Brazilian Jiu-Jitsu is a form of martial arts that builds the body and mind and helps bring discipline into practitioners’ lives. After working so closely with the client who was a BJJ fighter, it was evident that this sport helps individuals increase confidence, become more centered and become resilient.

Business Problem

User/Domain Research

1. We sent out an online survey to find as many fighters within the short time frame provided across different regions and received 28 responses.

2. We conducted one-on-one interviews with fighters to collect answers to more complex and in-depth questions.

It was evident that BJJ fighters share the exact same needs, goals, and views on life. It was the first time that I was seeing such unified answers across interviewees, no matter the job title, pay grade or fitness level. After close consideration, we created Ali as our typical user to help tailor the app. Meet Ali:

Through our data analysis we found out that 68% were unable to practice more due to cost, long commute, injuries and gym timetables.

Differences of Opinion


In the process of finishing the storyboard.
The client really enjoyed seeing the interaction of the user with the app.

Our client enjoyed the hand drawings and was delighted by the accuracy of the picture in ‘watches the video’ frame.

Usability Testing

The fighters that we tested, enjoyed using the app and repeatedly asked when they can go ahead and use the final app. Other than minor design changes the app was well-received.

Future Consideration

  1. Kids section
  2. Step-by-step transcription of BJJ moves

The interviewees all had the same needs and had similar personalities. Due to the clarity that needed to be done the project was fairly smooth from beginning to the end.
