Platform: iOS

Tools: Illustrator, Adobe XD

Design Brief:

A few trends of note: 54% of the world’s population lives in urban communities, the average marriage age for men is 29 (up from 26 two decades ago) and for women is 27 (up from 23 in the same period).


Given these trends, city dwellers tend to spend most of their twenties living with roommates. Finding and keeping a good roommate, however, gets harder as more people swarm into cities.


To alleviate this problem, we want to design a mobile product that targets millennials and make it safe for them to find an ideal roommate in Toronto.


What should this product do? How should this product work?

Challenge Considerations:

  1. Explain in words how the product works. Specifically, think about how roommates are paired, what the experience is how they might proceed to become roommates. What criteria do you think the user will want prioritized?

  2. Design a low-mid fi wireframe for the main screens.


Mobile (iOS/Android) app

Stick to reasonable mobile capabilities (screen based interface, location services, mapping, photo access, etc.)


Our Group: We were about seven members in total. Our design background and knowledge were very multifaceted. Some of us were new to the work of user experience and interface design. Some of us were transitioning to the field from other careers. A large sum of us were fresh out of a boot camp or accelerated training program focused on user experience design.

The Process:  As a group, we felt that targeting millennials needed to be more refined. Doing a quick user persona exercise, we felt we needed to flesh out an ideal user who would benefit from this service. Due to the confines of a set time limit to complete the challenge, we had to make assumptions of our ideal user. We did not have time to create a formal survey to gauge more millennials.

For our typical user, we wanted to focus on young Toronto resident who in the past lived at home looking to venture out on their own with a roommate. We decided to on age range suitable for a young adult attending 1st to 2nd-year college or university. We wanted to set a financial background, to establish what could a millennial afford to pay for rent in Toronto. A decision was made to give this persona a type of part-time employment while studying at a post-secondary institute.

After The Meetup

Mood Board

Early research made me search for what current millennials look for in-room decor. Millennials love to do social activities in an open environment. Looking over home decors I thought about playing with a simple isometric floor plan look. 

Colour Palette

I begin looking up colour trends that would appeal to millennials. From reading a few online home decor publications, I came to the conclusion that earth would be the trend of 2019. 


I came across Industry and Columbia Tiling, in the use of typefaces that are currently trending in the millennial space.

User Persona

User Flow

The user flow currently focuses on the on-boarding of the user, creating a personal profile. After the personal profile, a series of questionnaires will be filled out by the user. We then move on to questionnaires pertaining to the living environment and needs the user would like to be matched with. From there the main screen would be a home map based on the geographical location.
