Rapid Prototyping

Case Study ‘Quiet App’

Working with a participant ‘Cat’, who likes going to the gym but doesn’t like the journey getting there due to the crowds, I set out to create a mobile app which would allow ‘Cat’ to have a less stressful and crowded walk to the gym with a divesion time of 5 minutes.


I gave myself a week to build a low fidelity rapid prototype and test it with ‘Cat’ and different participants, making a change then testing it once more. I conducted user research to see what ‘Cat’ was trying to accomplish then I used visual research to better explain ‘Cats’ needs before building the rapid prototype.

A Concept Map that I created

The concept Map allowed me to expand on my mobile app ‘Quiet Walk’ which was incredibly useful to depict the relationship between walking, route, diversion and crowds. Avoiding the crowds is on the most important parts of the app so I looked into what relationship this has with ‘Cats’ other needs.

Low fidelity sketches. Representing the start of how my app might look.

I was interested to know how effieciant the app would be, especially how the diversion time affected the time of arrival. These sketches were the start to get an idea of how the app might look before I make other versions and use it in the Pop app to test on ‘Cat’.


After showing my sketches to ‘Cat’ and other participants on Pop app I found that having a preview screen before the start of the destination worked well in keeping the efficancy. I needed to encorporate more onto one screen and focus on meeting her goals in the future as some ideas turned out to be unneccessary for the app.
