share event invitations to each other. In advance, after the user confirms the event invitation, it can save to own calendar and receive customized event animation.

Inbox Feature

  • The inbox page shows messages from others who are not users’ friends. After the users accept others' friend requests, the message will be moved to the general message box for protecting users' privacy.


The Profile page records individual event stories and activities they are interested in.


Event Story 

  • Event stories record users' journey an experience. In advance, users can set up own privacy for each event story, either they are presented in the public, or only showed few special friends.

Interested Event

  • Interested event feature collects users' habit and interesting, which let more people know the users.


  • The notification page shows current news and follows up events they are interested in. Also, the user can see who send a friend's request to them and view their personal profile page.
