Niquitine App— Design Report

Understanding the challenge

Smoking cigarettes is tied to numerous health problems. Some of them are listed here:

  • cancer,
  • heart disease
  • stroke
  • lung diseases
  • diabetes
  • chronic obstructive pulmonary disease (COPD)
  • tuberculosis
  • certain eye diseases
  • problems of the immune system, including rheumatoid arthritis.
  • more


The Survey

I created a survey of 10 questions to get to the bottom of why people smoke and how can I help them discontinue this habit.


I interviewed 8 people between the ages of 25–40, have white collar jobs, and mid-high level income.

  • motivations to quit
  • feelings that created cravings
  • common situations that made people smoke
  • methods to quit

Low-fidelity wireframes

I did some sketching but it was just to explore a few user flow options. I decided on the onboarding + logging a craving user flow. I jumped too soon to wireframing and in retrospect, it wasn’t the best decision. Doing some crazy 8’s would really increase my efficiency and helped with the convergence stage.


As a next step, I had some CRITS sessions with teammates. CRITS(critique) are done with other team members or stakeholders to share and comment on the work done. It’s a way to validate your design decisions and get feedback.

Usability tests

I’ve done 3 usability tests before I made too many changes based on the feedback from the CRITS. And what mentioned during the CRITS also came up during the usability test.

Feedbacks and iterations

  1. Removing the screen about how the app uses the behavioral discovery method.

Final Prototype


Not investing in sketching and Crazy 8’s was a mistake that caused problems. I think the research findings and solution-features were related. But communicating those features with user experience in mind needed definitely more work.
